High Frequency Online UPS

High Frequency Online UPS

EH5110 Series (1-10KVA)

EH5110 is a new generation of high-frequency online UPS. It adopts advanced DSP digital control technology to effectively improve product performance and system reliability, and achieved higher power density. With the characteristics of small size, light weight and high work efficiency. Effectively solve power problems such as power outage, grid high voltage, grid low voltage, voltage instantaneous drop, amplitude reduction, high voltage pulse, surge voltage, harmonic distortion, clutter interference, frequency fluctuation, etc., and provide the best power for the load.With a standard 19-inch rack construction for easy to install.


  • Double conversion online design, output zero transfer time;
  • Adopt DSP digital control, excellent performance indicators, make the control system more steady and reliable;
  • Adopt Active Power Factor Correction (PFC) technology, the input power factor is close to 1, which greatly reduced the pollution to the grid;
  • Ultra-wide input voltage range;
  • Input frequency range is 40~70Hz, ensure stable operation when connected to various fuel generators;
  • With LCD+LED real-time display, users can intuitively understand the UPS operating status;
  • With self-diagnosis function, it can detect hidden faults of UPS in time;
  • N+1 parallel redundant design, can realize 3 parallel connections, greatly improved system reliability;
  • With AC input over, under voltage protection, output overload protection, short circuit protection, temperature protection, battery under voltage warning protection and battery overcharge protection;
  • The whole machine efficiency is up to 90%. Reduce the power loss of the UPS and save the user’s cost;
  • In the absence of city power, the battery can be cold-started directly;
  • Input neutral line detection function to avoid reverse connection of UPS mains input neutral line and live line;
  • When the utility power is interrupted, the UPS will discharge in battery mode; when the utility power recover, UPS will turn on and charge the battery automatically, to achieve unattended operation;
  • Standard RS232 communication interface enables UPS and computer to realize multi-function and multi-purpose monitoring and management operations through computer window, and can install SNMP card (optional) to realize UPS remote monitoring function.


It is suitable for power protection devices such as commercial servers, PC servers and peripherals,communication and network equipment, home office computers and other sophisticated electronic equipment.
