The PowerShield Centurion RT PSCERT1000 is a 1000VA Online Rackmount or Tower UPS that is designed to protect critical computers, communications, industrial, medical and other mission critical equipment. As a true online double conversion UPS the Centurion RT is PowerShield's highest single phase power density UPS. Boasting an output power factor of 0.9, it 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 .
