Details

Air Vents

Equipped with multiple vents and built-in cooling fans, the 0.4 kw variable frequency inverter can keep the temperature inside the inverter stable. The internal cooling fan cools the drive's internal components and forces air circulation to accelerate heat dissipation.

Aluminum Sheet

The heat sink aluminum sheet of the 0.4kW inverter is a necessary heat dissipation material, which is used to regulate the high frequency inverter's internal temperature of the inverter, protect the circuit board from heat damage, and ensure the normal operation of the inverter.

LED Display

The LED screen of the 0.4kw frequency inverter can display the real-time running status to facilitate parameter setting and adjustment, provide alarm and fault information to prevent damage to the vfd inverter, and prolong the service life of the 1/2hp inverter.

This frequency inverter does not control the reverse operation of the motor, if you want to reverse operation, please refer to the motor nameplate instructions.

FAQ

How to wire a single-phase inverter to a motor?

Connect the power supply: connect the firewire (usually red or brown) of the single-phase power cord to the L1 terminal of the inverter and the zero wire (usually blue or black) to the L2 terminal of the inverter. Make sure the connection is secure and be careful not to short-circuit.
Connecting the motor: Connect the power cord of the single-phase motor to the output of the variable frequency inverter. Usually, the firewire of the motor is connected to the U terminal of the vfd inverter, and the zero wire is connected to the V or W terminal of the inverter.com (the specific connection may vary depending on the model of the inverter, please refer to the manual of the inverter).
Connect the control line (if necessary): if you need to use external control equipment (such as PLC, touch screen, etc.) to control the inverter, connect the corresponding control line to the control terminal of the inverter.
Connect the grounding wire: Connect the grounding wire of the inverter to the grounding terminal to ensure safe grounding.
Check the wiring: After the wiring is completed, carefully check whether all connections are firm and reliable to ensure that there is no miswiring or short-circuiting.
Starting and debugging: After making sure that the wiring is correct, turn on the power switch of the frequency inverter, and start and debug according to the operation steps in the manual. Observe the running status of the motor to ensure normal operation.

An inverter that has great performance for the price!

This 0.4 kW single-phase output frequency inverter has been working flawlessly. The LED screen is clear and easy to navigate. It's perfect for small motors, though I wish it had a bit more power for larger applications. Overall, it’s solid and affordable.

Efficiency at Low Loads

Inverters are generally less efficient at low loads. Users with occasional or light power requirements should consider the inverter's efficiency at low loads to avoid unnecessary energy losses.
