SynQor has announced the release of the IQ36xxxQTA family of Isolated Quarter Brick DC/DC Converters. While targeting predominantly the Railway & Transportation industry, the devices will also suit a variety of other applications due to the ultra wide 4:1 input voltage range of 18-75V.
By adding this 36V nominal input device to the InQor family of Industrial DC/DC converters, SynQor now offers a complete suite of quarter brick products for Railway applications required to operate from a nominal 24V, 36V, 72V or 110V input. Each individual voltage range is designed to meet the respective input requirement of EN50155 including associated transients.

The industry standard footprint and pinout device offers up to 120W of power in the following single output configurations - 1.8V/40A; 3.3V/30A; 5V/24A; 7V/17A; 12V/10A; 15V/8A; 24V/5A; 30V/4A and 48V/2.5A. With a wide trim range of +10%/-20%, several other voltages can easily be achieved ranging from 1.45V to 53V. Basic grade isolation from input to output of 2250Vdc offers the flexibility of choosing either a positive or negative output, as well as being able to connect the outputs in series to create higher voltages.

The devices are available in one of three mechanical configurations - open frame for convection-cooled applications; with an attached baseplate for conduction-cooled applications; and fully encapsulated for harsh environment applications. The encapsulated option brings the additional benefit of having reinforced-grade isolation from input to output.

Calculated MTBF figures of the IQ36-QTA series are in excess of 2MHrs, and all units are fully 6/6 RoHS compliant. Further control and protection features include remote sense, input under-voltage lockout, output OVP, current limit, short circuit protection, and thermal shutdown. Operating temperature range is -40 to +100degC.
