VSR100 84 VSR200 DBC100 DBC150 DBS085K VSR100K A dual battery system (DBS) is recommended when needing to run powerful accessories, such as an inverter, fridge, or a tail gate loader on a truck, while the vehicle’s engine is turned off. A DBS allows accessories to run from an auxiliary battery that is independent of the starting battery, but is charged while the engine is running. A DBS ensures there is always enough power in the starting battery to start the vehicle. The auxiliary battery can be a different size and type to the main battery. DUAL BATTERY SYSTEMS POWER MANAGEMENT WHY ISOLATE YOUR BATTERIES? Features Solenoid Isolator Basic in its operation, the DBS085 is a heavy duty 85 Amp solenoid that offers a cost effective option for those looking for a reliable yet entry level dual battery management system. Available as a comprehensive kit, the DBS085 offers easy installation and includes a convenient in-cab ignition isolation switch that enables the user total control of the charging process. DBC100K Voltage Sensitive Relay Suitable for a wide variety of 12V DC applications, the VSR units sense the input voltage generated and automatically connect/ disconnect the appliance or circuit at pre-set voltages. Fully sealed to IP66 and surge protected, the VSR units feature a manual override function allowing the user to bypass the automatic voltage sensor enabling the solenoid to be engaged below the set voltages. VSR units are ideal for dual battery setups as they enable the batteries to be paralleled for high power usage, eg jumpstarting or winching.

This voltage (13.8V) under-charges and reduces the life of the deep cycle battery. The 3 stage charge delivered by the DC/DC charger inputs a full 14.4V charge ensuring increased performance and life of your deep cycle battery. The first stage (bulk) charges the battery faster while the second stage (absorption) ensures the battery is thoroughly charged. The final stage (float) maintains the battery ready for use and can be left connected indefinitely. 94 The DC/DC charger overcomes the problem of voltage drop associated with long cables commonly used with auxiliary battery installations. By ‘stepping up’ the dropped voltage using ‘switchmode’ charging technology the DC20 delivers a full 3 stage charge to your auxiliary battery. AUX BATTERY AUX BATTERY MAIN BATTERY DC/DC CHARGER DC/DC CHARGER: the voltage is stepped up to 14.4V as part of the 3 stage charge DC/DC CHARGER ALTERNATOR’S CHARGE VOLTAGE: an alternator typically produces 13.8V which is insufficient for charging deep cycle batteries VOLTAGE DROP: as a result of long cable lengths voltage may drop as low as 11.8V 3 STAGE AUTOMATIC 12V to 12V, 20 Amp Battery Charger POWER MANAGEMENT HOW IT WORKS Features DC/DC CHARGER Turns on with Ignition The DC20 can be wired to the vehicle’s ignition allowing it to operate only when the ignition is turned on. AUX BATTERY L.E.D display Indicator lights on the front panel provide a quick reference for the charger’s status. 3-Stage Charging Voltage Boosting Using electronic control, the charger delivers 3 stage charging resulting in a faster and more powerful charge. MAIN BATTERY DC/DC CHARGER Switchmode technology converts your vehicle’s 12VDC alternator power up to 14.4VDC for a 100% charge.
