The Gen 5 PDU offers one of the broadest selections of any PDU manufacturer. Across the top are the horizontal PDUs, which are available in 3 different form factors. The next 5 PDUs down are known as the 0U Full Form Factor. After that is the 0U Mid followed by the 0U Half. Not pictured are the 0U Full 2 sided or the 0U Half 2 Sided. These two form factors are an industry first that are designed to be button mounted on their sides; placing the outlets on 1 face and the circuit breakers on the opposite face. Having a “2 sided” PDU allows for very high outlet density and being side-mounted results in minimal egress into the EIA space.
