1)The input voltage, output voltage, frequency and phase can be custom made. 2)Two kinds of start mode: Step Down Voltage Start and Variable Frequency Start. VFD is especially used for taking 3 phase inductive load more easily. This function is very convenient for users and also reduce frequency converter’s usage, which reduced the cost of equipment investment, easy to connect wires and control. 3)Output AC Power is suitable for all types of home appliances,electric tools, electric motors etc. 4)Using the fifth generation efficient IPM intelligent module from Japanese Mitsubishi, high efficiency and stable performance. It with powerful protection function for short circuit, over load, over temperature. Service life can reach 15-20 years. www.cnsandi.com
