This relay allows simultaneous charging of two batteries with just one alternator.
When the engine starts, the Voltage Sensitive Relay remains open until the starter battery reaches 13.7 / 27 V.
At this point, the Voltage Sensitive Relay closes the contact and simultaneously charges the 2 batteries.
When the engine stops and the voltage drops below 12.8 / 25.2 V, the Voltage Sensitive Relay opens the contact and separates the two batteries, thus preventing the discharge of the wrong battery and also avoiding current spikes harmful to the onboard electronics when the engine is restarted.
Protects the starter battery from discharging due to onboard services.
No voltage drop.
No current absorption in standby mode.
Easy to install without altering the alternator wiring.
Automatic selection 12/24 V.
