220A 12V - 24V Battery Protection - Victron Energy

Description

The BatteryProtect disconnects the battery from non-essential loads before it is completely discharged (which would damage it) or before it has insufficient power left to start the engine.

12/24 V auto sensing
The BatteryProtect automatically senses the system voltage.

Very easy programming
The BatteryProtect can be programmed to disconnect and connect at different voltage levels. The 7-segment display will show which setting has been chosen.

Special setting for Lithium-Ion batteries
In this mode, the BatteryProtect can be controlled by the VE-Bus BMS. Note: the BatteryProtect can also be used as a charge switch between a battery charger and a Li-ion battery.

Very low power consumption
This is an important feature for Lithium-Ion batteries, especially when used in low-voltage situations.

Over voltage protection
To prevent damage to loads that are sensitive to over voltage, the load will be disconnected if the DC voltage exceeds 16V and 32V respectively.

No relay, thus no spark
A relay is not used, but a MOSFET. This means that the BatteryProtect will not spark. This is suitable for use in potentially explosive environments.

Delayed alarm output
The alarm output is activated if the battery voltage drops below the preset disconnection voltage for more than 12 seconds. Starting the engine will therefore not trigger the alarm. The alarm output is a short-circuit-proof, open-collector output that is connected to the rail (negative), max. 50mA. The alarm output is typically used to activate a buzzer, an LED or a relay.

Load disconnect and reconnect delay
The load will be disconnected 90 seconds after the alarm is activated. If the battery voltage rises to the connection threshold during this period (when 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 risen above the preset load reconnect voltage.
