Okuma BL-D 50A Power Supply

The Okuma BL‑D 50A is a 50 A brushless servo drive power module used with OSP5000/5020 control systems. Common failure modes include capacitor degradation or rupture on the high‑voltage side, fuse blowouts in the input/output paths, and overheating of the internal MOSFET array due to poor ventilation or thermal overload. First‑check diagnostics should verify that the 48 V DC supply is within spec, inspect all electrolytic capacitors for bulging or leakage, test the main fuses and measure output current under load; a visual inspection of the PCB for burn marks or cracked traces will often reveal the root cause.[oss-gpt-20b] Post Comment
