Discharging your battery to very low levels can cause irreversible damage, reducing its performance and ability to hold charge. These universal programmable battery guards from power conversion specialist Samlex prevent this excessive discharge by disconnecting the battery in an under-voltage situation. They also disconnect the battery in an over-voltage situation, so protecting sensitive electronic appliances from damage resulting from faulty alternators or chargers.
There are a number of pre-programmed lower voltage thresholds that can be selected to suit your application and the battery guards automatically detect the battery voltage when connected so can be used with both 12V and 24V DC systems.
These battery guards are available in six models capable of carrying 10A, 18A, 40A, 60A, 100A and 200A continuous loads. They have very low voltage drop and standby current draw and all except the 10A & 18A versions feature an input for remote On/Off control and an output for an alarm/light/relay.
