Model Number: EA890 160KVA ~ 600KVA (3:3)
Brand Name: EAST
Key Specifications/Special Features:
EA890 series UPS 160~500KVA use double conversation technology with a very advanced design criteria improves the performance of components, minimizes the quantity of raw material used on the magnetic and reduces the number of semiconductors thus reducing servicing time and ownership costs. This UPS has high efficiency (> 93%) and input power factor (> 0.99) built-in output isolation transformer. The inverter transformer prevents the direct feed-through of the battery potential into the critical load and allows a very high rejection ratio of the power supply disturbances (spikes, surges etc).FeaturesOnline double-conversion with DSP controlIGBT rectifier and high input power factor ( > 0.99)High efficiency 93%Output power factor 0.9Low input distortion: THD < 5%
