Pacific Power Source (pacificpower.com) builds programmable AC power sources across several series, ranging from 1.5 kVA benchtop units to regenerative systems rated up to 1.296 MVA. The right series depends on three things: whether you need regenerative (energy-recycling) operation, whether you need AC only or combined AC & DC, and how much power your test requires. The table below maps each series to its type and power class based on the company's product listings.

AC power source series at a glance

Pacific Power Source also lists combined AC & DC versions of several of these lines — the AZX, AGX, AFX, and ADF series each appear in both an AC-only and an AC & DC configuration.

How the series differ

Regenerative vs. non-regenerative

The AGX and AZX series are described as regenerative, meaning they can recycle power back to the grid rather than dissipating it as heat. The AZX additionally supports PHIL (power hardware-in-the-loop) testing. Regenerative operation matters most in high-power, long-duration, or bidirectional test setups — for example, testing a motor drive or inverter that normally returns energy to the source.

The AFX, ADF, LSX, and LMX series are listed as conventional programmable AC sources without the regenerative designation.

Linear vs. switching

The LMX Series is the one explicitly described as a linear AC power source. Linear designs are typically chosen when very low distortion or low noise matters more than efficiency or size. The other series are not labeled linear in the source material, so treat LMX as the option to evaluate when signal purity is the priority.

AC only vs. AC & DC

If your device under test needs both AC and DC input, the AC & DC variants of the AZX, AGX, AFX, and ADF series cover that in one unit. If you only need AC, the AC-only versions of the same series apply.

Power range and what it implies

• LSX (1.5–6 kVA): the low end of the range, suited to bench or lab-level testing of smaller products.
• AFX / ADF (up to 180 kVA): mid-to-high power for larger subsystems.
• MS (up to 625 kVA): AC power conversion at substantial scale.
• AGX (up to 1.296 MVA): the highest listed rating, aimed at large-scale or grid-level test setups.

These figures come from the product descriptions on the site; confirm exact models and configurations with Pacific Power Source before specifying.

Choosing a series by application

The site organizes solutions by market, which is a useful filter:

• Aerospace, Military & Defense — high-reliability AC and AC & DC sources; regenerative options help with long test runs.
• EV & EV Charging — bidirectional and grid-interactive testing benefits from regenerative series (AGX, AZX).
• Renewable Energy — inverter and grid-tie testing, where the SmartTS-PV Inverter Grid Compliance Test System and regenerative grid simulators are also relevant.
• Data Center & Network Servers — power design validation.
• Power Design & Validation / Research & Academia — the full range, from LSX benchtop units up.
• EMC Compliance Testing — paired with the SmartTS-HFI harmonics, flicker, and immunity test system.

A practical selection path:

1. Decide whether you need regenerative operation (high power, bidirectional, or energy-sensitive tests) → AGX or AZX.
2. If not, decide whether you need AC & DC in one unit → AC & DC variant of AFX or ADF.
3. If signal purity is critical → evaluate the LMX linear series.
4. If you only need a small benchtop source → LSX (1.5–6 kVA).
5. If you need very high power → AGX (up to 1.296 MVA) or MS (up to 625 kVA).

A note on legacy NI/NHR hardware

Pacific Power Source highlights that Emerson/NI will stop supporting the NH Research NHR 9410/9420/9430 and 9510 series after 12/31/26, and positions itself for teams facing that obsolete hardware. If you are replacing an NHR 9410, 9420, 9430, or 9510, the replacement path is worth discussing directly with Pacific Power Source, since the mapping depends on your specific power and feature requirements.

Getting specifics

The site lists phone (+1 949-251-1800) and email ([email protected]) contacts, and the site is available in multiple languages including English, Spanish, French, German, Italian, Chinese, Japanese, and Korean. Because the listings do not state pricing or full model-level specifications, contact the company for configuration, pricing, and availability for your application.

Pacific Power Source's grid simulators (RGS and GSZ series) and regenerative loads (RLS and ELZ series) are used to test equipment that connects to the electrical grid — solar inverters, EV chargers, data center power systems, and similar products. The grid simulators recreate the AC (and in some cases DC) conditions of a utility grid so a device under test can be evaluated against compliance standards, while the regenerative loads absorb and recycle power back to the grid instead of burning it off as heat. Both product families scale from roughly 1 MVA up to about 1.3 MVA, which puts them in the range of full-power, utility-scale test benches rather than bench-top lab equipment.

Grid simulators: RGS and GSZ series

A grid simulator is a programmable AC source designed to behave like the grid itself — including the disturbances a real grid produces. That means it can generate not just a clean sine wave but also voltage sags, swells, frequency shifts, harmonics, and other anomalies that compliance standards require a product to survive.

Pacific Power Source lists two regenerative grid simulator lines:

Both are described as regenerative, meaning power drawn by the device under test can be returned to the facility rather than dissipated. This matters at these power levels: a 1 MVA test running for hours converts a large amount of energy into heat if it is burned off conventionally, which drives up cooling requirements and electricity cost.

What grid simulators are used for

• Grid compliance testing — verifying that an inverter, charger, or power supply meets the ride-through, power quality, and interconnection requirements of a given grid code.
• PV inverter testing — the site highlights a dedicated SmartTS-PV Inverter Grid Compliance Test System, which pairs with this class of hardware for solar inverter certification work.
• EV and EV charging — testing onboard chargers and charging equipment against the AC conditions they will see in the field.
• Aerospace, military, and data center power — the same programmable-source capability applies wherever equipment must be validated against a controlled AC input.

Regenerative loads: RLS and ELZ series

A regenerative electronic load does the opposite job of a source: it absorbs power from a device being tested. The "regenerative" part means that absorbed energy is converted and returned to the grid instead of being turned into waste heat.

These are used when you need to discharge or load a product at high power — for example, testing an inverter's output, a bidirectional charger, or a power conversion system — and want to do it without a resistive load bank that would otherwise require substantial cooling and consume the full test power as waste.

Why "regenerative" is the key design choice

The practical difference between a regenerative and a non-regenerative test setup comes down to three things:

1. Energy cost — recycled power is not simply lost as heat, so long-duration high-power tests cost less to run.
2. Cooling and facility load — dissipating hundreds of kilowatts to over a megawatt as heat requires significant HVAC and electrical infrastructure; regeneration reduces that burden.
3. Test duration feasibility — tests that must run for extended periods become practical when the energy is recovered rather than burned.

The trade-off is that regenerative equipment depends on a suitable facility connection to accept the returned power, so it is not a drop-in replacement for a simple resistive load in every lab.

Choosing between the series

The two grid simulator lines and two load lines overlap in function, so the decision usually comes down to required power level and the specific test standard being targeted:

• If your test plan needs the highest listed capacity, the RGS and RLS series go to 1.296 MVA.
• If your requirement sits somewhat lower, the GSZ and ELZ series are listed at 1.1 MVA+.
• If your work is specifically PV inverter certification, the SmartTS-PV system is the purpose-built option rather than a general-purpose source.

For anything beyond these headline figures — accuracy, transient response, specific grid codes supported, or how a series integrates with the SmartSource Suite test software — the specifications on pacificpower.com are the authoritative source, since those details determine whether a given unit actually satisfies a particular compliance standard.

A notable detail: NHR product replacement

The site flags that Emerson/NI will stop supporting the NH Research NHR 9410/9420/9430 and 9510 series product lines after 12/31/26, leaving engineering teams with obsolete hardware. Pacific Power Source positions itself as a replacement path for those NHR users, so if you currently run NHR 9410/20/30 or 9510 equipment, this is the page to start from.

How to use the site

1. Pick your application under Solutions (for example, EV & EV Charging or EMC Compliance Testing) to see which product families apply.
2. Or go straight to Products and filter by type — AC power source, grid simulator, electronic load, or test system.
3. Note the power range in each product name (for example, "up to 180 kVA" or "up to 1.296 MVA") to narrow down before contacting sales.
4. For pricing, configuration, or lead time, use the contact details published on the site: +1 949-251-1800 or [email protected]. The site does not list prices, so treat any purchase as a quote-based process.

The site is available in English, Spanish, French, German, Italian, Simplified Chinese, Japanese, and Korean.

Pacific Power Source addresses this directly on its site: it maintains a "Need NI / NHR Product Replacements?" entry point aimed at teams affected by the end of Emerson/NI support for the NH Research NHR 9410/9420/9430 and 9510 series product lines after 12/31/26. If you run those units, the practical path is to identify the replacement category that matches your test function, then contact Pacific Power Source sales with your existing model and requirements.

What is changing with the NHR 9410/9420/9430/9510 lines

According to Pacific Power Source's site, Emerson/NI will no longer support the NH Research NHR 9410/20/30 and 9510 series product lines after 12/31/26. The site frames the situation as engineering teams facing obsolete hardware, which is the trigger for looking at replacement options.

The date is the key planning constraint: it is a support cutoff, not necessarily an immediate failure date, but it defines how long you can expect vendor backing for those models.

How Pacific Power Source positions itself as a replacement source

Pacific Power Source describes itself as a provider of programmable AC power sources, DC power supplies, grid simulators, loads, and EMC test systems for the aero/mil, EV, renewable energy, and power markets. Its catalog covers the functions that NHR-series users typically need, organized into these categories:

• AC power sources — regenerative AC with PHIL (AZX Series), regenerative AC up to 1.296 MVA (AGX Series), programmable AC up to 180 kVA (AFX and ADF Series), programmable AC 1.5 to 6 kVA (LSX Series), linear AC (LMX Series), and AC power converters up to 625 kVA (MS Series)
• AC & DC power sources — regenerative AC & DC with PHIL (AZX Series), regenerative AC & DC (AGX Series), and AC & DC up to 180 kVA (AFX and ADF Series)
• Regenerative grid simulators — up to 1.296 MVA (RGS Series) and up to 1.1 MVA+ (GSZ Series)
• AC & DC electronic loads — regenerative load simulator up to 1.296 MVA (RLS Series) and regenerative electronic load up to 1.1 MVA+ (ELZ Series)
• EMC compliance test systems — SmartTS-HFI harmonics, flicker, and immunity; EPTS Series immunity; SmartTS PV inverter grid compliance
• Test software and cabinets — SmartSource Suite, Remote Control Platform, PPSC Manager, and cabinet systems

The site also lists the NHR 9410, 9420, 9430, and 9510 series by name in its replacement messaging, which signals that these are the specific models the replacement program targets.

How to choose a direction before you call

The right replacement depends on what your NHR unit does in your test setup, not on the model number alone. Use these matching questions:

Power level matters as much as function: the catalog spans from 1.5 kVA (LSX) up to 1.296 MVA (AZX, RGS, RLS), so bring your required voltage, current, and power range to the conversation.

Contacting Pacific Power Source

The site lists these contact channels:

• Phone: +1 949-251-1800
• Email: [email protected]

The site is available in English, Spanish, French, German, Italian, Simplified Chinese, Japanese, and Korean, so you can work in the language your team prefers.

What to have ready

To get a useful replacement recommendation rather than a generic catalog pointer, prepare:

1. Your current NHR model (9410, 9420, 9430, or 9510) and how many units you run
2. The test function it performs in your lab
3. Required AC/DC voltage, current, power, and frequency range
4. Any grid simulation, PHIL, or compliance standards your testing must meet
5. Your timeline relative to the 12/31/26 support end date

Pacific Power Source's site does not publish pricing or a self-service replacement configurator, so the replacement path runs through sales contact rather than an online selection tool.

Pacific Power Source offers three named compliance test systems: the SmartTS-HFI for harmonics, flicker, and immunity testing; the EPTS Series immunity test system; and the SmartTS-PV inverter grid compliance test system. These sit alongside its programmable AC/DC sources, regenerative grid simulators, and regenerative loads, which supply the power and load conditions the compliance systems test against. The right choice depends on whether you are qualifying a product against EMC standards, qualifying a PV inverter against grid codes, or both.

The three compliance test systems

SmartTS-HFI — harmonics, flicker, and immunity

SmartTS-HFI is described as a harmonics, flicker, and immunity test system. In practice that means it is aimed at the EMC side of qualification: measuring and verifying harmonic current emissions, flicker behavior, and immunity to disturbances. It is listed under both the EMC Compliance Testing solution area and the EMC Compliance Test System product category, so it is the entry point when your requirement is an EMC standard rather than a grid code.

EPTS Series — immunity test system

The EPTS Series is listed separately as an immunity test system. If your test plan is scoped to immunity only — rather than the combined harmonics/flicker/immunity scope of SmartTS-HFI — EPTS is the dedicated option in the lineup.

SmartTS-PV — PV inverter grid compliance

SmartTS-PV is presented as a new inverter grid compliance test system, and it appears under the Grid Compliance Test System category. It is the system to look at when the device under test is a photovoltaic inverter and the requirement is grid compliance rather than generic EMC. Because it is a grid compliance system, it pairs naturally with the regenerative grid simulators (RGS and GSZ series) that reproduce grid conditions.

How these fit with the rest of the product line

The compliance systems are not standalone instruments — they are the test-and-measurement layer on top of Pacific Power Source's power hardware:

• AC power sources — AZX, AGX, AFX, ADF, LSX, LMX, and MS series, spanning roughly 1.5 kVA up to 180 kVA for the programmable units and up to 625 kVA for the MS AC power converter.
• Regenerative grid simulators — RGS Series up to 1.296 MVA and GSZ Series up to 1.1 MVA+.
• Regenerative loads — RLS Series load simulator up to 1.296 MVA and ELZ Series regenerative electronic load up to 1.1 MVA+.
• Test software — SmartSource Suite, the Remote Control Platform, and PPSC Manager.

For a grid compliance program, the simulator or source provides the grid conditions and the compliance system runs the test sequence. For an EMC program, the source and load provide the operating conditions while SmartTS-HFI or EPTS applies and evaluates the disturbance and emission tests.

Which industries these systems target

Pacific Power Source lists these solution areas, and the compliance systems map onto them directly:

• Aerospace and Military & Defense — EMC qualification is a standard requirement for airborne and defense electronics, which points to SmartTS-HFI and EPTS.
• EV & EV Charging — onboard chargers and charging equipment face both EMC and grid-interconnection requirements.
• Renewable Energy — this is where SmartTS-PV applies, since PV inverters must demonstrate grid compliance.
• Data Center & Network Servers, Power Design & Validation, Research & Academia — general power test and validation work, where the compliance systems are used when a formal standard must be demonstrated.

A note on the NHR product lines

The site also flags that Emerson/NI will no longer support the NH Research NHR 9410/9420/9430 and 9510 series product lines after 12/31/26, and asks whether teams need NI/NHR replacements. If you are currently running one of those NHR series for AC or DC power test, that end-of-support date is the trigger to plan a replacement rather than a reason to change anything immediately.

Choosing between them

• If your requirement is an EMC standard covering harmonics, flicker, and immunity together, start with SmartTS-HFI.
• If your requirement is immunity only, EPTS Series is the narrower fit.
• If your device is a PV inverter and the requirement is a grid code, start with SmartTS-PV.
• If you need the power hardware underneath any of these — grid conditions, programmable AC/DC, or regenerative loading — that comes from the RGS/GSZ simulators, the AC source series, and the RLS/ELZ loads.

Because the site does not publish pricing or configuration details for these systems, confirm the exact standard coverage, power level, and cabinet configuration you need directly with Pacific Power Source ([email protected], +1 949-251-1800) before specifying a system.
