TDK-Lambda has expanded its dc-dc converter line-up with the introduction of the new CN-A Series, featuring a wide range 60-160Vdc input, which is widely used in railway applications. Available with nominal output voltages from 5V to 24V (adjustable ±10%) and power ratings up to 100W, these wide input range, fully-regulated and isolated power supplies deliver exceptional performance in the industry standard quarter brick footprint.
The modules are suitable for both rolling stock and fixed installations, enabling customers to design cost-effective EN50155 compliant systems without the risks associated with custom product designs and in a much shorter timescale. TDK-Lambda also offers a design and manufacture service for customers preferring to buy in complete systems meeting their exact electrical and mechanical requirements.
Designed for harsh environments, the CN-A Series meets the stringent shock and vibration requirements of IEC61373 Category 1 Class B*, as well as the Japanese equivalent standard JIS E 4031. In addition, all models accept the wide-range DC input commonly found in railway applications, which allows operation from any voltage between 60 and 160V.
These baseplate-cooled power supplies, with industry standard quarter-brick pinout, provide exceptionally high, true useable power from -40 to +100°C, without derating. The CN100A110-24 model, for example, offers up to 88% power conversion efficiency, 60.5W/in3 power density and delivers up to 4.2A useable output current in a package measuring (mm) 57.9 L x 36.8 W x 12.7 H.
As standard, they are equipped with remote sense, remote on/off and input-to-output isolation of 3,000Vac, as well as over voltage and over current protection circuitry. All CN-A models are delivered with TDK-Lambda’s five-year warranty, are safety-approved to UL/CSA/EN60950-1 and carry the CE mark, according to the LV Directive.
