1. Simple installation, medium-sized voltage-sensing split charging relay system for safely charging 75A to 120A leisure batteries.
2. The voltage sensing relay only detects the voltage rise in the vehicle charging system, allowing you to charge the recreational battery while the engine is running.
3. When the engine is off, the relay isolates your recreational battery from the main starter battery. So it won't drain the main starter battery and you will always be able to start the vehicle.
4. Suitable for camper vans, RVs, 4x4s, Day Vans, mobile workshops, cars or boats.
5. Increase solder joints to enhance heat dissipation
6. Continuous current: 140A
7. Current (MAX): 160A
8. Current consumption - charging: 280mA
9. Current consumption - standby: 8mA
10. Disengagement delay: 5-10 seconds
11. Recommended fuse: 80Amp
12. Power stud: M6 stainless steel
13. Surge Protection: Built-in
