CN100A24 SeriesTDK-Lambda Americas has expanded its line of railway DC-DC converters with the introduction of the new 24V input, 100-watt, CN100A24 Series. These quarter brick modules operate off a wide range of DC inputs from 14.4 to 36.0VDC, which is widely used in the railway industry and for 24-volt vehicles. Available with output voltages of 5V, 12V, 15V or 24VDC (adjustable ±10%), these fully-regulated and isolated power modules deliver exceptional performance.

The CN100A24 DC-DC modules are suitable for both rolling stock and trackside equipment, enabling user’s 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 higher input range versions of these modules (CNA-110, with a input range of 60-160Vdc and output ratings from 30W to 200W) as well as custom design/manufacturing services for its customers who prefer to buy a complete turn-key system that meets their exact electrical and mechanical requirements.

Designed for very harsh environments, the CN100A24 Series meet the stringent shock and vibration requirements of IEC61373 Category 1, Grade B. These baseplate-cooled power con-verters have standard pin-outs and provide full output power from -40 to +100°C at the baseplate without deratings. The 100-watt model CN100A24-12, for example, delivers 8.4 Amps at 12VDC with a conversion efficiency of 88% at full load. These quarter-brick modules measure 1.45 x 2.28 inches and are only 0.50 inch high.

As standard, the CN100A24 units are equipped with remote sense, remote on/off, overvoltage and overcurrent protection circuitry, and include TDK-Lambda’s 5-year warranty. All CN100A24 models have an input-to-output isolation of 3kVAC, are safety-approved to UL/CSA/EN60950-1 and carry the CE mark in accordance with the LV Directive.

These new 100-watt modules are available now with prices starting at $124.00 each in 100 piece quantities. More information can be obtained at the following TDK-Lambda Americas website http://www.us.tdk-lambda.com/lp/products/cn-series.htm or by calling 800-LAMBDA-4.
