Alcatel SMR-1000W-48-20 Power Supply Repair Service

Professional diagnostic and board-level repair service for this Alcatel SMR-1000W-48-20 Power Supply.

The Alcatel SMR‑1000W‑48‑20 is a 1 kW industrial power supply delivering 48 V at up to 20 A, typically used as the main DC source for motor drives or control panels. Common failure modes in this class include overheating of the internal rectifier bridge, degradation of the output filter capacitors, and failure of the built‑in over‑current protection circuitry. First‑check steps: verify input AC voltage and ripple, measure the 48 V output under no load and with a dummy load, inspect for visible signs of burn or component swelling, and review any error logs from the host controller for power‑supply related fault codes.
