DC-DC Power Supplies RDC40 Series 40 Watts 72 & 110 VDC Input for Railway Applications Single and Dual Outputs 1500 VAC Basic Isolation High Efficiency - Up to 90% Remote On/Off Complies with EN50155 EN50121-3-2 EMC for Railway Applications 3 Year Warranty Dimensions: The RDC40 series of 40W DC-DC converters are designed for railway applications and comply with RDC40: EN50121-3-2, the EMC standard for rolling stock apparatus. There are two input voltage ranges. 2.00 x 1.60 x 0.4 (50.8 x 40.6 x 10.16 mm) The 72 VDC nominal models accept an input from 36 to 140 VDC and the 110 V nominal versions have a 55 to 176 VDC input. A trim pin allows a +/-10% adjustment for single output models. Using convection cooling the converters have a wide operating temperature range of -40C to +85C and a maximum case temperature of 105C.
