15.1 Basic Operation

(1)Normal Operation

In normal operation, the UPS switches automatically* between the three modes (a) to (c) depending on the state of the power.

*The UPS does not switch automatically when item ① “UPS operation mode” in §10.1 “Setup Menu Item List” is set to “Double Conversion”.

However,The UPS switch automatically according to the state of the input power and the load condition when item ① "UPS operation mode" in §10.1 "Setup Menu Item List" is set to "Economy".

(a)Active Filter mode

The UPS operates in Active Filter mode when the input power voltage is within a certain range and the output power factor is below a certain value. In Active Filter mode, the UPS receives power from the utility power source and supplies it to the load. At the same time, it compensates for high frequencies in the input power at the inverter. The batteries are kept continually charged and ready in case a problem (outage or voltage drop) occurs in the utility supply.

(b)Double Conversion mode

The UPS switches to Double Conversion mode when the input power voltage is outside a certain range. In Double Conversion mode, the UPS converts AC power from the utility power source into DC power through the rectifier, and reconverts this DC power back into AC power through the inverter and supplies it to the load. The output power is stable AC power synchronized with the input power source. The batteries are kept continually charged and ready in case a problem (outage or voltage drop) occurs in the utility supply
