SINGLE PHASE ONLINE DOUBLE CONVERSION SINEWAVE UPS 1000VA – 3000VA, NS LCD SERIES
Description
The backup series is composed by: Rectifier, Inverter, Static Switch, manual by-pass and Battery.
The Rectifier-Inverter line normally feeds the users, and the Battery is kept charged by the Rectifier. The wide input voltage tolerance of 110-300 V allows under-voltage or over-voltage correction without unnecessary battery drain and helps extend battery life.
If a black out occurs, the Battery supplies power energy to users always through the Inverter. When the blackout is over, the Rectifier provides for Battery charge.
If a short circuit or an overload occurs to the users, the Static By-pass switches the load over the emergency line, provides visible and audible alarms, and cuts the output supply automatically until the short circuit situation is resolved manually.
