OPTI-UPS Thunder Shield TS1700B 1500 VA 900W Line Interactive w/ AVR 5 Outlets Black UPS

Automatic Voltage Regulation (AVR)
Featuring boost and buck AVR, this model provides clean, consistent AC power by automatically regulating low voltages and over voltages, without draining battery power. AVR increases the output voltage by 15% while the input voltage decreases by 9% to 25%, or decreases the output voltage by 13% while the input voltage increases by 9% to 25%.

Short Circuit and Overload Protection
During overloading the UPS shuts down at 110% load after 60 seconds or 130% load after 3 seconds, and an audible alarm sounds to notify you. In the event of short circuit the UPS output cuts off immediately or triggers input fuse protection.

Tel/Modem/LAN surge protection
With a pair of RJ11/RJ45 combo ports, this UPS prevents power surges that travel through telephone and Ethernet lines from causing damage to electronics.

User-Friendly UPS Management Software
OPTI-SAFE Sentinel provides you with important operating information. From your computer screen, you can know input/output voltage and current, frequency, battery voltage, etc., and analyze power problems.

LED Indicators and Audible Alarms
The front panel indicator lights give easy ready of UPS power status including AC Mode / Battery Mode / Battery Fault / Overload. And audible alarms notify you when the unit is in Battery Mode / Battery Low / Overload.

More Features
The Fully digitized microprocessor control ensures high reliability and precision. 50/60 Hz frequency auto sensing and selection enables compatibility in various situations. Cold start function (DC power on) enables UPS to be started up without AC power supplied. Energy saving function (UPS green mode) helps reduce utility bills and extend the battery life.
