Features

• IEC/EN 60950-1, UL/CSA 60950-1 2nd Ed. 144W to 288W Railway Standard Isolated DC-DC Converter HR Series. The Power-One HR Series of DC-DC converters offers a range of railway power supplies for use in transportation and other advanced electronic systems. These DC-DC converters feature a wide input voltage, very high efficiency, high reliability, low output voltage noise and excellent dynamic response to load/line changes. The HR series of DC-DC power supplies can be connected to all conventional railway batteries. LED indicators display the status of the DC-DC converter and allow for visual monitoring of the system at any time. The Power supply can be plugged into a 19 inch rack system or be chassis mounted. The DC-DC converters are particularly suitable for railway applications and can be supplied by all common railway batteries. Extremely wide input voltage range from 12 to 168 VDC in the same model RoHS compliant Class I equipment Compliant with EN 50155 and EN 50121-3-2 Input over- and programmable under-voltage lockout Shutdown function Inrush current limitation 10 ms hold-up time Adjustable output voltages 2 independent, isolated outputs: no load, overload, and short-circuit proof Rectangular current limiting characteristic Parallel operation with active current sharing Very high efficiency up to 94% Immunity according to IEC 61000-4-2, -3, -4, -5, -6 ALL PCB boards protected by lacquer Very high reliability
