Optim Engineering PWRguard
DC protection system
Optim Engineering's PWRguard is an automatic safety switch inserted between a power source and the load. It switches off whenever the voltage is over 15V or under 11.5V, thus protecting the equipment being powered as well as the battery or power supply. If your power supply loses regulation and goes high, the PWRguard turns off, thereby protecting the equipment and the power supply. If the voltage drops down below 15V again, the PWRguard automatically turns back on. It will operate at up to 40 amps, and uses solid state FET switching. It protects a battery from over discharge by sensing the average voltage under load latching off for low battery, and then automatically switching back on if the battery is re-charged.
