San Diego, CA - Global power supply manufacturer TDK-Lambda has expanded its DC-DC converter line-up with the introduction of the new CN-A Series that have a wide range 60V to 160VDC input, which is widely used in railway applications. Available with output voltages from 5V to 24VDC (adjustable ±10%) with output power ratings of 30W, 50W and 100W, these fully-regulated and isolated power modules deliver exceptional performance in the industry standard quarter-brick footprint.

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 custom design and manufacture service for customers preferring to buy a complete system that meets their exact electrical and mechanical requirements.

Designed for very 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 60V and 160VDC.

These baseplate-cooled power converters have standard pin-outs and provide full output power from -40 to +100°C, without deratings. The 100-watt model CN100A110-24, for example, delivers 4.2 Amps at 24VDC with a conversion efficiency of up to 88%. These quarter-brick modules measure 36.8 x 57.9 mm and are only 12.7mm high. This translates to a power density of up to 60.5W/in³.

As standard, the CN-A units are equipped with remote sense, remote on/off, over voltage and over current protection circuitry, and include TDK-Lambda’s five-year warranty. All CN-A models have an input-to-output isolation of 3000VAC, are safety-approved to UL/CSA/EN60950-1 and carry the CE mark in accordance with the LV Directive.

The new CN-A family of DC-DC converters is available now and priced at $147.00 each in 100 piece quantities. More information can be obtained at the following TDK-Lambda website http://www.us.tdk-lambda.com/lp or by calling 800-LAMBDA-4.
