As a true online double conversion UPS the Centurion RT is our highest single phase power density UPS. Boasting an output power factor of 0.9, this will fully protect mission critical devices as it can support larger loads than UPS products of an equal VA rating. The Centurion RT has an energy saving Advanced ECO mode, which allows the unit to operate at very high efficiency, up to 98%. When the utility mains input voltage is within the ECO range the UPS saves energy by passing the mains supply directly through to the load, while the inverter continues to operate in a passive mode .
