Guardian Digital Voltage Sensitive Relay (DVSR)

Digital Voltage Sensitive Relay (DVSR) / Automatic Charging Relay

VSR (Voltage Sensitive Relay) or ACR (Automatic Charging Relay) are automatically controlled switches that allow two batteries to be combined when charging, and to be isolated when not charging and current is draining from one of the batteries. When used with battery switches, VSR helps to reserve a fully charged battery at all time, avoid the dead battery and possibility of towing on the sea.

Features

Automatically combines two batteries when charging and isolates the two batteries when not charging.

• Robust Glass Fiber reinforced Nylon enclosure
• Built-in LED indication (ON when VSR engages)
• Port for remote LED indicating VSR status (LED not included)
• Surface or panel mount options provides flexibility when installing
• Optional Storage Mode allows zero power consumption when engine is off.
