Drive cabinet with 400 kW converter
Constructor: Mariusz Szlendak
PZN-400kW type AC drive unit designed for supplying and smooth speed control of 3-phase 400 kW asynchronous motors.
We have been manufacturing drive cabinets since the beginning of the company’s activity. Initially, they were based on thyristor systems. Along with the development of drive technology we started to use the inverters developed by us. Currently, we use vector inverters types MFC710 and MFC710/AcR to enable energy return to the mains.
The presented system was made for the G-Drilling company from Warsaw, which implemented the investment for Geotermia Konin.
