Ensure continued operation of critical devices with the CyberPower PDU24004 Metered ATS PDU. Ideal for data centers and network closets, this unit provides power redundancy to single-corded connected equipment. If power for the primary source exceeds the lower or upper thresholds, or if power fails, the PDU will switch to the secondary power source to ensure continuous operation. The PDU will switch back to the primary power source when incoming power becomes stable. The PDU24004 supports inputs between 200-240V and includes (12) IEC C13 outlets. Dual IEC C14 power cords are plugged into separate power sources (A and B), and information about each power source is provided via LED indicator lights on the front of the unit. Other features include an LCD with selectable background color, ugradeable firmware, and network-grade plugs and outlets. The CyberPower PDU24004 is protected by a three-year limited warranty.
