AL-PT200

Alfatronix POWERTECTOR low voltage battery disconnect guard 200A is a battery protection device designed to disconnect a connected load when supply voltage falls too low. It is intended for use in 12V or 24V DC systems, helping to protect batteries from deep discharge where low-voltage cut-off is required.

Typical applications

Battery disconnect guards are commonly used in vehicles, mobile equipment and other DC installations where preserving battery condition is important. They are typically fitted between the battery supply and the load so that connected equipment is isolated before the battery is drawn down excessively.

This type of device can be useful in leisure, commercial and specialist electrical systems, but the exact installation depends on the system design and the load being protected. Buyers should check that the required operating voltage, current capacity and low-voltage disconnect behaviour suit their application.

Choosing the right battery disconnect guard

For a low voltage battery disconnect guard, the key checks are the system voltage, the continuous current demand and the point at which disconnect and reconnection occur. The 200A rating makes this unit suitable only where that level of current capacity is appropriate for the installation.

If you are replacing an existing guard, compare the voltage rating, current rating and terminal or wiring requirements with the original unit. If the application uses sensitive electronics, confirm that the disconnect characteristics are compatible with the equipment being protected.

Handling and installation

Battery protection devices should be installed according to the system wiring layout and the manufacturer’s instructions. They are normally selected to match the load path and protection requirements of the circuit, rather than by physical size alone.
