US Patent 9768591 PDU with front side access to transformer compartment

A PDU enclosure defines a transformer compartment for receiving a transformer. The PDU enclosure includes a first side bulkhead and a second side bulkhead positioned adjacent to each other as viewed on a plane. The first side bulkhead and the second side bulkhead limit access to the transformer compartment from the front. The first side bulkhead defines an opening to the transformer compartment and is spaced from the second side bulkhead by a gap. The PDU enclosure further includes a removable access panel. The removable access panel includes a first portion removably coupled to the first side bulkhead and that covers the opening in the first side bulkhead, and a second portion extending at an angle relative to the first portion and removably coupled to the second side bulkhead. The second portion also covers the gap between the first side bulkhead and the second side bulkhead.
