LT SERIES UPS SYSTEM
Intelligent Line Interactive Sinewave - Long backup		 700 / 1000 / 1500 / 2000VA

The LT Series UPS is an advanced true sinewave line-interactive UPS system which is designed to prevent any spike, sags and blackout from reaching your sensitive equipment; ranging from computers and tele-communications systems to computerised instruments. The LT Range has a more powerful battery charger and is therefore suitable for larger battery banks, providing longer back-up times.

Under normal power conditions the UPS filters out all small fluctuations. During power failure, the unit employs its internal maintenance-free batteries to supply back-up power without any interruption. The UPS is equipped with many features, which make both your equipment and UPS more reliable.

  • Line-interactive Charger and Bi-directional Inverter - the highest performance for protection from frequent brown outs;
  • Microprocessor Based Design - digital UPS control and automatic 50/60Hz frequency select;
  • Pure Sine Waveform Output - the cleanest, most compatible AC output for computer systems;
  • Automatic Voltage Regulation (AVR) - provides stable power and true brownout and over voltage correction;
  • Intelligent Boost and Buck - additional protection for an extended AC voltage window;
  • Battery Diagnosis - self testing for limiting operation, assuring quality and longer life of battery;
  • RS232 Communication - Compatible for sophisticated monitoring software.
