DC to DC Power Supplies (Converters)
DC-DC Converters suit railway and 24 V vehicle applications.
Press Release Summary:
Operating off 14.4–36.0 Vdc inputs, 50 Watt CN50A24 Series offers output voltages of 5, 12, or 24 Vdc. Baseplate-cooled quarter-brick modules provide full output power from -40 to +100°C at baseplate without derating. Model CN50A24-12, for example, delivers 4.2 A at 12 Vdc with conversion efficiency of 86% at full load. Measuring 1.45 x 2.28 x 0.50 in., fully regulated and isolated units are equipped with remote sense and remote on/off as well as overvoltage and over-current protection.
Original Press Release:
New 50-Watt DC-DC Converters are Ideal for Railway and 24V Vehicle Applications
Baseplate-cooled quarter-brick modules address 50W demand for railway applications
San Diego, CA – TDK Corporation announces the release of TDK-Lambda’s new CN50A24 series of 50W railway DC-DC converters. 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, or 24VDC (adjustable ±10%), these fully-regulated and isolated power modules deliver exceptional performance.Â
The CN50A24 DC-DC modules are suitable for both rolling stock and trackside equipment, enabling users to design cost-effective IEC61373 compliant systems without the risks associated with custom product designs and in a much shorter timescale. In addition, 100W 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 160Vdc and output ratings from 30W to 200W.
Designed for very harsh environments, the CN50A24 series meets the stringent shock and vibration requirements of IEC61373 Category 1, Grade B. In addition, a conformal coating option (add /CO suffix to model number) complies with the EN50155 requirements. These baseplate-cooled power converters provide full output power from -40 to +100°C at the baseplate without derating. The 50-watt model CN50A24-12, for example, delivers 4.2 Amps at 12VDC with a conversion efficiency of 86% at full load. These quarter-brick modules measure 1.45 x 2.28 inches and are only 0.50 inch high.Â
As standard, the CN50A24 units are equipped with remote sense, remote on/off, overvoltage and over-current protection circuitry and include TDK-Lambda’s 5-year warranty. All CN50A24 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.
