Railway inverters deliver 3-phase pure sine wave output

ABSOPULSE  CTP-300R-F7 Series 3-phase 300VA sine wave inverters for railway applications meet the stringent requirements of EN50155 for electronic equipment used on rolling stock. Devices deliver a 3-phase output of 208Vrms, line-to-line, at 60 or 400Hz. A 115Vrms phase-to-neutral output can also be used. Products operate from wide EN50155 input ranges of 24Vdc (17-34V), 36Vdc (25-51V), 48Vdc (33-67V), 72Vdc (50-101V), 96Vdc (67-135V) or 110Vdc (77-154V).  http://www.absopulse.com
