Description
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. 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.
