UPS Introduction
The UPStealth 2 UPS 1000W is a 1000W UPS that utilizes an Intelligent Two Stage Operation with an oscilloscope
function and is developed to operate with nickel-zinc batteries. It is designed for installation in all signalized and ITS
cabinets and can be rack mounted in 2U - 19'' EIA racks or shelf mounted.
UPStealth 2 UPS 1000W functions using an 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. Oscilloscope functionality
continuously measures the incoming AC waveform and monitors for voltage, frequency and waveform anomalies
outside of user programmed thresholds. When any of these thresholds are exceeded, transfer time to battery backup
is <33ms.
Stage 2:
This stage includes Waveform Monitoring and Return to AC Power functions. Continued vigilance by the
oscilloscope function in Stage 1 monitors the incoming utility AC line for recovery within the user-defined thresholds.
The voltage, waveform anomalies and frequency must all be within their threshold limits prior to returning to utility
AC power. If any one of the three parameters exceed their thresholds within the line qualify time of 3, 10 or 30 second
windows, then the time window restarts once all parameters are again within their proper ranges.
