Cable Sizes and Fuses
Cables used at each positive terminal must be of sufficient rating, under sized cables would affect the performance of the unit and
shortens the life span. Wires connected to control or signal ports carry less than 0.5 Amp.
Fuses or circuit breakers of appropriate rating must be installed at positive terminal of the house battery and main battery. These
fuses are for the safety and protection of the vehicle’s electrical system in case of a short to the negative ground.
Using with inductive load
When inductive load (such as DC motor, solenoid & etc.) is directly connected to isolator terminal, a diode (400V 3A, bundle
with unit) must be connected across the load.
1. General description
This advanced programmable battery protector is designed to protect all types batteries from over discharged and also safe guard
your load .
The limited settings of ordinary battery protector cannot cover all discharging conditions because of large combinations of battery
type, capacity, versus types of load, size of load and loading conditions such as slow bleeding load or short large starting load such
as high inductive or capacitive load .Unintended or unexpected "chattering" quick on-off operations, and premature or belated on
off are the common defects which sometimes not only harmful to your valuable battery but also to the load.
The reliable and efficient Mosfet switching has minimal voltage loss resulting much less generated heat than diode based
protectors. Microprocessor Controlled circuit provides accurate monitoring, finer tuning of voltage, delay timer set points and
more fail safe protection with diagnostic display.
2. Advanced Features
●Alert Voltage:
The additional Alert Voltage setting is to monitor the main battery voltage even when the unit in isolated mode and when the
main battery voltage drops below the set Alert Voltage, the Remote LED Module will out slow flashes to alert end user.
●Remote LED Module with Over-Ride
With the supplied Remote LED module w Over-Ride accessory, end user is constantly informed about the status of the
Protector whether it is in Connection Mode, Isolation Mode, Main Battery is above or at Alert low level and Protector is in
Protection Mode.
●Selectable 12V or 24V system
●Selectable Ignition Control
●Wide range of programmable threshold voltages (connect, isolate, alert) with high resolution and respective delay time.
●Monitoring of Main battery voltage.
3. Intended Applications:
To protect starting, house or site batteries and equipment for caravan, SUV, boat, with DC loads such as DC motors, inverter,
communication equipment, fridge, and etc. against damage, and over discharging.
When battery is connected to a charging source such as solar, wind, battery charger, it can conserve the battery power by allowing
the load to draw power from the charging dc source when the battery is full according to your presets of LVR and LVD.
