Federal Signal Uninterruptible Power Systems provide a clean and constant, regulated power supply in harsh electrical environments where the available power is polluted, fluctuating or unreliable.

The Model PSU is available in a range of kVA outputs from 1.0 to 7.5 with a choice of battery life of thirty or sixty minutes. Output voltage is 120/240VAC with a choice of operating voltages from 120VAC, 208VAC and 240VAC.

Each Federal Signal Uninterruptible Power System provides steady, regulated voltage to +/– 3% and features and input power factor correction with less than 10% total harmonic distortion. Double magnetic conversion prevents damaging load-generated harmonics from backing up into the utility lines.

System status is communicated via LED indicators and an LCD display, including input voltage, output voltage, percent of battery capacity, percent of load, percent of battery charged, system on, system on battery, low battery warning and alarm.

The Federal Signal Uninterruptible Power Systems are designed to support such applications as networking, hosts/hubs, voice mail, telecommunications, industrial controls, SCADA systems, personal computers, communication closets and distributed control system.
