Features It has good anti-trigger performance and ability to adapt to power, temperature, humidity and dust interference, greatly improved stability. By optimizing PWM control technology and electromagnetic compatibility, it meets users' requirements for low noise and electromagnetic interference. This VFD uses a unique control method to realize high force moment, high accuracy and wide range of speed regulation, with high performance. Designed with large heat sink for better heat dissipation. Simple to use and wire, connect to the wires by screw terminals which are more convenient.
