Prime Pro Series 6KVA to 40KVA Online LF UPS

The Prime Pro series features single-phase online double-conversion UPS systems with a power range of 6kVA to 40kVA. It is available in stand-alone and parallel configurations, in both 3/1 and 3/3 models. The system supplies high quality, stabilized sine-waves signals. A static switch provides the optimal solution for output inrush current and overload problems. All parameters (input/output voltage, currents, frequencies, DC voltage, and temperatures) are measured and shown in an LCD display. All information may be sent to the host computer through an RS232 interface, with SNMP management.


  • High input power factor; green and energy-saving power: -The I/P power factor is above 0.98;Input current THDI 5% ,which greatly reduces the humornic pollution of the AC network, and at the meantime, the efficiency of the usage of the utility is improved , and the installation cost and the noise is reduced. The speed of the fan can be auto-adjustable as well; all these make the UPS green energy-saving power.
  • Wide input voltage and frequency range: - With the wide input voltage and frequency range, it reduces the frequency of battery discharge so that the battery life can be prolonged and in the meantime, it can works with oil generator.
  • Reliable parallel technology :- It adopts the most advanced parallel control technology and digital equal flow control technology to make the UPS highly compatible and have the choice of N+1 parallel and redundancy and share battery sets.
  • Abundant interface setting functions:- The user can set the O/P voltage and frequency through the front panel buttons and the UPS can be set to connect equipent with different voltage and frequency.
  • Flexible network monitoring and management :- The UPS is available with RS232, USB, EPO,RS485(optional), SNMP(optional), dry contact(optional) ect.; it can support TCP/IP protocol with remote control; The network monitoring and management enables the UPS to have the function of self-diagnosis, timingly sending the demanding instruction, email, automatically saving the files and turning off the UPS ect..
  • Cold start and AC start function:- When AC fails, UPS can be started in battery directly;In AC mode,UPS can be started by AC directly without battery; when the battery discharges and there is low voltage protection, after AC returns, the UPS can start up automatically.
  • Easy maintenance design :- English display option,manual bypass design,failure information enquiry orientation…all is convenient for user and in the meantime,improving the usability and maintainability of the system.
