Description
Endurance tests burn a lot of energy, and most of it normally turns into heat. The Keysight RP7936A power system takes another route. It is a 10 kW regenerative DC system in the RP7900 family, with 160 V and ±125 A ratings, and it sends absorbed energy back to a compatible facility supply. Lost in HCM lists it for rental and sale, with service on request.
Ratings at a glance
- Maximum voltage: 160 V.
- Source and sink current: ±125 A.
- Rated power: 10 kW.
- AC input: three-phase 200/208 VAC.
- Mode: two-quadrant source and regenerative electronic load.
Voltage and current are separate limits, so respect the power rating. For example, 160 V at 125 A would reach 20 kW, twice what the system delivers. Therefore plan each operating point inside the power envelope.
Planning a test on the Keysight RP7936A power system
Start with the converter or pack you want to exercise. Then write down the operating points, transient profiles, peak demand and the overshoot you can tolerate. Begin with conservative limits. After that, verify both source and sink behavior against the test plan.
Check the AC supply first
The input needs three-phase 200/208 VAC, so compare that with your facility supply before you book. The site must also allow regenerative energy flow. Qualified staff should approve protective earth, AC protection and DC cable sizing. They should also agree on isolation, energy discharge and emergency stop.
Jobs that suit a regenerative system
- Converter and bidirectional power-stage testing.
- Battery and energy storage development, after a review of chemistry, precharge and fault current.
- Low-voltage vehicle subsystems and industrial power modules.
- Long endurance and production runs with traceable results.
However, the system alone does not prove compliance with an automotive transient standard. Any battery-emulation software needs a separate check.
Rent, buy or arrange service
A validation campaign or a production ramp suits a rental, while steady daily use may justify a purchase. Please request a quote from Lost in HCM with your application, schedule and delivery city. See other power supplies on the category page. For a second opinion on options, contact SMK Vietnam. The Keysight website has the RP7900 data sheet.
Keysight RP7936A power system questions
What happens to the energy the system absorbs?
Regeneration returns it to a compatible facility supply instead of burning all of it locally. The site must permit that flow.
Is battery emulation included?
Not by default. Confirm any battery-emulation software separately, because the quote lists only the items you name.
Which details speed up a quote?
State the application, ranges, interfaces, accessories, schedule, delivery city and condition preference.
