Low Frequency Three Phase (3/3) Online UPS

EH9115 Series (20-200KVA)

Its advanced battery charging system enables the UPS to supply a long backup time while the charging time is rather short, and its temperature compensation system can help to prolong the service life of the battery. Also, its circuit is simple, which reduces the number of components and makes the manchine more compact and more reliable.Its true double-conversion online technology provides pure and safe power supply to all appliances, communication equipment and important loads connected to the internet, and the DSP technology responds quickly to different power supply problems, making sure its load will work uninterruptedly.It is compatible to all kinds of loads and widely used in the fields of energy sources, transportation, office, medical equipment, engine-room, data center, toll station and so on.

Features:

  • Range from 20kva to 200kva;
  • Ture double-conversion online technology;
  • DSP 100% micro controlled;
