FPRA Flexi Power Rectifier

The FPRA is a 6kW output power AC rectifier package made up of three individual 2kW AC/DC power modules operating in a parallel mode configuration. The FPRA also includes a Power Distribution Assembly (PDA), which has a fully integrated battery protection LVD, load/battery circuit breakers, battery current shunt and alarm signals to the BTS EAC interface.
