SAN DIEGO, 23 July 2013. TDK Lambda Americas in San Diego is introducing the CN50A24 series of 50-Watt rugged DC-DC converters for railway and 24-volt vehicles. The quarter-brick power electronics modules operate off DC inputs from 14.4 to 36 volts DC.
Available with output voltages of 5, 12, or 24 volts DC, adjustable plus-or-minus 10 percent, these regulated and isolated power modules are suitable for rolling stock and trackside equipment.
In addition, 100-Watt versions of these converters are included in the CN100A24 series. Moreover, TDK-Lambda also offers higher input range versions of these modules, the CNA-110 series, with an input range of 60 to 160 volts DC and output ratings from 30 to 200 Watts.
Designed for harsh environments, the CN50A24 series meets the stringent shock and vibration requirements of IEC61373 Category 1, Grade B. In addition, a conformal coating option complies with the EN50155 requirements.
These baseplate-cooled power converters provide full output power from -40 to 100 degrees Celsius at the baseplate without derating. The 50-Watt model CN50A24-12, for example, delivers 4.2 amps at 12 volts DC with a conversion efficiency of 86 percent at full load. The modules measure 1.45 by 2.28 inches and are half an inch high.
As standard, the CN50A24 units are equipped with remote sense, remote on/off, overvoltage, and overcurrent protection circuitry and include TDK-Lambda's five-year warranty. All CN50A24 models have an input-to-output isolation of 3 kilovolts AC, are safety-approved to UL/CSA/EN60950-1 and carry the CE mark in accordance with the LV Directive.
