Product description

● The Digital Voltage Sensing Relay (VSR) allows the charging of a second battery (for example services) from a single source load. When the engine is started and the voltage at the engine battery reaches 60% charge, the VSR into operation also allows charging the second battery. When the battery voltage drops engine (the engine stops for example.) the VSR disconnects and isolates the 2 batteries eliminating the possibility that the battery is discharged dle engine.

● Protect sensitive electronic devices connected to the battery service possible damage caused by a surge in engine start.

● Easy installation with 3-wire connection, leave intact alternator wiring.

● No voltage drop as blocking diodes.

● Start protected.

● can be mounted flush or surface.

● 12 -24 V

● 140Amp
