Description
Six hundred volts is a number you read twice, so plan carefully. The Keysight N8742A DC power supply has one output of 600 V and 5.5 A, rated 3300 W, and it sits in the N8700 Series of programmable system supplies. Lost in HCM lists it for rental and sale in Vietnam, and it arranges repair intake on request.
Respect the voltage first
At 600 V the setup needs appropriate insulation and guarding. Rate the cables and the terminals for that voltage, then follow the discharge procedure in the Keysight user guide. Have a qualified engineer review the plan before the first power-up. In addition, check polarity before you enable the output.
The current is modest, however. Since 600 V times 5.5 A equals 3300 W, the corner point matches the rating, but real test points will use less.
Repair intake and calibration are different jobs
A functional repair and a traceable calibration are separate deliverables. So say which one you need when you write to Lost in HCM. For a repair, first send the model and serial number, the symptoms, any error messages and the self-test results. Photos, firmware and installed options also help.
Stop using a unit that shows smoke, liquid ingress, damaged insulation or abnormal heating. Then keep it off until a technician has looked at it.

Rent, buy or repair
Rent the Keysight N8742A DC power supply for a high-voltage trial or a temporary capacity boost. Ask for a purchase quote when the work continues, because a long project justifies owning one. For any route, request a quote from Lost in HCM and name the AC input at your site. More units appear in the power supplies category, while the Keysight website covers the maker. For listing questions, contact SMK Vietnam as well.
N8742A questions
What should I send for a repair evaluation?
Send the model, the serial number, the symptoms, error messages, self-test results, photos, firmware, installed options and any service history, so the intake team can start at once.
Is calibration part of a repair?
Not automatically, because a repair and a traceable calibration are separate deliverables. So ask for each one you need.
Can I keep using a unit with damaged insulation?
No. Stop using any unit that shows damaged insulation, smoke, liquid ingress or abnormal heating, and then have it checked.
