              What it actually does

              This board is the internal “low-voltage brain power supply” of ABB drive systems.

              It:

              • Converts incoming supply into multiple stable DC rails
              • Powers control CPU, logic boards, and signal interfaces
              • Filters noise from high-power drive circuits
              • Stabilizes system operation under load fluctuation
              • Protects control electronics from voltage spikes

              ---

              System Role (Simple)

              Main AC/DC supply
              → rectification & filtering
              → SDCS-POW-1 board (this module)
              → generates low-voltage rails (+5V / ±15V / 24V)
              → powers drive control electronics

              ---

              Precautions

              • Must match correct ABB drive system model (DCS compatibility critical)
              • High-voltage capacitors may retain charge after shutdown
              • Sensitive electronic board → ESD protection required
              • Replacement should be done with power fully discharged
              • Incorrect installation may damage drive control system
