Variable Frequency Drives Tripe Phase 400v 0.4-800kW

NK300 serial variable frequency drive incorporates perfectly the optimized asynchronous driving and years of experience; it is born for asynchronous driving motors!

NK300 variable frequency drive is built on TI’s powerful DSP-based motor control chip, with the adoption of the sensorless current vector control (SVC) and open-loop torque control (TC). NK300 can be widely used for the asynchronous motor driving where better speed control and low-frequency torque are required.
