Description
Converters and storage stacks often need more than a few dozen volts. A Keysight RP7946A power system reaches 160 V with a ±125 A current rating, inside a 10 kW regenerative design. That mix opens a higher-voltage window than its 80 V sibling in the same RP7900 family.
RP7946A specifications
| Item | Value |
|---|---|
| Instrument type | RP7900 regenerative bidirectional DC power system |
| Maximum voltage | 160 V |
| Source/sink current rating | ±125 A |
| Rated power | 10 kW |
| AC input | Three-phase 400/480 VAC |
| Operating mode | Two-quadrant source and regenerative electronic load |
Matching the 160 V window to a test plan
The 160 V range and ±125 A rating suit well-matched converter test plans. Yet the two maximums do not occur together, since 160 V at 125 A would be 20 kW. Write down each operating point, the transient profile and the voltage overshoot you can accept. Then compare them with the 10 kW limit.
The RP7945A offers 80 V with ±250 A in the same family. So choose by which axis your device stresses more: voltage or current.
Regeneration in a shared lab
Because the system returns absorbed energy to a compatible facility supply, it wastes less than a resistive load. Two-quadrant operation covers both directions for bidirectional converters and storage devices. Plan throughput, thermal management, automation and traceable result storage before the rack goes live.
Safety comes first with stored energy. Review precharge, fault current, protection, isolation and emergency shutdown with qualified engineers. Also remember that the instrument alone does not establish compliance with a vehicle transient standard.

Keysight RP7946A power system questions
How does it differ from the RP7945A?
The RP7946A offers 160 V and ±125 A, while the RP7945A offers 80 V and ±250 A. Both are 10 kW.
Can it act as an electronic load?
Yes. It works as a regenerative electronic load, so it can absorb energy as well as supply it.
Is this page enough for technical approval?
No. Confirm the serial-number configuration, the quote and the current Keysight documentation before you order.
