Contour Voltage Sensitive Relay, 24 Volt to 300 Amp

DESCRIPTION

Twin battery charging made easy!

A VSR designed for larger systems with all of the features of the 100 amp models, with the added benefit of enabling push button control from the steering station to parallel two batteries in the event of a low battery upon starting. The unit is dual sensing allowing it to sense the start batteries and the house batteries enabling a single output battery charger to be connected to the house batteries. This parallels the start batteries when the house reaches 13.7 volts.

The parallelling function can be operated via a momentary button on the dash. Pushing the button will parallel the two batteries for a period of ten minutes, then revert to standard VSR mode. If the preset 13.7 volts has been reached it will continue to charge both batteries, if 13.7 volts has not been reached, it will prioritise the charging to the start battery only until the starting battery has reached this potential, whereupon it will revert to charging the two batteries together.

When engines are restarted next time the VSR will have reverted to it's normal mode i.e., starting from the dedicated start battery only. The unit may also be used as a parallelling solenoid by disengaging the voltage sensitive function. There is also a manual control switch built in to select Off (OFF)/VSR On (AUTO) or Battery Parallel (ON).
