Mitsubishi Electric MDS-A_CV-260 Power Supply
 |
Mitsubishi Electric MDS‑A_CV‑260 is a high‑current DC power module used to supply spindle drives in CNC systems, rated for 115 A and up to 26 kW output. Common failure modes on this class of units include burned fuses or internal protection relays tripping, insulation degradation leading to shorted output windings, and thermal overload from prolonged high‑current operation. First‑check diagnostics: verify the incoming 3‑phase AC supply (200–230 V) with a multimeter; inspect all fuses and protection contacts for continuity; visually examine the module for burn marks or loose connections, and review any error codes logged by the spindle controller that reference power supply faults.[oss-gpt-20b] |
