The PWRgate PG40 is a simple 12V DC backup power system that can supply up to 40A continuously from either a mains PSU or battery. In other words it acts similar to an uninterruptable supply as used with computers except that the mains PSU and battery are separate.
When connected up, it means that the 12V DC mains PSU will supply the station or the rig (depending on how it is connected) until there is a mains failure, and then the PG40 will automatically switch over to the 12V battery. When the main supply is restored the rig or station will be run off the 12V DC mains PSU and the PG40 will trickle charge the battery.
