three-phase 6-12KW integrated board
1.1 Product Introduction General Description
This controller adopts the design of main control, drive and EMC filter integration, which is convenient for users to install. Drive with 180
degree sine wave vector control technology, weak magnetic control technology, MTPA current control technology, with module temperature protection, input and output over
flow protection, compressor demagnetization protection and other functions, specially used for DC inverter compressor drive, the use of only external matching reactance
and several temperature sensors can be applied to the control of the whole refrigeration system.
1.2 Product Features Features
1, wide voltage operation, stable operation in the voltage range of 300V ~ 460Vac
2, integrated design of main control, drive (press & DC fan) and EMC filter, miniaturization, high integration, convenient integration
machine
3. Closed-loop start control technology to make the compressor start smoothly and reduce the starting current of the compressor
4, weak magnetic control & MTPA control technology, improve the maximum operating range of the compressor speed, improve the output capacity
5,180 ° SVPM sine wave control to reduce output current harmonics, motor vibration, torque ripple and noise
6, with over and under voltage (input & DC bus), over and under current (input & output), output phase loss, out of step, over temperature and other protection functions
