Dc/dc converters suit railway applications

The VQB100R and the VHB150R series of board mount dc/dc converters target railway, telecom and battery-powered applications, and help comply with the EN50155 standard. The internally potted and encapsulated design protects against dust, moisture, and shock and vibration.

The board-mount dc/dc converters are offered in industry standard quarter brick and half-brick footprints. The 100 W VQB100R quarter-brick and the 150 W VHB150R half-brick converters provide 92.5% efficiency. They provide a 3:1 input range from 66 to 160 Vdc and output voltage options of 5, 12, or 24 Vdc. They operate from -40° to 100°C and provide 2,250-Vdc I/O isolation. ($119 ea/100 —available now)
