690V/1140V Frequency Inverters

This series of four-quadrant variable frequency drives is available in 690V and 1140V voltage ratings with a maximum power output of 1000kW. Featuring energy feedback capabilities, the drives can recover and reuse over 95% of regenerative electrical energy. They employ comprehensive protection technologies against over-temperature, over-voltage, and over-current conditions, while offering low noise, low harmonic pollution, and a high power factor. Primarily designed for explosion-proof applications in the coal mining industry, they are suitable for driving equipment such as mine hoists, belt conveyors, personnel transport systems (man-riders), and shearer traction drives.
