Product Overview: The PU110-31A is a 110W triple-output open-frame AC-DC power supply manufactured by International Power Sources (now part of XP Power). It provides three independently regulated DC outputs and is commonly used in CNC controllers, such as the Anilam 3300 found in Chevalier knee mills and similar industrial machinery. The open chassis design allows for direct PCB mounting in space-constrained equipment. Key features include multiple output voltages configurable for different system requirements and suitable power density for embedded control applications.

Power supplies are tested with a minimum 4-hour burn-in, under load. The PU110 series contains about 20 different supplies. Send in your unit for our technicians to evaluate and repair.
Common Failures
Common issues with this power supply unit include a no power output condition despite input power being present. Typical causes include a defective startup resistor, corrosion due to conductive glue in heated areas, and cracked solder joints on power resistors.
Repair Approach
The repair process typically involves replacing defective components such as the startup resistor and performing preventative maintenance by upgrading or replacing electrolytic capacitors. Connections, especially those with cracked solder joints, are resoldered to restore reliable operation.
Testing & Quality
Comprehensive diagnostic testing is conducted, including Huntron and ohmmeter testing of key components such as the switching MOSFET, opto-isolator, and transformer coils. Burn-in tests with load are performed to verify stability, and all repairs are verified with a final inspection to confirm output voltage settings meet customer specifications.
