Power protection and connectivity solutions manufacturer Tripp Lite has introduced a new line of 3-phase rack-mount ATS Power Distribution Units (PDUs). These 1U rack-mount automatic transfer switches (ATS) work with compatible 0U PDUs to deliver up to 17.3 kW of redundant 208V AC power to data center servers, storage, and network equipment. The ATS units also feature a network interface for remote power monitoring.
Tripp Lite’s 3-phase rack-mount ATS PDUs, with 30-amp to 60-amp input options, can deliver 8.6 to 17.3 kW of redundant, reliable power to single- or dual-corded rack loads with high energy efficiency in a compact form factor, saving in-rack space and improving airflow.
The 3-phase ATS PDUs have dual inputs for connection to separate primary and secondary 3-phase power sources, including out-of-phase sources, separate mains circuits, backup generators, and separate utility power grid feeds. This ability to use any two compatible 208V AC power sources offers flexibility for a variety of advanced redundant power applications.
Hybrid solid-state switching boasts reliable transfer between power sources in 1 to 5 milliseconds to keep connected equipment running without interruption. An on-board ATS processor evaluates power quality on both input sources to prevent transfer to the secondary source when it’s unavailable or of lower quality than the primary source.
“We believe this ATS PDU series allows high-density data center designers an architectural choice that has never existed before,” says David Slotten, Tripp†Lite vice president of product marketing. “Dual power source inputs, solid-state switching, and remote monitoring at these 3-phase power levels will save data center operators thousands of dollars per rack over alternative in-rack power strategies.”
