Product informatie
The BatteryProtect disconnects the battery from non-essential loads before it is completely discharged (which would damage the battery) or before there is insufficient power left to start the engine.
Automatic 12/24V detection
The BatteryProtect automatically detects the system voltage.
Easy programming
The BatteryProtect can be set to engage/disengage at different voltages. The 7-segment display shows the selected setting.
A special setting for lithium-ion batteries
In this mode, the BatteryProtect can be controlled by the VE.Bus BMS. Please note: the BatteryProtect can also be used as a charge disconnector between a battery charger and a Li-ion battery. See wiring diagram in the manual.
Ultra-low current consumption
This is important in the case of lithium-ion batteries, especially after a low-voltage shutdown.
Overvoltage protection
To prevent damage to sensitive loads due to overvoltage, the load is disconnected as soon as the DC voltage exceeds 16V or 32V respectively.
Ignition Protected
No relays, but MOSFET switches and thus no sparks.
Delayed alarm
The alarm is triggered if the battery voltage drops below the preset disconnection level for more than 12 seconds. Starting the engine therefore will not activate the alarm. The alarm output is a short-circuit-proof open collector output connected to the negative (minus) rail, max. current 50mA. The alarm output is generally used to activate the buzzer, an LED or relay.
Delayed load disconnection and delayed reconnection
The load is disconnected 90 seconds after the alarm has been activated. If the battery voltage rises again to the connection threshold within this time frame (e.g. after the engine has started), the load will not be disconnected. The load will be reconnected 30 seconds after the battery voltage has risen to more than the preset reconnection voltage.
The battery protector is not designed for counter-current from charging devices.
