Description
When a high-voltage supply misbehaves, the fault is not always inside the supply. The Keysight N8929A DC power supply is an N8900 Series autoranging unit rated 750 V, 40 A and 10000 W, so a careful intake saves time. It takes 208 VAC three phase. Lost in HCM lists it for rental, repair and sale in Vietnam.
Repair intake for the Keysight N8929A DC power supply
Stop using the unit if you see smoke, liquid, damaged insulation, abnormal heating or unsafe behavior. Then send Lost in HCM the model and serial number, the symptoms and any error messages. Also include self-test results, photographs and the condition of the connectors.
Next, add the firmware, the installed options, recent events and the service history. Finally, say which known-good accessories you already tried. This intake helps separate an instrument fault from cables, fixtures, software, grounding, facility power or the device under test.
Repair and calibration are separate
Functional repair and traceable calibration are separate deliverables, so say which one you need. For example, a unit can work again and still need calibration documents for your quality system. Tell Lost in HCM which of the two you want quoted.

Need it only for a while?
If a unit goes down mid-project, a rental can bridge the gap. Rent the Keysight N8929A DC power supply for a validation campaign, then ask about a purchase if you keep using it. At 750 V the 10000 W rating allows about 13 A, while the full 40 A needs about 250 V or lower.
To begin, request a quote from Lost in HCM. You can also see more power supplies, visit Keysight, or contact SMK Vietnam. However, SMK does not stock, rent or repair the unit itself.
N8929A questions
What should I photograph for a repair request?
Photograph the label, the connectors and any visible damage. Also capture the error messages and the self-test result.
Does repair include calibration?
No, because functional repair and traceable calibration are separate deliverables. So tell Lost in HCM which one you need.
What does the 10000 W limit allow at 750 V?
Around 13 A, which is as far as 10000 W stretches at 750 V. So the full 40 A needs about 250 V or less.
