ATS Is Solution To High-Integrity No-Break Power
Gresham Power Electronics has released the automatic transfer switch (ATS), a power switching and management module. The ATS monitors, selects and transfers up to 600W of AC power between two independent AC power sources in less than 10ms. The device was developed for a broadcast television OEM for an application in which AC power must be quickly transferred between a primary and a back-up source, typically within 7ms, to prevent service downtime and loss of revenue for broadcast TV operators.
In addition, the ATS is said to be suitable for other applications in telecommunications, internet infrastructure, security and surveillance, and similar areas that require a fast transfer to a back-up power source. The Gresham Power ATS features a universal AC input range of 85-264VAC at 47-63Hz (with capability up to 440Hz) 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 the requirements of unique applications. For example, users can designate either of the two AC inputs as the primary source of power, program input voltage threshold detection and transfer limits, adjust the time delay for transfers and set specific operations of LED visual indicators (function/intensity/blink rate). In addition, a serial IC bus allows programmable serialisation and part numbering data to be stored. With a power transfer efficiency of 99 per cent, the ATS is said to enhance the value of an end-user's system.
The Gresham Power ATS features a building block design that allows simple modification and adjustment to support any product that requires alternate switchable AC source to maintain services. It measures 38 x 108 x 216mm and includes a printed circuit board with an edge-card connector for pluggable applications. The faceplate houses to 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 6A or approximately 600VA 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 Gresham Power ATS can be configured quickly to meet customer-specific requirements for a best fit into unique applications. It supports customisations ranging from mechanical variations to faceplate silk-screening. DC input options are available. All models are CE marked, certified to EN60950 and UL60950, and support EN55022 class B emissions.
