Metered ATS PDU with 25 outlets

The Tripp Lite PDUMH30AT is a metered automatic transfer switch power distribution unit built for 120 V AC environments. It accepts two NEMA L5-30P inputs and delivers power through 24 NEMA 5-15/20R and one NEMA L5-30R receptacles. The 2U horizontal chassis mounts in standard racks or on walls. Local metering shows real-time load in amps.

Suits dual-corded racks needing automatic failover

This unit targets administrators who require redundant power feeds with sub-cycle switching between sources. It fits installations where 30 A service and mixed 5-15/20R plus L5-30R outlets match the connected gear. Sites limited to 15 A or 20 A circuits, or those without dual input feeds, will not use the transfer function and should consider a single-input PDU instead.

30 A dual-input rating decides fit

The PDU draws up to 30 A per input at 100–127 V AC, so each feed must be protected by a 30 A breaker and wired with a NEMA L5-30P plug. If the available circuits are rated lower, or only one feed exists, the ATS capability cannot be used and the product will not match the infrastructure.

Questions about this item

Will the dual NEMA L5-30P inputs work with my existing 30 A 120 V generator feed?

Yes, each input uses a NEMA L5-30P plug rated for 30 A at 120 V AC, matching a standard 30 A generator receptacle.

How can I confirm the automatic transfer switch is functioning after installation?

The front-panel digital meter displays real-time voltage and current; a smooth switchover between the two inputs without output interruption shows the ATS is operating correctly.

Which cords or adapters must I purchase separately to connect 24 standard servers and one locking device?

The unit provides 24 NEMA 5-15/20R outlets and one NEMA L5-30R outlet; you only need matching C13-to-5-15 cords for the servers and a C13-to-L5-30 cord for the locking device.
