The CN-A DC-DC 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.
