Sorenser DCR 150-70A power supply Repair Service

Professional diagnostic and board-level repair service for this Sorenser DCR 150-70A power supply.

The Sorensen DCR 150‑70A is a high‑current (up to 70 A) programmable DC power supply rated at 0–150 V with ±0.10% voltage regulation and ±140 mA current regulation, commonly used in industrial test rigs or motor drive conditioning. Typical failure modes for this class of units include SCR driver burnout, capacitor degradation on the output filtering stage, overheating of the internal heatsink due to inadequate ventilation, and control board faults such as damaged op‑amps or microcontroller resets. Initial checks should verify that the input AC is within spec and that the PSU’s fan and heat sink are clear; then confirm the output voltage/current with a calibrated multimeter while monitoring for ripple spikes; finally inspect the main capacitors and SCR driver ICs for discoloration, bulging, or burn marks.
