Tripp Lite's PDUMH20 AC power distribution unit offers a digital current monitor and provides 20 amps of 120 volt capacity in a versatile multi-mount cabinet. Detachable mounting flanges are configurable for wallmount, under-counter, or 1U/0U rackmount installation. Uses only 1U of rack space when installed in any 19-inch rack, with the potential for zero U mounting in the cable management area of most rack enclosures. Built-in digital ammeter display offers continuous visual power consumption data for the entire PDU. Attractive rackmount housing with 12 rear-facing outlets measures only 4.5 inches in depth. Unfiltered electrical pass-through without a power switch makes the PDUMH20 ideal for distributing alternate waveform UPS or generator power in rack enclosures, network closets, and more. Includes 12 rear-facing NEMA 5-15/20R outlets, 15-ft. AC power cord with L5-20P input plug. Comes with 6-inch L5-20P-to-5-20P adapter, 20 amp breaker, TVSS grounding lug, and rugged all-metal rackmount case design.
