Industrial dc-ac sine wave inverters use high frequency PWM technology

ABSOPULSE CSH-400-F6 series of heavy-duty, high input voltage dc-ac sine wave inverters use microprocessor controlled, high frequency PWM technology to deliver 400VA pure sinewave output voltage. Devices convert 600Vdc industrial input voltage (450V to 800V operating range) to an isolated sine wave output of 115Vac continuous at 60Hz or 400Hz, or 230Vac continuous at 50Hz. Unit’s high frequency conversion enables high efficiency, compact construction of 210 x 64 x 365mm and low weight.  Design topology allows for input voltages of up to 1200Vdc. Devices suit industrial applications that require clean sine wave ac-output voltage. http://www.absopulse.com
