NAO Technologies Co MMPP-311-G001 Power Supply Repair Service

Professional diagnostic and board-level repair service for this NAO Technologies Co MMPP-311-G001 Power Supply.

The NAO Technologies Co MMPP‑311‑G001 is a 500 W switching power supply commonly used in Samsung Medison H60/MI96 ultrasound systems to deliver regulated DC rails to the imaging board. Typical failures include output voltage sag due to degraded electrolytic capacitors, overheating from fan or heat sink failure, and internal shorting of the MOSFET array that can trigger over‑current protection. First‑check diagnostics: verify 220 VAC input and correct polarity; measure all output rails with a calibrated multimeter for proper voltage and ripple; visually inspect for burnt components, swollen caps, or fan obstruction before proceeding to component replacement.
