True On-Line Double Conversion Technology with Galvanic Isolation
When main power is present, the UPS converts the input AC voltage to DC to charge the battery and to supply the inverter with energy. The inverter generates a sinewave AC voltage which is permanently available at the output of the UPS through an isolating transformer. If a problem occurs with the main power supply, the battery delivers the necessary power to the inverter, additional bypass system which is integrated into the UPS guarantees the highest possible level or reliability. In cases of overload or short circuit, the bypass system automatically connects the main power input directly through to the electrical load.
