Second vehicle Battery separator SMART SOLENOID
$120.00
Catalog #52-89
SGC Battery Separator is designed for use when an auxiliary battery is used in addition to the main battery and charging system of a vehicle. This unit protects the main battery and the auxiliary battery by continually monitoring the status of each batteries charge potential. It then has two basic operational characteristics, as follows: Assist in Engine Starting: When the starter is activated, the Battery Separator compares the voltage of both battery banks. If the chassis' battery is lower than the auxiliary battery bank, the Battery Separator will engage, allowing the auxiliary battery bank to aid in vehicle starting. The start signal must be at least three volts for this operation to occur. Protecting the Charging System from Excessive Drain from either Battery: The Battery Seprator monitors the battery system to determine if the batteries are being charged. If the drain on the charging system by the auxiliary or main battery bank reduces the system voltage below 12.4-12.9 volts, the Battery Separator will disconnect the battery banks from each other until either one is charged.
A delay function has been incorporated in the control circuit to prevent the Battery Separator from reacting to momentary voltage fluctuations and chattering.
