Keysight N8921A DC Power Supply, 200 V, 70 A, 5000 W, N8900 Series

Description

Motor controllers and lighting drivers rarely agree on a bus voltage. The Keysight N8921A DC power supply can serve both, because one autoranging output covers 200 V, 70 A and 5000 W. It belongs to the N8900 Series, so it runs from 208 VAC three phase. Lost in HCM lists it for rental, repair and sale in Vietnam.

One supply instead of several fixed ones

A fixed-range source forces you to buy a different unit for each voltage. An autoranging unit instead lets you move along a power limit. As a result, several test points can share one supply. At 200 V the ceiling is about 25 A, at 100 V it is about 50 A, and at roughly 71 V or lower the full 70 A applies.

These figures simply divide the rated power by the voltage. Plot each of your test points against them, then confirm the result with the Keysight data sheet.

Specifications for the Keysight N8921A DC power supply

Motor-control and lighting benches

Review the supply against the test method you plan to run. An ECU, a lighting driver and a motor-control board each draw current differently at start-up, so write down the inrush and shutdown behavior first. This unit is a DC source. However, it does not replace a bidirectional battery emulator, a regenerative supply or a specialized automotive transient generator.

Factory teams can also use it for production screening. Document the start voltage, the current limits, the output sequence and the pass-fail rule. Then confirm the automation driver on a trial station.

Rent for a project or buy for the lab

Rent the Keysight N8921A DC power supply for a validation campaign or a production ramp. Instead, buy if the lab needs a mid-voltage source all year. If your own unit fails, Lost in HCM begins repair intake with the serial number, the symptoms and photographs. Meanwhile, SMK Vietnam only shows the listing.

N8921A questions

Can one unit replace two fixed supplies?

It can if both of your test points stay inside the envelope of 200 V, 70 A and 5000 W. So plot each pair before you decide.

What AC feed does the listing show?

208 VAC, three phase. Because the factory input option must match your site, ask for a label photo and the option list.

What comes with the supply?

Only the items itemized in the quotation. So check that cables, licenses and accessories appear on that list.
