Working Principle
Converts AC/DC to regulated DC. In redundant mode, units share the load; if one fails, the other instantly takes over without voltage dip.
Installation Requirements
Provide adequate ventilation. Use properly sized wiring. Connect redundancy diode/oring module if required.
Usage Precautions
- Do not block air vents.
- Test redundancy switchover during maintenance.
- Replace if fault indicators persist.
