Coating Option Developed for CN-A Series of DC-DC Power Modules Ideal for Rail Transport Equipment

August 21, 2013

The CN-A series of DC-DC power modules ideal for rail transport equipment has been marketed under the TDK-Lambda brand since 2011. TDK-Lambda has now developed a version with resin coating of the PCB and mounted components. Orders for this standard option product called "CN-A / CO" will be accepted from July 2013.

Equipment for rail transport use must meet high requirements with regard to reliability and safety, as defined in Japan by JIS and internationally by other standards such as IEC, ISO, DIN, EN, etc. Rail transport equipment can be largely divided into two categories, namely track side equipment and rolling stock equipment, consisting of many kinds of component elements. The use of purpose-built power supplies therefore was common until recently, but concern for the environment and the call for energy-saving designs have resulted in a need for standard type power supply products offering compact dimensions and high efficiency, as well as the flexibility for use in various configurations.

Also, while unit type or rack mount type DC-DC power supplies were common for rail transport equipment, space restrictions in recent years have led to increasing demand for low-profile products with flexible layout options such as DC-DC power modules.

By adding a coating option to the CN-A series, the need for customers to provide internal measures to meet railway standard requirements will be reduced. TDK-Lambda plans to further expand its product lineup in this strategic sector by responding to customer requests and offering products with high added value.
