Product Description


1. High Performance Index


  • LI-N Inverter has both Selection of Inverter Prioritized or Utility Power Prioritized Mode to reduce energy loss.
  • DC Input adapts multiple wave filters and electromagnetic isolator to reduce the interference to the input due to the reflected related psophometrically noise, which means this feature reduces all kinds of interferences to devices connected to the DC screen to reach the telecommunication standard.
  • LI-N Series has DC Input Reverse Connection Protection Function to prevent any damage or loss due to DC misconnection of anode and cathode. It also has DC (Or Battery) misconnection alarm and protection accessories to protect the whole system.
  • LI-N Series adopts the fifth generation IGBT technology to achieve high inverter efficiency up to 90%. It also has the online single phase input and output double conversion structure to adapt 220/230/240Vac, 50/60Hz grid standard.
  • Intelligent fan control and fan failure-alarm function: LI-N/INV inverter uses intelligent air blast cooling technology to control fan speed. It will changes fan speed based on capacity of Loads, which effectively improves life-time of fan and system overall efficiency. It also reduces energy lost. Fan failure-alarm function prevents damages to machines due to fan failures, and provides promptly warning and replacements in order to avoid deferred maintenance.
  • High Overload Capacity and ability. 1-3 KVA: 60s at120% Load, 30ms turn to bypass and alarm.
  • LI-N/INV inverter allows users to cut DC Inverter output during operating states and turn to Mains Power Supply. It can reach 0ms conversion without power supply disruptions. This helps maintainers to maintain or change batteries conveniently.
  • LI-N/INV has special design to alarm and cut off output when DC Inverter (or batteries) in over-voltage or under-voltage states.
  • When DC Inverter (or batteries) restores to normal, power output will be restore automatically. This function is suitable to unattended communication base stations. (This feature is available in Utility Power Prioritized Mode)
  • LI-N/INV has AC starts function, which can be used to start the system on DC Power failure.
  • LI-N/INV has Input Isolation design prevents inverter interferences to get into the input devices. ;
  • LI Series adapts intuitive LCD+LED display to comprehensively show UPS operation status, parameters, and messages.
  • LI Series has internal temperature monitoring and protection functions.


2. Safe and Reliable


  • LI-N Series Inverter adapts full-digital DSP technology to reduce the harmonic distortion.
  • LI-N Inverter has both selection of Inverter Prioritized or Utility Power Prioritized Mode to reduce energy loss.
  • LI-N Inverter adapts sensitive peak current protection circuit design to protect the system from damages due to short-circuit, cold load impacts.
  • 90% of system components are from international famous brands. All devices has been aged and fully tested for at least 24 hours before leaving the factory.
