Integrated power designs 115-4000 power supply Repair Service

Professional diagnostic and board-level repair service for this Integrated power designs 115-4000 power supply.

Integrated Power Designs SRW‑115‑4000 is a compact, high‑efficiency AC‑to‑DC switching power supply rated at 400 W, commonly used in industrial control cabinets and test equipment. Common failure points include the input rectifier bridge, main output MOSFETs, and the feedback network (sense resistors or optocoupler); overheating can also damage the internal capacitors and heat sink. First‑check diagnostics: verify that the unit receives proper 120/240 VAC with a multimeter; inspect for visible burn marks, swollen electrolytics, or loose connections on the PCB; confirm output voltage and ripple using an oscilloscope while monitoring the current draw; and review any error codes or LED status indicators that may point to over‑temperature or undervoltage lockout.
