Controllers for 50Hz and 60Hz, from 0.37kW to 150kW, with different grades of voltage symmetry control. Controllers accelerate starting motors fast. Voltages, depending on the type of controller, are balanced. Start and run capacitors are controlled at zero volt crossings, SCRs and all components last. Full overload protection against locked rotors.
Controllers sense the need for start-, some also for run capacitors to engage. Some use binary coded run capacitors to keep the component count low.
A module allows converters to be assembled fast. Digital controller, capacitors, coils, resistors, all ready to build a converter in minutes
