FREMONT, Calif., March 17 /PRNewswire-FirstCall/ -- Digital Power announces the release of its new Automatic Transfer Switch (ATS), a state-of-the-art power switching and management module that monitors, selects, and transfers up to 600 W of AC power between two independent AC power sources in less than 10 mS.
This device was developed for an industry-leading broadcast TV OEM's application in which AC power must be quickly transferred between a primary and a back-up source, typically within 7 mS, to prevent service downtime and loss of revenue for broadcast TV operators. The broadcast TV industry defines a maximum time limit for restoration of power upon a power outage, and this ATS allows broadcast operators to satisfy that requirement. This device also is suitable for a wide range of applications in telecommunications, Internet infrastructure, security & surveillance, and other areas that require a fast transfer to a back-up power source.
The ATS features a universal AC input range (85 to 264 VAC, 47 – 63 Hz with capability up to 440 Hz) and fully supports electronic switch mode power supply (SMPS) load types that incorporate active power factor correction. An on-board microcontroller provides real-time DSP monitoring and analysis of incoming AC line voltage, regardless of wave shape. Most functions and features can easily be defined by users to meet requirements of unique applications. For example: users can designate either of the two AC inputs as the primary source of power; users can program input voltage threshold detection and transfer limits; users can adjust the time delays for transfers; users can set specific operations of LED visual indicators (function/intensity/blink rate). In addition, a serial I2 C bus allows programmable serialization and part numbering data to be stored. With a power transfer efficiency of 99% and a MTBF reliability of >1.5 m hours per Bellcore 332 Issue 6 (30 degrees C), this ATS can significantly enhance the value of an end user's system.
