The FlexPower FPO75-B100D8E1 is a dual voltage, offline switchmode power supply-battery charger system specifically designed for the access control segment of the lifesafety industry. Providing for eight 12/24V auxiliary power distribution outputs, the unit is configured in a painted, steel, locking enclosure with tamper switch and integral battery space. Each auxiliary output is programmable for continuous power output from either of the two power supplies. Complete fault detection and reporting, with programmable fault delays, is provided along with datalogging capability of fault occurrence, battery usage time and power supply status. System will provide six hours of standby with a typical 65W load and a battery set rated at 24V, 18Ah. Designed specifically to support the dual voltage requirement of 12 and 24VDC, this unit utilizes an FPO to generate 24VDC and a B100 Class 2 power limited power supply to generate 12VDC. The FPO/B100 combination offers significant space and cost savings, and requires only one battery set to backup both DC voltages.
