50W isolated DC-DC converter Ultra-wide input and regulated single output
Description
URF1D_QB-50WR3 series is a high-performance product spec
calydesignedfor avariety of railway applications. The DC-DC converters feature 50W output power with no requirement for minimum load, wide input voltage from 43-160VDC, and allowing operating temperature as high as 105C. The products also provide input under-voltage protection, output over-voltage, short-circuit and over-temperature protection. Addtional functions include remote On/Off control,remote sense compensation and output voltage trim adjustment. EN5015 approved and they are widely used in railway systems and a sociated equipment.

N ① Use“H”suffix for heat sink mounting. We recommend to choose modules with a heat sink for enhanced heat dissipation and applications with extreme temperature requirements; ② Exceeding the maximum input voltage may cause permanent damage. ③ Use ”A5”suffix for chassis mounting and“A6”suffix for DIN-Rail mounting. The minimum input voltage range and the start-up voltage of the A5/A6 product model are 1VDC higher than the horizontal package; ④Efficiencies for A5 /A6 Model’s is decreased by 2% due to the input reverse polarity protection function. |
