Metal-cased converter complies with railway transient and EMC standards



Designed specifically for railway applications, the RDC30 series of highly-efficient metal-cased isolated 30W DC/DC converters from XP Power accommodate a wide input range based around the popular railway input voltages of either 72 (36-140) VDC or 110 (55-176) VDC. The converters are available with single, dual or triple outputs and conform to the railway industry transient standards EN50155, NF F 01-510 and RIA12. The single-output models provide the standard regulated output voltage of 3.3, 5, 12 or 15 VDC, and duals provide 5, 12 or 15 VDC. Triple-output models provide a 3.3 VDC output with either 12 or 15 VDC outputs, or a 5 VDC output with either 12 or 15 VDC outputs. These convection-cooled converters have an efficiency rating of up to 91%, and deliver a power density of 37.5 Watts per cubic inch from their compact package that measures 1 x 2 x 0.4 inches (25.4 x 50.8 x 10.16 mm). When convection cooled the operating temperature range is from - 40 degrees C to + 75 degrees C. An optional heatsink extends this up to + 80 degrees C. Maximum case temperature is + 105 degrees C. 1500 VAC Basic isolation between input and output, and 1600 VDC between input/output and the metal case is provided across the range. The RDC30 series complies with the internationally recognized EMC standard EN50121-3-2 as required for railway applications and rolling stock apparatus. A remote On/Off function gives external control of the output while a trim input provides the capability to adjust the output voltage 10% of the nominal output voltage. In addition to the 30 Watt RDC30 series, XP Power's DC-DC converter line-up for railway applications includes the RDQ100/150 series of 100 Watt and 150 Watt base plate cooled converters. The RDC30 is priced at $81.90 for single output models in 500 pcs quantities. XP Power
