What EMC and Grid Compliance Test Systems Does Pacific Power Source Provide?

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.
