3AC Vector Frequency Inverter 220V ~ 240V 0.4KW ~ 185KW


The KD330 series inverter is a universal high-performance drive vector control function inverter.


With open-loop vector and V/F control, high-performance current vector control technology can realize asynchronous motor control with its own 485 communication port. The built-in PID makes it easy to implement a closed-loop process control system that can operate up to 16 speeds. With swing frequency and fixed length control, it can be used for driving of textile, paper, wire drawing, packaging, food and various automatic production equipment.
