Feature: 1. Excellent Material: Variable frequency drive controller is made of excellent ABS and aluminum alloy, which is durable and long service life. 2. PWM Control: Variable frequency drive meets the user's requirements for low noise and low electromagnetic interference by optimizing PWM control technology and electromagnetic compatibility. 3. Fast Heat Dissipation: Frequency converter with fast cooling radiator, intelligent start and stop, and aluminum alloy radiator can achieve faster heat dissipation speed. 4. Superior Performance: The inverter adopts a unique control method to realize the drive of high torsion, high accuracy and wide speed regulation range, with superior performance. Inverter has good anti trip performance and the ability to adapt to rough power, temperature, humidity and dust interference, which greatly improves the stability. 5. Widely Used: Variable frequency drive controller is widely used in motors, mixers, ball mills, water pumps, cranes, conveyors, air compressors, fans, CNC machine tools, etc. Specification: Material: ABS and aluminium alloy Input Voltage: 220 to 240V Output Power: 0.75KW Output Current: 4A Output Frequency: 0 to 999HZ Application Machines: Motor, mixer, ball mill, water pump, crane, conveyor, air compressor, fan, CNC machine tool, etc How to Use1. Before wiring, please make sure that the input power is in a power off state. 2. Please ask a professional electrical engineer to carry out the wiring work. 3. Please make sure that the grounding terminal is grounded. 4. After the emergency stop circuit is wired, please check if the action is effective. 5. The output line of the inverter must not be connected to the shell, and the output line must not be short circuited. 6. Please make sure that the voltage of the AC main circuit power supply is the same as the rated voltage of the inverter. 7. Do not conduct voltage withstand tests on the inverter. 8. Please connect the braking resistor according to the wiring diagram. 9. Do not connect the power cable to the output U, V and W terminals. 10. Do not connect the contactor to the output circuit. 11. Be sure to install the protective cover before powering up. When removing the cover, be sure to disconnect the power supply. 12. Do not use the inverter with the reset and retry function near mechanical equipment. This is because it will suddenly restart when the alarm stops. 13. Make sure that the alarm is reset only after the operating signal has been cut off. If the alarm is reset in the running signal state, the inverter may start suddenly. 14. Do not touch the terminals of the inverter, they are very dangerous due to the high voltage. 15. Do not change the wiring or dismantle the terminals while the power is on. 16. Cut off the main circuit power before inspection and maintenance. 17. Do not modify the inverter without permission.. Package List: 1 x Variable Frequency Drive Controller
