second generation single-phase 5.5KW integrated variable frequency drive

This controller adopts the design of main control, drive and EMC filter integration, which is convenient for users to install. The driver adopts 180-degree sine wave vector control technology, weak magnetic control technology and MTPA current control technology. It has the functions of module temperature protection, input and output overcurrent protection, compressor demagnetization protection, etc. It is specially used for driving DC inverter compressor. When in use, it can be applied to the control of the whole refrigeration system only by external matching reactor and several temperature sensors. This motherboard can be equipped with 4G Internet of things module, through the background operation, the unit can be parameter query, parameter setting, program upgrade and other functions.
