1. Cooling Device:

o Including radiators (aluminum extruded fin), fans (forced air cooling), metal enclosures, etc.

o The rectification process generates heat loss, effective heat dissipation is crucial for ensuring the module operates stably and reliably over the long term.

　　2. Shell and Interface:

Provide physical protection and electrical isolation.

Clearly label input (AC), output (DC) terminals, and any control signal interfaces, status indicators, etc.
