Beijing Leader & Harvest Electric Technologies Co., Ltd.

Company Brief: Leader & Harvest is a professional variable frequency drive manufacturer in China, providing VFD, which is also known as AC driver and medium voltage frequency inverter. Variable frequency drive is mainly used for adjusting or changing the frequency of alternating currents applied to electrical motor. Our VFD systems are available in different voltage and current ratings. The voltage range is of 3.3kV, 4.16kV, 6.6kV, 10kV and even higher. With the features of stable performance, high efficiency, safe and reliable use, as well as environmental protection and energy saving, our frequency converters are increasingly used in a wide range of industries, such as electric power, metallurgy, petroleum, petrochemistry, cement, mining, and more. VFD is especially used for controlling motors equipped in discharge fan, water pump, air compressor, etc.
