Miniature inverter, three-phase, pmax=0.75 kW, uwe=3x400 V AC, iwe=4.3 A, uwy=3x400 V AC, iwy=2.5 A FA-3HS-007

Compact three-phase inverter for precise motor control

This miniature three-phase inverter FA-3HS-007 is an advanced solution for controlling electric motors. Designed for both professional installers and end-users, it offers reliable operation and a wide range of functions in a compact housing. A rated power of 0.75 kW makes it ideal for use in light industry, construction, and various automation applications.

Functionality and communication

The FA-3HS-007 inverter stands out with a rich set of communication interfaces, enabling integration with control and monitoring systems. It has 5 digital inputs, 1 digital output, 1 analog input, and 1 analog output. Support for the Modbus protocol allows for easy data exchange with SCADA and PLC systems. Additionally, it is equipped with an RS-485 interface, which expands the device's communication capabilities. The lack of support for more advanced communication protocols such as LON or PROFINET does not limit its functionality in typical applications.

Construction and operating parameters

The housing with dimensions of 72 x 138 x 123 mm provides adequate protection against environmental conditions (IP20 protection class). The inverter operates at a supply voltage of 3x400 V AC and an input current of 4.3 A, delivering an output voltage of 3x400 V AC with a current of 2.5 A. The integrated braking module (chopper) increases operating efficiency and allows for smooth motor stopping. The device is designed to operate in an ambient temperature from -10°C to +40°C. Thanks to the ability to operate at a frequency of up to 300 Hz, it offers great flexibility in adapting to different applications. The relative tolerance of the mains voltage is 10%, and the mains frequency is also 10%, which ensures stable operation even with fluctuations in supply parameters.
