This rugged, industrial quality DC output UPS system with external battery and PFC input. The built-in battery charger provides 150W total
power for the output and for float charging the battery. The unit has a low battery disconnect circuit to prevent damage to the battery by low
discharge during prolonged AC failure. A Low Battery Alarm (F/C) provides warning before the disconnect circuit disengages the output. A
built-in charger fail alarm (F/C) indicates either failure of the charger circuit or loss of AC input power. The battery input is protected against
accidental reverse battery connection by a crossbar diode and internal safety fuse. The battery must be fused externally, directly at the
battery. Low component count, large design headroom, and the use of components with established reliability result in a high MTBF. The unit
is manufactured at our plant under strict quality control.
