Industrial frequency converter

Educationally adapted, industrial frequency converter with voltage link for the generation of three-phase, frequency and amplitude variable output voltage from single-phase AC mains. This device can be used for speed open loop control and speed and torque closed loop control of asynchronous machines and IPM machines of the power class 0.3 kW. Front panel with block diagram showing various functions of the inputs and outputs.

Inverter control principle: U / F or DANFOSS-VVC +

The adaptation of the drive machine and the control devices via an extensive set of parameters. This can be easily programmed and optimised via the DANFOSS software MCT10 via the integrated USB port.
