Features 【Stable Performance】This VFD variable frequency drive: 1-phase input, 3-phase output. Adaptive motor power: 2.2kW. Using a unique control method, the drive with high torque, high precision and wide speed range is realized. It has good anti-tripping performance and the ability to adapt to harsh power, temperature, humidity and dust interference, which greatly improves the stability. 【Low Noise】By optimizing PWM control technology and electromagnetic compatibility, it meets the user's requirements for low noise and low electromagnetic interference, and provides you with a quiet operating environment. 【Multiple Protection Functions】It has multiple protection functions such as over-current protection, over-voltage protection, over-heat protection, overload protection, and intelligent power module protection. With a large heat sink design, there is enough cooling space between the electronic components and the chassis, and the heat dissipation effect is better. Safe and durable. 【Easy to Operate】Simple operation and wiring, it is more convenient to connect to the wires through screw terminals. Please note: When adjusting parameter, the VFD must stop working, otherwise it will not be able to save parameter setting. 【Wide application】The frequency conversion single to three phase is widely used in various types of automatic control equipment, such as: fans, water pumps, compressors, spindle motors, drilling machines, three-phase motors and other machines.
