Description
At 1500 V, the cabling matters as much as the supply. The Keysight N8957A DC power supply is an N8900 Series autoranging system with a 1500 V ceiling, a 30 A limit and 15 kW of rated power. Lost in HCM lists it for rental and sale.
Why 1500 V changes the setup
High voltage raises the stakes on insulation, spacing and guarding. So plan the fixture first, then the supply. For example, pick cables, terminals and enclosures that suit the voltage, and keep your test area clear of anything outside the circuit.
Also decide who may enable the output and how the team discharges the fixture afterward. Then write those steps into the test procedure.
Reading the 30 A limit
Maximum voltage and maximum current are separate limits, and rated power caps their product. A full 1500 V at 30 A would be 45 kW, three times the rating. Therefore the unit reaches 30 A only at 500 V or below. Held at 1500 V, it allows 10 A.
Your own operating points decide whether the Keysight N8957A DC power supply fits. If the test needs high volts and high amps together, compare the envelope with the data sheet first.
Where a high-voltage DC source helps
- DC-powered assemblies and converter inputs that run at high voltage.
- Screening and endurance runs where the same power-on sequence repeats.
- Controlled-load checks on industrial electronics.
It sources power only, so confirm energy flow before you connect anything that can push energy back. In contrast, a battery emulator or a regenerative supply is a different class of instrument.
What the listing says about connections
The input is 400 VAC, three phase, so the factory-installed option must match your site. Also, interfaces are LAN, USB, GPIB and analog. However, remote sensing and any series or parallel use need the Keysight instructions, because they depend on configuration.

High-voltage questions
How much current is available at 1000 V?
About 15 A. Divide the 15,000 W rating by 1000 V; the 30 A limit does not apply at that voltage.
Can I wire two units in series for a higher voltage?
Series and parallel use depend on configuration. Follow the Keysight instructions and ask Lost in HCM to confirm the quoted setup.
What should I check before I enable the output?
Check polarity, the overvoltage and current limits, cable ratings and insulation. Then record the final settings in the test procedure.
