Keysight N8950A DC Power Supply, 1000 V, 30 A, 10 kW, N8900 Series

Description

A good kilovolt test starts as a written procedure, not as a turn of the knob. The Keysight N8950A DC power supply is an N8900 Series autoranging system that reaches 1000 V and 30 A within 10000 W. Lost in HCM lists it for rental and sale, and it arranges repair intake on request.

Write the procedure first

Before you request a quote, document the startup voltage, the current limits and the output order. Add the dwell time, the cooling plan and the pass-fail rule. Then another engineer can repeat the run, because the steps are on paper. Also record the final settings with each result.

If you plan to automate, then confirm the interface and driver behavior on a representative station. Interfaces on offer are LAN, USB, GPIB and analog.

Operating points on a 10 kW budget

Rated power limits the product of voltage and current, so divide 10000 W by the voltage to see the current ceiling.

So the full 30 A is not available at 1000 V. Therefore, check your own points against the Keysight data sheet.

What suits a Keysight N8950A DC power supply

• High-voltage DC inputs, such as those on converters and DC-powered assemblies.
• Endurance and screening runs, for example the same steps repeated overnight.
• Controlled load tests that need a stable source.

However, it remains a DC source. Do not assume it replaces a bidirectional battery emulator or a regenerative supply, and review inrush and shutdown before you connect.

Before it ships

The listed input is 400 VAC, three phase. Also, the factory-installed AC-input option must fit your installation, so ask for the label photo and the option list. At this voltage, insulation and guarding are part of the setup, and so is a check of polarity with the output off. Follow the Keysight user guide for the remaining steps.

Rental, purchase and repair

Rent the Keysight N8950A DC power supply for a validation campaign or a short production ramp. Buy it when the same source runs most weeks. In addition, Lost in HCM takes repair cases, and it asks for the serial number, symptoms and photos. However, SMK Vietnam only shows the listing.

So please request a quote from Lost in HCM with your dates, site and condition preference. For other models, browse power supplies. Final data lives on the Keysight website, and SMK Vietnam can help you reach the right team.

Questions on the N8950A

Can it give 30 A at 1000 V?

No. Rated power limits the output, so 1000 V allows about 10 A.

What should a test procedure record?

Startup voltage, current limits, output sequence, dwell time, cooling and pass-fail conditions.

Is new or used equipment possible?

Lost in HCM may quote new, used, refurbished or equivalent units, depending on condition and availability.
