Compact 3-Phase Vector Frequency Converter - 4KW VFD Inverter for 340-440V to 0-440V

This variable frequency drive is constructed from industrial-grade ABS plastic that is flame-retardant, highly impact-resistant, and heat-resistant. The internal components feature a modular design, significantly enhancing the overall stability of the machine. The drive utilizes a super-sized heat sink and a compact cooling fan, ensuring excellent heat dissipation with low noise levels.

The drive comes equipped with a user-friendly keyboard and a digital display screen, providing maximum convenience for operators. It features a RS485 communication interface, enabling parameter settings and other operations.

In terms of specifications, this variable frequency drive has the following features:

Item Type: Variable Frequency Drive Material: ABS Storage Temperature: -25°C to +55°C Input Voltage: Three-phase 340-440V AC, 50-60Hz Output Voltage: Three-phase 0-440V AC, 0-400Hz Output Current: 9.4A

The drive includes a built-in braking unit that can be connected to an external braking resistor for emergency stop purposes. The recommended braking resistor has a power rating of 500W and a resistance of 150Ω.

The package contents include: 1 x Variable Frequency Drive 1 x User Manual

It is essential to adhere to the following safety instructions:

1. Before wiring, ensure that the input power supply is turned off.
2. The wiring operation must be performed by professional electrical engineering personnel.
3. The grounding terminal must be properly grounded.
4. After completing the emergency stop circuit wiring, verify that the action is effective.
5. The output lines of the frequency converter must not be connected to the housing or short-circuited.
6. Confirm that the AC main circuit power supply voltage matches the rated voltage of the frequency converter.
7. Do not perform voltage withstand tests on the frequency converter.
8. Connect the braking resistor according to the wiring diagram.
9. Do not connect the power cord to the output U, V, W terminals.
10. Do not connect a contactor to the output circuit.
11. Install the protective cover before powering on, and disconnect the power supply before removing the cover.
12. Select a frequency converter with reset and retry function, and keep it away from mechanical equipment, as the alarm may restart suddenly when it stops.
13. The alarm can only be reset after confirming that the operation has been cut off. Resetting the alarm while the system is still in operation can lead to sudden startup.
14. Do not touch the terminals of the converter, as they carry high voltage and pose a severe hazard.
15. Do not change wiring or disassemble terminals while the power is on.

By adhering to these guidelines, users can ensure the safe and reliable operation of this variable frequency drive.
