High Frequency Online UPS

EH5000 Series (10-20KVA)

This Online Series is an uninterruptible power supply incorporating conversion technology. It provides perfect protection specifically for computer equipment, communication systems to computerized instruments.The double-conversion principle eliminates all mains power disturbances. A rectifier converts the alternating current from the utility power to direct current. This direct current charges the batteries and powers the inverter. On the basis of this DC voltage. the inverter generates a sinusoidal AC voltage which is constantly powering the loads.Computers and Peripherals are thus powered entirely by the UPS. In the event of power failure, the maintenance-free batteries power the inverter.

  • • Double conversion online design, output zero transfer time;
  • • Adopt DSP digital control, excellent performance indicators, make the control system more stable and reliable;
  • • Using active power factor correction (PFC), the input power is close to 1, large reduced pollution to the mains grid;
  • • Ultra-wide input voltage range, input voltage up to 210V without switch to battery power;
  • • Automatically recognize and adapt to 50/60Hz power system, can access various fuel generators can work stably;
  • • With LCD+LED real-time display, users can intuitively understand the UPS operating status;
  • • With self-diagnosis function, it can discover hidden faults of UPS in time;
  • • N+1 parallel redundant design, which can realize 3 parallel connections, greatly improving system reliability;
  • • With AC input over-voltage, under-voltage protection, output overload protection, short circuit protection, temperature protection, battery under-voltage warning protection and battery overcharge protection;
  • • The machine efficiency is up to 90%, reducing the power loss of the UPS and saving user’s cost;
  • • Standard RS232 communication interface allows the UPS to communicate with the computer through the computer window enables versatile, versatile monitoring and management operations and installs an SNMP card (Optional) Implement UPS remote monitoring;
  • • If there is no utility, you can use the battery to start cold;
  • • With input phase sequence protection, phase sequence can not be turned on;
  • • When the utility is interrupted, the UPS is discharged to the battery in battery mode; when the city power is restored,the UPS can be powered on automatically and the battery is charged for unattended operation.


Applied to small and medium-sized enterprises, large enterprise branches, banking outlets ,miniaturized data center storage, network equipment, VOIP, communications equipment, automation equipment, office equipment terminal precision equipment, etc.
