Using the fifth generation efficient IPM intelligent module from Japanese Mitsubishi, high efficiency and stable performance. It with powerful protection function, the protection for short circuit, over load, over temperature is more safe and reliable. It’s service life can up to 15 years or more. Intelligentized, modularized, simple structure design with powerful function. Two kinds of start mode: Step-down Voltage Start and Variable Frequency Start. Customers can set start mode according to the type of their load. 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. The output frequency can be setting via LCD panel, it’s very convenient for customer. The output voltage can be set between -40 % to +20 % of rated voltage. And the output voltage is very accuracy ±1%.
