HD Series Line Interactive UPS

HD Series brief
HD Series ( 1000VA-5000VA ) Line Interactive UPS uses line interactive technology and provides a sinusoidal output with power factor 0.8. It consists of inverter, automatic voltage regulator, conversion circuit, main control circuit and display alarm circuits etc. It is designed to protect your computer and other important electronic equipment from power failure, brownouts, sags and surges. When the utility power is normal, UPS has voltage regulation function by internal automatic voltage regulator, meantime charge the battery. When the utility power is unnormal, ups can change the battery energy into pure sine wave AC power, make the load work. It is the ideal solution for the protection of Computer center, Network management center, Communication system, Automatic control system, ATM, Precision instrument and equipment, household appliances etc.

Main Features

Two appearance design: Tower type and Rack-mounted type
Intelligent digital control technology, make pure sine wave output
Intuitive LED Status Indicator, Humanized LCD Display
0.8 output Power Factor lives up to the load trend and stronger load
Automatic voltage regulation (AVR), wide input voltage range, improve the output voltage regulation accuracy
Line interactive mode design: high-efficiency, high-power charging ;
Intelligent battery management, extend the battery life
High efficiency inverter, make the performance more stable and reliable
