Can Pacific Power Source Replace Discontinued NH Research NHR 9410/9420/9430/9510 Products?

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.
