Product Details
The Digital Voltage Sensing Relay (DVSR) streamlines the process of charging a secondary battery bank from a single power source. Once the voltage of the primary battery rises to a set threshold, the DVSR activates, allowing charge to flow to the second battery. When charging stops and voltage drops, the relay automatically disconnects the batteries—protecting the starting battery from being drained. Built with advanced digital circuitry, the DVSR ensures reliable performance with minimal power usage.
Key Features Enables safe charging of multiple battery banks from a single source (alternator or charger)
Prioritises charging of starting batteries before engaging auxiliary banks
Prevents start battery from being discharged by house loads
Shields sensitive electronics from starter motor voltage spikes
Easy 3-wire installation—no modification to alternator wiring needed
Zero voltage drop compared to traditional diode isolators
