12/24V auto 80A voltage threshold relay

This waterproof relay is fully automatic and does not require a control signal to switch off. As soon as the voltage of the engine battery reaches 13.3V, the relay will switch on and connect the starter battery and the service battery. Similarly, as soon as the voltage of the engine battery drops below 12.9V, the relay will decouple the two batteries as long as it means that the engine is stopped or that a consumer (windlass for example) is using current on the starter battery and that it is preferable to isolate.

This more advanced relay has the advantage of being easier to install than a relay with a control signal

Features:

• Power: 12V or 24V (automatic detection) / 80A
• Dimensions / Weight: 140*190*40 mm / 0.1 kg
• Waterproof relays (IP68) with gold-plated connector to support the rated load.
• Start protection: The relay is deactivated during motor start to prevent damage.
• Protection system to limit damage during disconnection when the relay is loaded.
• Automatic relay: automatically switches on according to the voltage of the engine battery.
• Additional function allowing the relay to be switched on in both directions (as soon as the voltage has reached the threshold determined on one of the terminals.
• Configurable connection and disconnection voltage.
• Compatible with 12 and 24V.
• Progressive disconnection algorithm to ensure recharging even when the voltage difference between the battery banks is significant.
