5. Konfiguracja i instalacja
Follow these steps for proper installation of the DC-DC Step-Down Converter:
- Przygotuj się do instalacji:
- Przed rozpoczęciem instalacji należy upewnić się, że wszystkie źródła zasilania są odłączone.
- Identify a suitable mounting location for the converter. It should be secure, allow for adequate airflow, and be protected from direct physical impact.
- Połączenia elektryczne:
The converter features a four-wire connection system:
- Przewody wejściowe: Red (+) and Black (-) wires connect to your 36V/48V DC power source (e.g., battery). The red wire includes an inline fuse for protection.
- Przewody wyjściowe: Yellow (+) and Black (-) wires connect to your 12V DC load (e.g., LED lights, audio system).
Procedura połączenia:
- Połącz Red (+) input wire of the converter to the positive terminal of your 36V/48V battery.
- Połącz Black (-) input wire of the converter to the negative terminal of your 36V/48V battery.
- Połącz Yellow (+) output wire of the converter to the positive terminal of your 12V device.
- Połącz Black (-) output wire of the converter to the negative terminal of your 12V device.
