Merlin Power System’s PowerGuard is a single box solution for preventing engine batteries from discharging to a level where the vehicle will not start.
Once installed, it constantly monitors battery voltage. When its protection threshold voltage has been reached, the product’s internal timer is started. If the voltage does not recover during this timed period, it isolates the batteries to prevent further power drain.
PowerGuard prevents flat batteries and helps limit vehicle downtime saving money on unnecessary battery replacement. It is available for use with vehicle electrical systems up to 300 A and 600 A.
