Bep Dual Sense 125a Voltage Sensitive Relay Vsr 150a Intermittent, Continuous 2.75h X 2.75w 2d . Enjoy the benefits of fully charged engine starting batteries and deep cycle house batteries with one easy to install charging system. The Voltage Sensitive Relay VSR allows two batteries to be charged at the same time. When the engine is started and the start battery reaches 13.7 volts, the VSR engages, allowing two battery banks start and house to be charged simultaneously. When the voltage drops below 12.8 volts engine is stopped, the VSR disengages, separating the batteries. This system eliminates the possibility of draining the start battery and protects sensitive electronics powered by the house battery from harmful engine start up spikes. Dual sensing allows the relay to sense the voltage of both batteries, activating if either is receiving a charge. Designed for systems where a battery charger or second charging source is connected to the house battery.
