Alpha extends its family of FlexNet powering solutions to include the FN50-48-EF power module. The FN50-48- EF supports fiber-to-the-home applications including MDU, MTU and SBU ONT products. TheFN50-48-EF can be installed in indoor or outdoor applications, and provides 50Watts of 48Vdc, microprocessor controlled power. The input is powered from 120 or 240Vac. A 48Vdc string of standard 7.2Ah or 12Ah maintenance-free sealed lead-acid batteries provide standby power, if desired. The onboard microprocessor monitors and controls critical functions including temperature compensated battery charge management, periodic battery capacity testing, and local and remote status reporting providing higher service availability. This power module is suited for both North America and International Markets.
