FUJI FVR004G5B-2 Small general-purpose frequency converter

The FVR004G5B-2 is a small general-purpose frequency converter under the FUJI FVR-G5 series, specifically designed for controlling the speed of three-phase induction motors. 

With its precise control and high reliability, it is widely adapted to various industrial automation scenarios.

Core technical parameters

Power and Current

The compatible motor power is 0.4kW and the output current is 3A, which can meet the power control requirements of small industrial equipment.

Voltage and frequency

The input voltage range is single-phase 200-240V, and the output voltage range is 0-400V. The frequency adjustment range is as wide as 0.1-400Hz, which can flexibly adapt to the requirements of different loads for motor speed.

Protection and dimensions:

The protection grade is IP20. capable of withstanding the influence of dust and other factors in conventional industrial environments. The dimensions are 140mm×90mm×75mm, and the weight is approximately 1.5kg. The compact design makes installation easy and saves space.

Overload capacity

It has a strong overload tolerance capacity and can withstand 150% of the rated current for a short period of time, ensuring the stable operation of the equipment during sudden load fluctuations.

Core functions and design

Precise control

By adopting advanced vector control technology and adaptive flux control methods, combined with flexible PWM technology, it can not only achieve precise speed regulation of the motor, but also reduce operating energy consumption and noise.

Anti-interference and protection

Built-in EMC filter, which can effectively suppress grid interference and signal crosstalk; It integrates multiple protection functions such as overload, short circuit and overvoltage at the same time to prevent the equipment from being damaged due to abnormal working conditions.

Strong scalability

It is equipped with an internal RS485 communication port, supporting multi-device collaborative control. The user-friendly operation interface also facilitates integration with industrial systems, making it suitable for complex automation control requirements.

Typical application scenarios

This frequency converter, due to its small size and precise control, is often used in the drive control of small industrial equipment. 

For instance, it can be used for power regulation of equipment such as machine tools, textile machinery, packaging equipment, and food processing production lines.

 It can also be applied to flow and air volume control of small pumps and fans, helping such equipment optimize energy consumption and reduce mechanical wear.
