PDUMH30AT Metered ATS / Auto-Transfer Switch offers 120V 30A dual-input power distribution and visual current metering in a 2U horizontal rackmount installation format. Set of two NEMA L5-30P line cords enable separate primary and secondary input connections. Includes 25 built-in outputs (24 NEMA 5-15/20R and 1 L5-30R). Digital current metering with push-button display control tracks output power consumption in 4 segments: Bank 1 (12 upper 5-15/20R outlets), Bank 2 (12 lower 5-15/20R outlets), L5-30R (single outlet) and total PDU output. Supports 2U installation in 2 or 4 post racks, with additional support for wall-mount and under-counter placement.

120V 30A Automatic Transfer Switch (ATS) / Metered PDU (Power Distribution Unit), Agency de-rated to 24A continuous

Provides a redundant power option for critical networking equipment with a single input power cord

2 digit display with segment selection button reports output power consumption in amps for four output segments (Segment 1: 12 5-15/20R outlets / Segment 2: 12 5-15/20R outlets / Segment 3: L5-30R outlet / Segment 4: total output of all outlets combined)

2U horizontal rackmount form factor; 12.5 in. / 31.8 cm depth

25 outlets (24 5-15/20R, 1 L5-30R)

Set of two 10 ft. / 3m NEMA L5-30P input line cords enable separate PRIMARY and SECONDARY input connections

ATS circuits normally maintain output sourced from the primary input cable; As primary input power fails or becomes unstable, the ATS will switch to maintain output sourced from the secondary input cable until power on the primary input is restored and stable

ATS configurations enable fault-tolerant, hot-swappable UPS protection when used with a single UPS and fully redundant UPS protection when each cord is connected to a separate UPS system (in a two-UPS environment, the primary input cable must be supported by an online UPS with zero transfer time similar to Tripp Lite SmartOnline series)

Advanced ATS configurations utilizing separate mains circuits, backup generators and even separate out of phase utility power grid feeds are fully supported

On-board ATS processor constantly evaluates power quality on both inputs to prevent transfer to the secondary source when unavailable or of lower quality than the primary source

Super-fast switchover between primary and secondary power sources occurs in 3-6 milliseconds

Front panel LEDs confirm power availability on both input lines
