Description
Which side of the 5000 W curve does your load sit on? The Keysight N8920A DC power supply offers up to 170 A, but only at the low end of its 80 V range. Because it is an N8900 Series autoranging system supply, it trades voltage for current along a 5000 W limit. It takes 208 VAC three phase. Lost in HCM lists it for rental, repair and sale in Vietnam.
Three operating points on a 5000 W budget
First, divide the rated power by the voltage you plan to use to find the current ceiling at that point. The figures below follow from the listed ratings, so check them against the Keysight data sheet.
| Output voltage | Approximate current ceiling |
|---|---|
| 80 V | 62.5 A |
| 48 V | About 104 A |
| About 29 V or lower | 170 A |
So the full 170 A is a low-voltage figure. If your device runs at 80 V, however, plan around roughly 62 A instead.

Low-voltage, high-current work
A 170 A ceiling suits assemblies that run at modest voltage and draw a lot of current. For example, it can feed converter inputs, DC-powered subsystems and controlled load tests. Electronics makers also use a programmable source like this for burn-in and repeated power-on checks.
High-current connections need an engineering review of conductor rating and joint resistance, so plan that review early. Then set the overvoltage and current limits from what the device under test needs, and record the final settings in the test procedure.
Ordering through Lost in HCM
Rent the Keysight N8920A DC power supply for a short project, or ask for a purchase quote if you need the current every week. Lost in HCM also takes repair intake, starting from the serial number and the symptoms. However, SMK Vietnam does not stock or service the unit.
Send your voltage and current pairs, dates and delivery city when you request a quote from Lost in HCM. You can also see other power supplies, read about the maker on keysight.com, or ask SMK Vietnam.
N8920A questions
How many amps can I draw at 48 V?
At 48 V, the 5000 W rating allows about 104 A. Only near 29 V or less does the full 170 A come into play, however.
Does it need three-phase power?
The listing shows 208 VAC, three phase, so ask for a photo of the label and the option list. The factory input option must match your site.
Does the photo show my exact unit?
No, because the photo shows the N8900 family. The quote then confirms the exact model and AC-input option.
