UPStealth 2 UPS 1000W is an intelligent UPS component providing key functions including, Active Power Supervision of incoming utility AC line power; a Digital Battery Management System; Inverter and System Control functions. The UPStealth 2 UPS 1000W is designed for installation in all signalized and ITS style cabinets and can be rack mounted in 19'' EIA racks or shelf mounted. The unit has extended run time with 6 battery ports for connecting both UPStealth 2 Battery Panels and UPStealth 2 Battery Modules.  Upon detection of incoming utility AC line problems, the UPS can switch to battery back up mode in <8ms. The browser-based UPStealth 2 Software can remotely manage and monitor the status of the UPStealth 2 from your central office or locally log in at your traffic cabinets.

Intelligent Two-Stage Operation

Stage 1
This stage includes Line Conditioner, Waveform Monitoring and Switchover to battery backup functions.  The line conditioner function attenuates surges and spikes on incoming utility power thus minimizing the switchover occurrences to battery power vs. older line interactive approaches.  Oscilloscope functionality continuously measures the incoming AC waveform and monitors for voltage, waveform anomalies and frequency deviations outside of user programmed thresholds.  When any of these thresholds are exceeded, transfer time to battery backup is a rapid <8ms.  Up to 1000 events can be stored in the event log and accessed through the browser-based UPStealth software.

Stage 2
This stage includes Waveform Monitoring and Return to AC Power functions.  Through continued vigilance with the oscilloscope function, the voltage, waveform anomalies and frequency must all be within their threshold limits for a user selectable line qualification time of 3, 10 or 30 seconds prior to returning to utility AC power.  If any one of the three parameters exceeds its thresholds within the selected line qualification time window, then the time window resets to the selected line qualification time and monitoring repeats.
