This Variable Frequency Drive is made of high quality shell material, heat resistant and flame retardant. Humanized keyboard design, easy to operate. Digital display screen makes it convenient to read clearly. High efficient fan has the best heat dissipation effect.Features:This VFD uses unique control method to realize high torque, high accuracy and wide speed regulating range driving, with high performance. It has good anti-trip performance and ability to adapt to rough power, temperature, humidity and dust interference, greatly improved stability. By optimizing PWM control technology and electromagnetic compatibility, it satisfies users' requirement of low noise, low electromagnetic interference. Over current, over voltage, over heat, overload, under voltage, intelligent power module protection. Simple to operate and wire. Fast start and stop response, large torque at low speed.
