RDC40110S12

RDC40 Series DC-DC Power Supplies XP Power 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 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.
