The CN series is building Block power module, that allows system design Engineers to integrate this module onto their own pcb. This provides complete flexibility in system profile design and in addition reducing cost dramatically compare to a stand-alone DC/DC converter.

They are suitable for both rail rolling stock and fixed installations, enabling customers to design cost-effective EN50155 compliant systems.
Designed for harsh environments, the CN-A Series meets the stringent shock and vibration requirements of IEC61373 Category 1 Class B. 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 base-plate-cooled power supplies, with industry standard quarter-brick or half-brick pinout, provide exceptionally high, true useable power from -40 to +100øC, without derating.
