New 1U High Automatic Transfer Switch (ATS) Allows 600 VA Uninterrupted Power Transfer Between Two AC Power Sources for Broadcast TV, and Digital Communications Applications

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.

The ATS features a building block design that allows easy modification and adjustment to support any product that requires alternate switchable AC source to maintain services. It measures just 1.5 x 4.25 x 8.50 inches and includes a printed circuit board with an edge-card connector for pluggable applications. The faceplate houses two panel-mounted AC power inlets (IEC-320 dual fused), one AC power outlet, and LED indicators for input power status. The AC model configuration allows up to a 6 A or approximately 600 VA power transfer capability into resistive, inductive or electronic loads. A metal faceplate with integrated locking hardware and an EMI gasket completes this pluggable device that can be put into a 1U, 2U, or 3U chassis.  

The ATS can be configured quickly to meet customer-specific requirements for a best fit into unique applications. It supports customizations ranging from mechanical variations to faceplate silk-screening. For complete information about available DC input options, consult Digital Power.

All models are CE marked, certified to EN60950 and UL60950, and supports EN55022 class B emissions.
