Tripp Lite's 120V 20A metered PDU system with Automatic Transfer Switching (ATS) 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.

User manual with warranty information
Tripp Lite Metered ATS / Auto Transfer Switch provides a redundant power option for single-corded network devices. Dual input cords support separate connection to PRIMARY and SECONDARY power sources. If the primary power source becomes unstable or fails altogether, the ATS will switch over to the secondary power source until the primary input is restored and stable. 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. 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 input LED's display primary or secondary power availability.
