Product Brief Introduction APOW‑02C is an internal switching‑power‑supply board for ABB ACS800 multi‑drive converter systems. It obtains energy from converter auxiliary windings and generates multiple isolated DC power rails for main control board, I/O boards and communication option boards inside multi‑drive cabinets.
Technical Specifications Input Power: Derived from converter transformer auxiliary winding Output Rails: +24 V DC, +15 V DC, ‑15 V DC, +5 V DC isolated outputs Built‑in Protection: Input fuse, output short‑circuit protection, over‑current protection, thermal shutdown Operating Temperature: 0 ℃ to +60 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5‑95 %, non‑condensing Mounting Type: Vertical plug‑in inside multi‑drive power‑unit rack Protection Class: IP20 Certifications: CE
Functional Features Generates multiple groups of isolated stable DC power supplies for internal control hardware. Integrated multi‑level hardware protection mechanisms for short‑circuit, over‑current and over‑temperature conditions. Supplies power for main‑control board, I/O terminals, communication cards and cabinet‑fan assemblies. Hardware fault‑status indicator LEDs show power‑board operating status. Plug‑in structure facilitates spare‑part replacement for multi‑drive cabinets.
Installation Requirements Insert APOW‑02C vertically into designated slot inside ACS800 multi‑drive power unit. Tighten fixing screws to prevent loosening under cabinet vibration. Confirm all input‑and‑output connectors are fully seated and locked. Ensure cabinet cooling‑airflow passes through the board area for heat dissipation. Carry out system protective‑earthing complying with drive‑system grounding specifications. Ambient operating environment must stay within rated temperature‑humidity ranges without condensation.
