Overview

Tripp Lite's Metered Automatic Transfer Switch / ATS PDU provides a redundant power option for single-corded network devices. Dual input cords support separate connection to PRIMARY and SECONDARY power sources. The ATS will normally maintain continuous output to all outlets as derived from the primary input cable. 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. Super-fast switchover between primary and secondary power sources occurs within milliseconds. ATS functionality is supported by any two compatible AC power sources, regardless of phase angle, 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. Tripp Lite SmartOnline series is highly recommended for use as the primary UPS in a two-UPS application. ATS configurations utilizing separate mains circuits, backup generators and even separate utility power grid feeds 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 input LED's display primary or secondary power availability.

Features

  • 120V 20A Automatic Transfer Switch (ATS) / Metered PDU (Agency de-rated to 16A continuous)
  • Provides a redundant A/B power option for non-redundant networking equipment with a single input power cord
  • Digital display continuously reports total output power consumption in amps
  • 1U horizontal rackmount form factor; 14.5 in. / 36.8 cm depth
  • 16 built-in NEMA 5-15/20R outlets (8 front / 8 rear)
  • Set of two 12 ft. / 3.6m NEMA L5-20P input cables with set of two 5-20P adapters support connection to separate PRIMARY and SECONDARY inputs
  • 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 2-7 milliseconds
  • Built-in card slot supports optional SNMPWEBCARD or WEBCARDLX for permanent upgrade to a switched & monitored PDU system
  • Outlets are factory programmed for sequential turn-on at 250 millisecond intervals when the PDU is first energized to prevent inrush-related equipment interaction on startup
  • Front panel LEDs confirm power availability on both input lines
  • Compliant with the Federal Trade Agreements Act(TAA) for GSA Schedule purchases

Package Includes

  • ATS / Metered PDU with attached L5-20P primary input cord
  • Detachable C19 to NEMA L5-20P secondary input cord
  • Set of two L5-20R to 5-20P plug adapters
  • 1U rackmount installation brackets
  • User manual with warranty information
TAA compliant RoHS compliant
