International Power Sources PU30-10S Power Supply Repair Service

Professional diagnostic and board-level repair service for this International Power Sources PU30-10S Power Supply.

The PU30‑10S is a compact 30 W switching power supply from International Power Sources, designed for industrial control and PLC applications with universal input (85–264 VAC) and a single 12 VDC output. Common failure points include the internal MOSFET array or inductor winding degradation, which often manifest as overheating, voltage sag, or audible noise; the EMI filter can also fail, causing ripple on the output. Initial checks should verify input voltage and current with a multimeter, confirm the output rail against spec while monitoring for excess heat, and inspect the PCB for burnt components or cracked solder joints before proceeding to component replacement.
