Operation Modes

In ECO mode the UPS is configured to use static bypass mode as the preferred operation mode under predefined circumstances. The inverter is in standby in ECO mode and in case of interruption to the mains, the UPS transfers to battery mode and the load is supplied from the inverter. NOTE: This mode is disabled by default, please contact ...

The power of the static switch

Accordingly, practical UPS installations include a static switch which can select between the UPS inverter output and a raw mains bypass to feed the critical load. In online UPS systems, the switch remains ''on UPS'' unless a UPS fault develops, in which case it changes over automatically and seamlessly to the raw mains supply.
