Material and Structure
Housing: metal.
PCB mainboard: FR4.
Power devices: switching power supply modules.
Capacitors: electrolytic.
Connector: backplane gold finger (edge connector).
Heat dissipation: metal heat conduction.
Operating Principle
AC input undergoes EMI filtering and rectification, followed by high-frequency switching conversion, isolated step-down, and rectification to produce multiple DC outputs. These are delivered through backplane gold-finger connectors to the control cards. Monitoring circuitry performs protective action upon abnormality.
Installation Requirements
Power off before inserting into the rack slot.
Verify input voltage matches the AC supply.
Ensure rack grounding.
Confirm output voltage after power-up.
Lock the card securely in place.
Precautions
Confirm redundancy before online replacement.
Never connect the AC voltage incorrectly.
Ensure output polarity is correct.
Store spare parts in a moisture-proof environment.
Periodically inspect output.
