Variable frequency drive VFD vector controller Three-phase input 340–440 V Output 0–440 V

1. Reliable operation: All internal components use SMD design, which significantly increases the stability of the VFD.
2. Simple operation: The clear control panel and digital display provide excellent visualization and convenient control.
3. Fast cooling: The extra-large heat sink is also equipped with a low-noise cooling fan, ensuring rapid heat dissipation.
4. Good material: Made from flame-retardant ABS material, this frequency inverter is highly impact-resistant.
5. Safer operation: The premium motherboard provides good protection and high safety for the 380-440V three-phase input and 0-440V output.

Note:

1. Before wiring, please confirm that the input power supply is off. 2. For wiring work, please have it done by professional electrical engineers. 3. The grounding terminal must be grounded. 4. After the emergency stop circuit wiring is complete, be sure to verify that the action is valid. 5. Do not connect the inverter output wire to the casing and do not short-circuit the output wire. 6. Please confirm that the AC main circuit supply voltage is compatible with the inverter's rated voltage. 7. Do not perform a withstand voltage test on the inverter. 8. Please connect the braking resistor according to the wiring diagram. 9. Do not connect the power cord to the U, V, or W output terminals. 10. Do not connect the contactor to the output circuit. 11. Be sure to install the protective cover before powering on. When removing the cover, be sure to disconnect the power. 12. The inverter, when the reset and retry function is selected, must not be located near mechanical equipment, as it will suddenly restart when the alarm stops. 13. After confirming that the operating signal is broken, the alarm can be reset. If the alarm is reset while the operating signal is present, the inverter may start suddenly. 14. Do not touch the inverter terminals, as there is high voltage on them, which is very dangerous. 15. During power-up, do not modify the wiring or disconnect the terminals. 16. Disconnect the main circuit power supply before performing inspection and maintenance. 17. Do not modify the inverter without authorization. 18. Please note that the new and old types of this product will be shipped randomly, and please ensure this is acceptable before ordering.
