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. 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. Easy to Operate: It adopts humanized keyboard design and reasonable layout, which is 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. High Anti-jamming Capability: It meets users' requirements by optimizing PWM control technology and electromagnetic compatibility. So it can meet your requirements for low noise and low electromagnetic interference. Application This frequency converter is suitable for motors, drilling machines, pumps, fans, coolers, compressors, and other industrial machinery.
