Product Overview: The SQM150-1222-5-A is a multiple output switching power supply from Switching Systems International's SQM Series. It provides regulated DC voltages at +5VDC, +12VDC, and -22VDC outputs for industrial control applications. The +5VDC output is the regulating output and requires a minimum 1A load (approximately 5 ohms) to maintain proper regulation across all outputs. Without sufficient load on the +5V rail, the supply enters power fail detect mode and shuts down all outputs. Common applications include machine tool controls and paper processing equipment. Key components include a switching controller operating up to 100kHz and protection circuitry with inrush limiting.

Common Failures
Frequent issues include low output voltage or voltage drop, which may be related to component wear such as electrolytic capacitors or inrush thermistors. Cracked or cold solder joints on primary and output connections have also been observed and can contribute to intermittent performance.
Repair Approach
Our team evaluates each unit individually. Repairs may involve replacing worn capacitors, thermistors, or other failed components identified during evaluation. Solder joints are inspected and re-worked as needed. Cleaning and reapplication of thermal compound may also be performed to support proper heat management.
Testing & Quality
Once repairs are complete, we perform comprehensive testing under load to verify that the unit regulates outputs as expected. Additional inspections and functional tests are conducted to confirm performance and reliability before the unit is released.
