Description
Start with the voltage, because it decides which 15 kW source fits your bench. The Keysight N8955A DC power supply covers up to 750 V and 60 A as an N8900 Series autoranging system. Lost in HCM lists it for rental and sale.
Voltage first, then current
This model sits at 750 V and 60 A, and rated power limits what you can draw at any one time. Run it at 750 V and rated power allows 20 A. Reach the full 60 A by dropping to 250 V or less. So a test that holds 600 V, for example, can draw about 25 A.
Sketch your own operating points on that envelope before you book. Also note the startup voltage, the current limit and the longest run.
Test stations that suit 750 V
Mid-range DC inputs are common on converter and inverter hardware. In addition, a programmable source of this class works well for production screening and burn-in. Write down the startup voltage, the current limits, the output order, the dwell time and the pass-fail rule for each step. Then try the automation on one station, because driver behavior can differ from what you expect.
You can also use it for controlled load work on DC-powered assemblies. Because it is a DC source, check the energy flow first if your device can feed power back. Do not assume it stands in for a battery emulator or a regenerative supply.
Before it arrives
The source lists three-phase 400 VAC input, and the factory-installed option must match your site. Ask Lost in HCM for the label photo and the option list. Interfaces include LAN, USB, GPIB and analog.
Higher-voltage setups call for proper insulation and guarding. Choose overvoltage and current limits from the device under test, then verify polarity before you enable the output. Treat parallel or series use as a configuration that needs the Keysight instructions.
Request the Keysight N8955A DC power supply
Lost in HCM rents, sells and arranges service on request, while SMK Vietnam only hosts the listing. A rental of the Keysight N8955A DC power supply fits a validation campaign or a short production ramp. Buying makes sense when the source runs every week. To start, request a quote from Lost in HCM and list your dates, duty cycle and site. For other models, see our power supplies or contact SMK Vietnam. Final data sits on the Keysight site.
Questions about the N8955A
How much current can I draw at 600 V?
About 25 A. Divide the 15,000 W rating by the voltage, then stay under the 60 A limit.
What should I send with a rental request?
Send the dates, duty cycle, site, delivery city, interfaces and accessories. Add the voltage and current pairs you plan to run.
Can I use it as a battery emulator?
Do not assume so. It is a DC source, so confirm energy flow and shutdown needs for your device first.
