Quality Variable Frequency Drive Motor Controls Single-phase Speed Controller. This VFD uses unique control method to realize high moment of force, high accuracy and wide speed regulating range driving, with high performance. Fast start and stop response, large moment of force at low speed. Large heat sink + efficient integrated fan, better heat dissipation effect, safer to use. It has good anti-trip performance and ability to adapt to rough power, temperature, humidity and dust interference, greatly improved stability. Simple to operate and wire, connect to wires after removing screws. By optimizing PWM control technology and electromagnetic compatibility, it satisfies users’ requirement of low noise, low electromagnetic interference.
