Miniature inverter, three-phase, pmax=4.0 kW, uwe=3x400 V AC, iwe=10.5 A, uwy=3x400 V AC, iwy=9.0 A FA-3HS-040

Compact three-phase inverter for precise motor control

This miniature three-phase inverter FA-3HS-040 is an advanced device designed for smooth speed control of induction motors. It provides optimal control over industrial and commercial processes while offering compact dimensions and easy installation. A maximum power of 4 kW makes it an ideal solution for various applications, from controlling pumps and fans to production machinery.

Flexibility and communication for modern installations

The FA-3HS-040 inverter stands out with a rich set of communication interfaces, including RS-485 with Modbus protocol support. This enables integration with automation systems and remote monitoring of operating parameters. Additionally, it has 5 digital inputs and 1 digital output, as well as 1 analog input and 1 analog output, which increases its functionality and allows it to be adapted to specific application needs. The IP20 protection degree ensures safety in working conditions with limited exposure to moisture and dust.

Construction and application – robustness and versatility

The device dimensions (72 x 185 x 134 mm) allow for mounting in a limited space. The integrated braking module (chopper) increases energy efficiency and improves engine dynamics. The inverter is adapted for operation both in industry and in residential and commercial buildings. The maximum output frequency is 300 Hz, which allows for precise adjustment of the motor speed to the requirements of a specific process. The rated output current I2N is 9A at 400V, ensuring stable operation even under heavy load. A relative network voltage tolerance of 10% guarantees reliable operation even with voltage fluctuations in the power supply network.
