Quarter-brick 100W power module meets railway standards

TDK-Lambdavisit website


TDK-Lambda UK is launching the CN100A24 quarter-brick 100W power module, effectively adding a 24V DC input series to its CN-A family of railway DC-DC power modules. The robust new product is compliant with the applicable railway standards, and its high-reliability design affords a long warranty period of five years.

Suitable for both rolling stock and fixed installations, the CN100A24 modules enable customers to design cost-effective EN 50155 compliant systems without the risks associated with custom product designs - and more quickly. These compact and efficient CN-A24 power modules meet the growing demand for energy conservation within the railway industry and complement the existing CN-A110 series (60-160V DC), thereby helping to accelerate the adoption of industry-standard power modules within the railway industry. 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 use in harsh environments, the 100W module in the CN-A24 series meets the stringent shock and vibration requirements of IEC 61373 Category 1 Class B, as well as the Japanese equivalent standard JIS E 4031. The baseplate-cooled CN100A24 module, with industry-standard quarter-brick pinout, accepts a wide input voltage (14.4-36V DC) with 40V DC surge capability for 3s, and provides exceptionally high, true usable power from -40 to +100degC without derating. With nominal output ranging from 5 to 24V, it offers up to 88 per cent power conversion efficiency, 60W/in3 power density and delivers up to 20A usable output current in a package measuring 36.8 x 12.7 x 57.9mm (1.45" x 0.5" x 2.28").

As standard, all models in the CN-A24 series are equipped with remote sense, remote on/off and input-to-output isolation of 3.0kV AC for 1min, as well as overvoltage and overcurrent protection. Delivered with TDK-Lambda's five-year warranty, the CN100A24 is safety-approved to UL/CSA/EN 60950-1 and is CE marked to the Low Voltage Directive (LVD).
