Blue Sea BS 7615 Automatic Timer Disconnect (ATD) disconnects the battery and shuts down systems to prevent excessive battery discharge.
Timer Disconnect
- Relay connects the battery to consumers via a 12V signal
- As soon as the signal ends, the timer is activated and disconnects the consumers after the set time expires
- Timer adjustable from 15 minutes to 4 hours
Low Voltage Disconnect
- Detects low battery voltage and automatically disconnects consumers to prevent deep discharge
- Can be combined with the timer and disconnects consumers before the timer expires in case of low charge
Automatic Charging Relay
- Automatically combines two batteries for charging and isolates them during discharge
- Single-sided sensor monitors only the starter battery's charge
- Ideal for AGM auxiliary batteries or auxiliary batteries with much higher capacity than the starter battery
Solenoid
- 12V signal instantly connects or disconnects the battery to/from the consumers
