It prevents impulse, surge, sag and power outage situations. It provides the UPS output load with a reliable source. It has the following functions: 1.1 Boost: If the utility voltage drops to line boost activated point*, the AVR will be activated and increase the input voltage by 1.18 times of incoming utility voltage. *Boost activated point 110 VAC 120 VAC 220 VAC 230 VAC 240 VAC 99 VAC 108 VAC 198 VAC 207 VAC 216 VAC 1.2 Buck: If the utility voltage reaches to line buck activated point, the AVR will be activated and decrease the input voltage by 0.85 times of incoming utility voltage. *Buck activated point 110 VAC 120 VAC 220 VAC 230 VAC 240 VAC 121 VAC 132VAC 242 VAC 253 VAC 264VAC 1.3 50/60Hz Automatic Frequency Selection: The output frequency will automatically match the input frequency (50 or 60Hz). 1.4 Communication Port (USB): It provides remote shutdown capability via communication port for connected computers. 1.5 Data line/telephone line protection: The unit provides RJ11 port to provide transient voltage surge suppression (TVSS) for data line or telephone line. 1.6 Cold start (DC start): The UPS is equipped with DC start function to turn on the UPS without input source.
