The cyber power PDU20SW10ATNET, a 10-outlet (rear), 1U rackmount switched automatic transfer switch (ATS) power distribution unit (PDU), provides 100-120V 20A output. It distributes unfiltered electrical pass-through to 10 NEMA 5-20R receptacles from redundant NEMA 5-20P plugs. Dual power cords can be plugged into separate power sources to provide 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.
