This online series is an uninterrupted power supply (UPS) incorporating dual conversion technology. It provides perfect protection specifically for computer equipment, computerized instrument communication systems. Its true dual-conversion online design eliminates all disruptions to the AC power supply.

A rectifier converts the alternating current from the power of the utility to direct current. This DC current charges the batteries and feeds the inverter. On the basis of this DC voltage, the inverter generates a pure sine-wave AC voltage, which constantly feeds the loads. Computers and peripherals are therefore fully powered by the inverter. In the event of a power outage, the maintenance-free batteries supply the inverter.

All IPOWER of the ZONDA series are designed to ADAP an isolating transformer for a better and higher level of protection, both "IN" and "OUT".
