AC Power Source Repair

The AC Power Source is a programmable power supply – it holds a commanded voltage or current under whatever load the device under test presents, and switches between constant-voltage and constant-current regulation as that load changes. The output stage does the work, and it is where the heat and the wear concentrate.

The AC Power Source is repaired at June Company by technicians who work on this class of instrument daily, for test engineers, production test departments, R&D laboratories, and equipment manufacturers. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.

Common AC Power Source problems we fix

Output stage or pass-element failure.
Current limit not holding at the set value.
Output relay not switching.
Cooling fan or thermal shutdown.
Internal power supply faults.
GPIB, LAN, USB or remote-control faults – which breaks automated test sequences while the instrument still works from the front panel.
Display, keypad or front-panel faults.
Output voltage or current out of tolerance under load – a supply can read correct on its own display while delivering something else to the load – readback and actual output are separate circuits and they drift separately.
Will not regulate, or oscillates between CV and CC.
Excessive ripple or noise on the output – invisible on the front panel and capable of corrupting whatever is being powered.

FAQs

What if it is not economical to repair? We tell you in the quote. The evaluation is free and there is no obligation to proceed.

Output is unstable under a changing load. Repairable? Yes. That usually points at the regulation loop or the CV/CC crossover rather than the output devices themselves.

Every repair carries a 90-day parts-and-labor warranty, with a firm quote before any work begins. Email us or submit a service request.
