ABSOPULSE ELECTRONICS BAR 250R-D3 series of RIA12 dc-dc converters deliver up to 250W output power in railway rolling stock applications. Units provide input voltage surge-withstand capacity 3.5 times nominal input voltage for 20 milliseconds and meet the requirements of RIA12 with wide margins. RIA12 is the general specification for protection of traction and rolling stock equipment from transients and surges in dc control systems. Units operate from 36Vdc, 48Vdc, 72Vdc, 96VDC or 110Vdc, with wide EN50155 input ranges. At 24Vdc input, the units are derated to 200W. Products deliver 12Vdc, 24Vdc, 48Vdc or 110Vdc. Custom input and output voltages are available on request.
