TDK Corporation (TSE:6762) announces the expansion of the TDK-Lambda brand CN-B110 series with 50W, 100W, and 150W rated quarter-brick DC-DC converters. Capable of operating from a wide input voltage of 43 to 160Vdc, the converters are compatible with 72Vdc or 110Vdc nominal railway systems for applications such as rail rolling stock and trackside equipment.<\/span><\/p>\n

These additional converters are available with 5V, 12V, 15V, 24V, and 48V outputs and expand the CN-B110 series from 50W to 300W. Using the trim function, they can be adjusted using a resistor or an external voltage to compensate for voltage drops or to accommodate non-standard system voltages.<\/span><\/p>\n

To meet demanding high voltage requirements for transients and 5000m altitude, the CN-B110 series has sufficient spacing between the primary input and baseplate for a 2500Vac isolation voltage. The input-to-output isolation is 3000Vac and 500Vac between the output and baseplate. With efficiencies of up to 92%, power losses are minimised, allowing the products to operate at baseplate temperatures of -40<\/span>o<\/span>C and up to +100<\/span>o<\/span>C, with very minimal to no derating at high temperatures. Cooling is achieved using the optional heatsinks or a cold plate via the module\u2019s aluminium baseplate.<\/span><\/p>\n

The 50W to 150W CN-B110 models have remote on\/off as standard, with an optional 7 to 11V 10mA auxiliary output (replacing the negative remote sense function). Other options include board coating, unthreaded mounting holes, a short 3mm pin length, and no encapsulation (50 and 100W models only). The quarter-brick converter’s overall dimensions are 12.7mm high, 37.2mm wide, and 58.3mm in length.<\/span><\/p>\n

All models carry the CE and UKCA marks for the Low Voltage and RoHS Directives and are certified to the IEC\/UL\/CSA\/EN 62368-1 safety standards. In addition, the series meets the rolling stock IEC 61373 Category 1, Class B shock\/vibration standards, and is designed to meet EN 45545-2 (Fire protection on railway vehicles) and EN 50155(1) (Electronic equipment in railroad vehicles) in certified systems.<\/span><\/p>\n
