The FLEXPOWER FPO250-B100E2 is a dual voltage offline power supplybattery charger specifically designed for the lifesafety industry. The FPO250 power supply generates 24V, charges a battey set and provides primary power to the B100 module. The B100 steps 24V down to 12V for system use, allowing one 24V DC standby battery set to economically backup both voltages. Complete fault detection and reporting, with programmable fault delays, is provided along with datalogging capability of fault occurrence, battery usage time and current power supply status. FLEXPOWER enclosures are painted steel with removable backplate and include lock, two (2) keys and tamper switch.
