30 W DC-DC Converter Complies with Railway Transient and EMC Standards

The RDC30 series DC-DC converter from XP Power produces up to 30 W and is designed for railway applications.  

The RDC30 series of highly efficient metal cased and isolated 30 W DC-DC converters from XP Power are designed specifically for railway applications. Accommodating a wide input range based around the popular railway input voltages of either 72 (36 to 140) VDC or 110 (55 to 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 °C to + 75 °C. An optional heat sink 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.
