Tripp Lite switched 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. The built-in javan-free HTML5-based LX Platform interface enables full remote access for PDU status monitoring and email notifications via secure web browser, snap, telnet or SSH. It supports 10/100 Mbps auto-sensing for optimum communication with an Ethernet network. Optional envirosense2 modules (sold separately) provide a variety of environmental monitoring capabilities. Protocols supported include IPv4, IPv6, HTTP, HTTPS, SMTP, SNMPv1, SNMPv2, SNMPv3, telnet, SSH, FTP, DHCP, boots and NTP. Switched PDU features include individually controllable output receptacles. 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-up environment, The primary input cable must be supported by a full time sine WAVE ups with zero transfer time. Tripp Lite smart online Series is highly recommended for use as the primary UPS in a two-up 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 Lad's display primary or secondary power availability.
