  • MacMall Part #: 7185907 
  • Manufacturer Part #: PDUMH20AT 
  • UPC: 037332126665 
  • Platform: Universal 

Tripp Lite's 120V 20A metered PDU system with Automatic Transfer Switching is a 16 outlet PDU with a digital display to indicate total PDU power consumption in amps. Outlets are sequentially turned-on at 250 millisecond intervals when the PDU is first energized from an unpowered state to prevent inrush-related equipment interaction on startup. Supports 1U rackmount installation in a 2 or 4 post rack. Included are 16 NEMA 5-15/20R outlets, and two 12 ft. L5-20P input power cords. Each cord is compatible with both NEMA 5-20R and L5-20R receptacles.

Optional integrated ATS is available for use when two separately derived input power sources are available. The attached power cord serves as the primary AC input cable, while the included detachable power cord serves as the optional-use secondary AC input connection. The PDU system passes the primary input power through to connected equipment whenever line voltage and frequency levels are normal. If the primary input source goes outside of these tolerances or fails altogether, the ATS will automatically switch all PDU output to the secondary line sourced input power when available, to maintain continuous operation of connected loads without reboots or service interruptions. Once the primary power source is restored, the PDU will automatically switch back to primary sourced input power. The dual input cabling can be configured for UPS maintenance bypass of standard UPS systems or to create a redundant dual-UPS power source for a critical, single-corded network device.


– 120V 20A metered PDU system with Automatic Transfer Switch (ATS).
– Dual input cords, one attached (primary) and one optional-use detachable cord (secondary).
– Included cordsets support 5-20P and L5-20P plug-in connections via secure adapters.
– Front panel digital ammeter displays power consumption in amps.
– 16 built-in NEMA 5-15/20R output receptacles.
– Optional ATS function enables setup for hot-swappable UPS maintenance bypass, dual UPS protection or dual AC input redundancy for critical single-corded network hardware.
– Small 1U rackmount format installs in only one rack space with a maximum installed depth of 14.5 inches.

Typical Applications:

– Ideal for configurations requiring a simple PDU that displays power consumption in amps
– Optional-use ATS function makes this system ideal for adding redundancy to single corded devices
– ATS function adds hot-swap and maintenance bypass function to standard UPS configurations
