Product Details

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.
