1-3 PRODUCT FEATURES
The following describes the major sub-systems within the ETERNALIGHT 1 UPS.
INPUT AND OUTPUT FILTER – The input filter reduces the input transients and
harmonics on the input line. This helps protect the electronic circuitry of the UPS. The
output filter filters and noise and line spikes from loads.
INPUT POWER FACTOR CORRECTION - The ETERNALIGHT 1 UPS system includes
state – of – the – art input power factor correction. This greatly reduces the amount of
current demanded from your building wiring system, yielding a highly efficient “Building
Friendly” UPS System.
RECTIFIER/INVERTER
The Rectifier-Inverter system provides controlled sine wave power to the output. The
output voltage and frequency are monitored by the microprocessor and controlled to
provide precision power with changing inputs and outputs to the UPS system.
MICROPROCESSOR, Display
The microprocessor monitors the input and the output to the UPS system and corrects
for any abnormal condition that may occur. This is displayed on the display for operator
information.
DIAGNOSTIC TESTS
When you start the UPS, a diagnostic test is automatically executed that checks the
electronics, batteries, and reports and problems on the display.
