12V 140A battery isolator relay set for 2 batteries with connection cable

The isolation relay can charge two batteries simultaneously.

Function of the isolation relay:

When the engine is running and the voltage exceeds 13.3 volts, the isolation relay closes and the leisure battery is charged in addition to the starter battery. When the engine is switched off, the system voltage drops below 12.8 volts, and the isolation relay disconnects the starter battery from the leisure battery. This system prevents the starter battery from discharging and protects sensitive electronics connected to the leisure battery from voltage spikes that can occur when starting the engine.

Product Features:

• No voltage drop due to high-quality components
• Maximum current rating: 140A
• Sensor for both batteries
• Fully automatic control
• With surge protection
• Simple three-wire connection to the battery. The existing alternator wiring does not need to be bypassed.
• LED display
• Connection via tinned M6 screw bolts.
• Switch-on voltage / start of charging: 13.3V +0.1
• Cut-off voltage / end of charging: 12.8V +0.15
• No alternator connection (D+) is required.
• The electronic module automatically detects when the alternator starts charging.
