Working Principle AC230 V after EMI filtering and rectification feeds a switching converter, isolated and stepped down to DC24 V through backplane gold fingers. Dual supplies current-share. Monitoring detects voltage; abnormalities trigger LEDs and relay.
Installation Requirements
- Insert power slot with power off
- Connect AC230 V
- Dual supplies on independent AC
- Rack grounding
- Temperature -20 °C to +70 °C
- Verify output after power-up
- Redundancy pairing
Precautions
- Confirm redundancy before online replacement
- AC voltage must not be wrong
- DC polarity correct
- Store spares in anti-static moisture-proof packaging
- Periodically check output voltage
- Confirm CPU power status after replacement
