Raritan unveils Fast and Intelligent Rack Power Transfer Switch at Cisco Live

Raritan, Inc. today introduced the Intelligent Rack Transfer Switch (PX3TS) to help keep data center equipment operating through power failures. When the new switch senses power loss, it provides fast and seamless power load transfers from one power source to another without interrupting operations. The PX3TS switch — which was announced today at Cisco Live, Cisco’s annual IT and communications conference — is targeted at cloud computing infrastructures and data center racks filled with one-power-supply devices.

Raritan’s PX3TS switch uses an innovative hybrid design to provide fast power loss detection and load transfers that exceed that of other offerings in the market, including standard automatic transfer switches (ATS), and at a lower price point and greater energy efficiency than static transfer switches. By sampling the current 4,800 times per second with built-in sensors, the Raritan switch transfers the load within four to eight milliseconds. To deliver fast performance and reliability, Raritan’s patent-pending hybrid design uses the best of both electromechanical relay and silicon-controlled rectifier (SCR) technologies.

“Every millisecond counts when there is a power failure,” says Greg More, Senior Product Marketing Manager at Raritan. “Our new hybrid rack transfer switch is one of the fastest in the industry — twice as fast as standard automatic transfer switches, which take from 10 to 16 milliseconds to transfer loads.”

The new Raritan Transfer Switch also provides remote monitoring and PDU unit-level metering to support capacity planning decisions and to utilize power resources efficiently. Real-time power information gathered by the switch can be easily shared with Raritan’s DCIM software solution for monitoring and managing the health of the rack and the data center.

Available worldwide, the Raritan Transfer Switch PX3TS comes with a number of options and a range of voltage and plug types. The PX3TS switch comes with an intelligent network-ready controller with display, and with two USB-A and one USB-B ports to support Wi-Fi networking, webcams and cascading to share IP drops. The switch’s sensor ports support optional Raritan plug-and-play sensors for monitoring environmental conditions in the racks.
