BatteryProtect 48V

BatteryProtect 48V
BatteryProtect 48V-100A
With 7-segment LED display: easy to set up
The BatteryProtect disconnects the battery from non-essential loads before it is completely discharged (which
would damage the battery) or before it has insufficient power left to crank the engine.
Programming made easy
The BatteryProtect can be set to engage / disengage at several different voltages.
The seven segment display will indicate which setting has been chosen.
A special setting for Li-ion batteries
In this mode the Battery Protect can be controlled by the VE.Bus BMS.
Ultra-low current consumption
This is important in case of Li-ion batteries, especially after low voltage shutdown.
Please see our Li-ion battery datasheet and the VE.Bus BMS manual for more information.
Over voltage protection
To prevent damage to sensitive loads due to over voltage, the load is disconnected whenever the DC voltage
exceeds 64 V.
BatteryProtect BP 48-100
Ignition proof
No relays but MOSFET switches, and therefore no sparks.
Delayed alarm output
The alarm output is activated if the battery voltage drops below the preset disconnect level during more than 12
seconds. Starting the engine will therefore not activate the alarm. The alarm output is a short circuit proof open
collector output to the negative (minus) rail, max. current 50 mA. The alarm output is typically used to activate a
buzzer, LED or relay.
Connector with preassembled DC
minus cable (included)
Delayed load disconnect and delayed reconnect
The load will be disconnected 90 seconds after the alarm has been activated. If the battery voltage increases
again to the connect threshold within this time period (after the engine has been started for example), the load
will not be disconnected.
The load will be reconnected 30 seconds after the battery voltage has increased to more than the preset
reconnect voltage.
