Power-One has announced the availability of two DIN-Rail mount converters, designed specifically to meet the rigorous requirements of rolling stock applications. The EWR1601-6 and EWN2660-6 operate from a 66 to 154VDC input range and combine EN50155 compliance with the field-proven reliability of Power-One’s W-Series converters - further extending Power-One’s extensive range of power conversion solutions designed for railway applications.

The W-Series can operate in ambient temperatures ranging from -40 to 60°C with only convection cooling. Reliable operation in rugged environments is also ensured by pollution degree three rated clearances and creepage distances, and printed circuit boards that are coated with a protective lacquer. Compliance to EN50155 provides exceptional immunity to input transients and surges.

Peak-load capabilities of 150% accommodate the high start-up current requirements of motors, solenoids, and lighting. The EWR1601-6 provides a single 5-amp output. The EWN2660-6 provides two independently-regulated 5-amp outputs; parallelable to provide 10 amps per converter. Up to three converters can be paralleled to provide 30 amps.

These 35mm DIN-Rail mount products are designed for quick installation and reduced maintenance. Easy-access front-mounted cage-clamp terminals utilize screw terminals for use with pre-assembled harnesses. Interface options, including save-data signals and output-voltage adjustment interfaces, facilitate remote monitoring and control. Extremely low inrush currents reduce nuisance maintenance calls for tripped breakers and fuses.

Additional features include: compact 113.6 x 138 x 108 mm (4.5 x 5.4 x 4.25 in) overall dimensions, up to 89% efficiency, and front-mounted operating status LED. EWR1601-6 pricing is $155.00 each in quantities of 500 pieces. EWN2660-6 pricing is $210.00 each in quantities of 500 pieces. Production quantities are typically available in four to six weeks.
