Sorensen DCR-80-125T control unit Repair Service

Professional diagnostic and board-level repair service for this Sorensen DCR-80-125T control unit.

The Sorensen DCR‑80‑125T is a high‑power programmable DC power supply rated at 80 V/125 A (10 kW) with EMI protection and full remote control/monitoring. Common failure modes include over‑voltage protection (OVP) shutdown, phase‑loss detection, thermal over‑temperature shutdown, and firmware or communication errors that disable output regulation. Initial diagnostics should verify the AC line voltage and phase continuity, confirm the unit’s status LEDs for OVP or phase‑loss indications, and measure the output voltage/current under load to ensure proper regulation. Inspect the PCB for burn marks, loose solder joints, or damaged components, then test the remote control interface and firmware integrity before proceeding with component replacement. Post Comment
