Description This is a 2.2kw three-phase frequency converter that can steadily control the motor to keep it running well. It can steadily convert the current frequency to regulate the speed of your motor and ensure more accurate and fine processing. Application This frequency converter is suitable for motors, drilling machines, pumps, fans, coolers, compressors, and other industrial machinery. Key Features Three-phase Input and Output: This frequency converter with three-phase 380V input and three-phase 380V output can better meet your usage needs. Stable Operation: The motherboard that has been painted three times can also avoid temperature, humidity and dust, and other interference, so it offers you a stable operation. Support External Resistor: The converter has a braking function and supports an external resistor. But it also can be used directly without the external resistor. High Torque: This converter has high torque and fast response so that it can output stable frequency to ensure stable motor speed. Moreover, its torque can be automatically compensated to meet various processing needs. Easy to Operate: The digital display with indicator is intuitive and clear to show the machine voltage, frequency, and other values, making you operate it more accurately. It meets users' requirements by optimizing PWM control technology and electromagnetic compatibility. Safety Protections: This frequency converter has a variety of built-in protection functions, such as overload protection, overcurrent protection, overvoltage protection, and overheating protection. Good Heat Dissipation: The built-in heat dissipation fan and the heat dissipation holes in the housing can dissipate heat inside the machine in time and prolong the service life of the machine. Details Mounting Rail: There is a mounting rail on the back of the frequency converter to make it easy for you to mount it on the wall. Knob: The knob allows you to precisely and infinitely adjust the output frequency. Wiring Letters: In order to avoid wrong wiring, the output and input wiring ports are printed with letter markings.
