Description
At 250 A, the cable becomes part of the instrument. The Keysight N8754A DC power supply pairs a 20 V ceiling with 250 A on one output, at a 5000 W rating, in the N8700 Series. Lost in HCM lists it for rental and sale in Vietnam, and it arranges repair intake on request.
Why 250 A changes the plan
High-current connections need an engineering review of the conductor rating and the connection resistance. A weak joint wastes power and runs hot, so inspect every joint before you load the output. Multiply 20 V by 250 A and you get exactly the 5000 W rating, so real test points will often sit below that corner.
Batteries, charging and power electronics
Teams in automotive and energy work apply a source like this to power electronics, batteries, charging hardware and control systems. Review grounding, isolation, power and regulatory limits first. Treat remote sensing and series or parallel operation as configuration-specific, so read the Keysight manual before you plan them.
It is a plain DC source. As a result, it does not stand in for a bidirectional battery emulator or a regenerative supply.
Site checks before delivery
- Facility power that matches the AC-input option on the label.
- Grounding and ventilation around the unit, because a 5000 W source runs warm.
- Rack space or bench room, plus a safe route for heavy cables.

Ordering the Keysight N8754A DC power supply
Rent the Keysight N8754A DC power supply for a charging or load campaign, then buy if the work repeats. To begin, request a quote from Lost in HCM and describe your cables, protection limits and delivery city. Also see the power supplies category for related units. Questions about the listing go to SMK Vietnam, and the Keysight website covers the maker.
N8754A questions
Is 250 A available at every voltage?
No. The output tops out at 20 V and 250 A, which gives the 5000 W rating. Then check your own operating points on the Keysight data sheet.
What should I confirm about the cabling?
Confirm the conductor rating, the connection resistance and the output terminal arrangement with an engineer. The Keysight user guide covers terminals and remote sensing.
Can it replace a regenerative supply?
No. It sources power only, so check energy flow, inrush and shutdown needs before you rely on it.
