Overview

3.7kw inverter single phase to three phase with IP20 enclosure, can work at (–10℃, 40℃). PID controller is installed inside, convenient for making closed-loop system. Humidity 5%-95%, without condensation and speed regulation reaches 1:100. With adjustable output frequency, it can be adjusted according to different equipment needs to meet different frequency requirements of the equipment.

Feature

The inverter input voltage is 1 phase 220V AC ±15%, and output voltage is 3 phase AC 0~input voltage.
Come with RS485 communication and enclosure rating IP 20, variable frequency drive single phase to 3 phase has overvoltage protection overload protection, over current protection, etc. Good safety performance and easy to use.
Equipped with a cooling fan, the frequency drive inverter can work at (–10℃, 40℃), and automatic voltage regulation (AVR) keeps constant output voltage when power source voltage varies.

Details

Digital Display

The electronic screen of the 3.7 kw frequency drive inverter displays clear fonts. The digital inverter indicators of the inverter single phase to three phase will display the corresponding inverter operating conditions. It can monitor real-time inverter data changes, and improve safety performance.

Multi-function Button

Equipped with multi-function keys, the 5hp inverter 1 phase to 3 phase has menu/exit, up/down keys, forward and stop/reset. The functional key of the single phase to 3 phase inverter is very convenient to adjust the 3.7kw inverters' parameters and operating status at any time.

Cooling Fan

The intelligent cooling fan installed in the 5hp inverter single phase to three phase introduces cooling air into the frequency inverter. It can reduce the inverter component temperature, protect the devices from damage, and prolong variable frequency inverter's service life.

FAQ

How to test a single-phase to three-phase frequency inverter?

Power supply check: Before turning on the power, use a multimeter or voltmeter to check whether the voltage and frequency of the input power supply meet the specifications of the frequency inverter.
Start the frequency inverter: Start the inverter 1 phase to 3 phase correctly according to the operating instructions of the frequency inverter. Observe the display panel of the inverter to ensure that the display is normal and there are no faults or error messages.
Output voltage and frequency test: Use a multimeter or oscilloscope to measure the output voltage and frequency of the inverter. Make sure the output voltage and frequency are consistent with the set values and are stable without fluctuations.
Load test: Connect an appropriate load to the output end of the frequency inverter and observe the operating status of the frequency inverter. Gradually increase the load, check whether the inverter can work stably, and observe whether the output voltage and frequency change.
Functional test: Test various frequency drive inverter functions, such as speed regulation, forward and reverse rotation, protection, etc. Make sure these features are working properly and as expected.
Abnormal test: simulate some abnormal situations, such as input voltage being too high or too low, load short circuit, etc., to check whether the inverter can respond correctly and take corresponding protective measures.

Great vfd for a home lathe

This unit was basically pre-configured and ready to go to simply power a single-phase motor for a small lathe or similar application. If you want to do more, most of the time you can change a few pre-set variables in a few minutes. So far, very quiet, very reliable!

Works great and runs quietly

Very easy too install and setting up parameters was as simple as it gets. Works great and runs quietly. I have been running one unit for 5 months now everyday and not a single issue. I will recommend this 3.7kw single phase to three phase frequency inverter to my friends.

Good three-phase inverter

This inverter borrowed from a neighbor's house is very easy to use. It has very powerful functions. I like the advantage that it can save energy. It will not use much energy for a long time. It really saves the cost of the family. Also buy one from the inverter online store.
