[ APC Microprocessor Fault Detection ] │ ┌────────────────────────┼────────────────────────┐ ▼ ▼ ▼ [Battery Malfunction] [Internal Relay Weld] [Firmware Corruption] - Age/voltage drop - Stuck contacts - Desynced logic - False RBC disconnect - High inverter output - Outdated version 1. Battery Malfunction or False Disconnects
In double-conversion online UPS systems, the inverter runs constantly to convert DC power into clean AC power. Over time, heat and stress can cause components like Insulated-Gate Bipolar Transistors (IGBTs) or internal capacitors to fail. 3. Faulty or Completely Depleted Batteries Major harmonic distortion or input frequency anomalies have
