PB20

The PB20 is designed to be used with EDAC products. The unit produces a continuous output of 13.8V DC at loads up to 4A. During mains fail the internal battery can maintain operation for periods from one hour upwards depending on load. The 13.8V output is electrically regulated, providing a constant voltage over the 0 to 4A output current range and providing standby charging of the battery.
