## Overview

The Durite 0-727-33 is a 12V 140amp intelligent split charge relay that automatically manages dual battery charging by sensing voltage changes. It activates at 13.3V to charge leisure batteries while protecting your starter battery by isolating it below 12.65V. Designed for camper vans, motorhomes, caravans, 4x4s, and boats, it supports dual sensing from engine, solar, or mains chargers, ensuring reliable power management without complex wiring.

## Description

Durite 0-727-33 Voltage Sense 140amp Intelligent RelayThe voltage sense relay simply detects the rise in voltage from you vehicles charging system when it exceeds 13.3v to allow you to charge your leisure battery(s) while your engine is running. Whe nyour engine is switched off and the battery voltage drops below 12.65v the relay will isolate your leisure battery(s) from your main starter battery so it does not drain your main starter battery and you will always be able to start your vehicle. All of the range of 140amp voltage sensitive relays are dualsensing meaning that if a charging voltage like through a mains charger or solar panel is applied to the leisure battery that exceeds the relay activation voltage of 13.3v it will activate the relay toallow this charging device to also maintain the starter battery.Additional InformationRelay activation voltage 13.3vRelay isolation Voltage 12.65vDuel sense operation Voltage sense systems are especially suited for modern vehicles asthis type of system does not need an ignition feed or any additionalwiring into your vehicle but for modern Intelligent smart charging vehicles with Euro cat 5&6 engines you may need to use a DC to DCcharger
