XP Power extends line up of EN50121-3-2 certified DC-DC converters for railway and rolling stock applications
XP Power today announced the RDC20 and RDC40 series of 20 Watt and 40 Watt metal encapsulated wide range DC-DC converters designed for railway and industrial applications. These highly efficient PCB mounted converters, typically 90%, comply with railway and rolling stock EMC standard EN50121-3-2 and can accommodate a wide range of input voltages. Both series are available with either a nominal input of 72 VDC (range 36 140 VDC) or 110 VDC (range 55 176 VDC).
Combined with their small size, the RDC20 measuring only 25.4 x 50.8 x 10.16 mm (1.0 x 2.0 x 0.4 inches), and a high efficiency, the RDC20 and RDC40 offer a high power density with minimal wasted heat. Both series can be used over the extended temperature range of 40 degrees C to + 85 degrees C and can operate to full power using convection cooling up to + 50 degrees C or up to + 60 degrees with an optional heat sink. Maximum case temperature is + 105 degrees C.
Both series are available with either single or dual outputs. Single output models are available with + 3.3, + 5, + 12 or + 15 VDC. Duals comprise +/- 12 or +/- 15 VDC outputs. The RDC20 also has a +/- 5 VDC dual output option.
Standard controls and signals include remote On/Off, output over voltage, input under voltage and over current protection. An output trim function provides +/- 10% adjustment from stated nominal output on single output models only.
Basic input to output isolation is up to 1500 VAC and input/output to case is 1600 VDC.
The RDC20 and RDC40 series complement the existing line up of RDC30 30 Watt converters.
The RDC series is available from Newark, Farnell, element14, Digi-Key, approved regional distributors, or direct from XP Power and come with a 3 year warranty.
