The 120A DC ACR charging relay charges two batteries simultaneously via a shared alternator or a charger with only one output – and automatically disconnects them when the engine stops.
Features
- Closes as soon as one battery reaches the specified voltage value – both batteries are then fully charged
- Opens automatically when the voltage drops after the engine is switched off
- Connection for automatic disconnection when the engine starts and for control LED
