RDC40

RDC40 Series DC-DC Power Supplies 40 Watts 72 & 110 VDC Input for Railway Applications Single and Dual Outputs 1500 VAC Basic Isolation High Power Density High Efficiency Up to 90% Remote On/Off 3 Year Warranty The RDC40 series of 40W DC-DC converters are designed for railway applications and comply with EN50121-3-2, the EMC standard for rolling stock apparatus. There are two input voltage ranges. 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 -40°C to +85°C and a maximum case temperature of 105°C.
