Tripp Lite Metered ATS / Auto Transfer Switch PDU systems enable redundant power configurations for network devices with a single input cord connection. Set of two ATS inputs support connection to separate PRIMARY and SECONDARY power sources. The ATS normally maintains continuous output to connected equipment derived from the primary input. If the primary input fails or becomes unstable, the ATS will switch over to the secondary power source until the primary input is restored and stable. Super-fast switchover between primary and secondary power sources occurs within milliseconds. ATS functionality is supported by any two compatible AC power sources to support a variety of advanced redundant power networking applications. Enables 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 a full time sine wave UPS with zero transfer time, similar to Tripp Lite SmartOnline series. ATS configurations utilizing separate mains circuits, backup generators and even out-of-phase power sources are fully supported. On-board ATS processor constantly evaluates power quality on both input sources to prevent transfer to the secondary source when unavailable or of lower quality than the primary source. Front panel current meter offers continuous ATS loading information. Input LED's display primary and secondary power availability. Key Features 208/240V Automatic Transfer Switch (ATS) / Metered PDU (Power Distribution Unit); 30A maximum capacity (agency de-rated to 24A) Provides a redundant power option for critical networking equipment with a single input power cord Front panel digital ammeter with scroll button continuously displays output load level in amps (selectable for bank 1, bank 2, L6-30R and total PDU output) 2U horizontal rackmount form factor; 12.5 in. / 31.7 cm depth 19 built-in outlets (16 C13, 2 C19, 1 L6-30R) Set of two 10 ft. / 3m NEMA L6-30P input cables support connection to separate PRIMARY and SECONDARY power sources 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 as 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 2 UPS environment, the primary input must be connected to an online double conversion UPS 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 primary and secondary power availability and indentify the currently selected load segment reported by the current meter Typical Applications Ideal for datacenters, computer rooms and network closet applications to provide single-corded network hardware with redundant power in a metered PDU format Package Includes Auto Transfer Switch PDU Rackmount installation brackets Installable plug-retention shelves & cable ties
