Large Power UPS Three Phase 160kVA-500kVA
大功率UPS三相160kVA-500kVA
EA990系列UPS采用双重对话技术，具有非常先进的设计标准，提高了组件的性能，最大限度地减少了磁性材料上使用的原材料数量，减少了半导体数量，从而减少了维修时间和所有权成本。该UPS具有高效率（> 93％）和输入功率因数（> 0.99）内置输出隔离变压器。逆变器变压器防止电池电势直接馈送到关键负载中，并且允许电源干扰（尖峰，浪涌等）的非常高的抑制比。

EA990 series UPS 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).
