Three-phase frequency converters

Higher performance is offered by three-phase frequency converters for voltage, which are used to control and operate machines and equipment with higher power consumption. You can choose from converters with power from 0.4 kW up to an impressive 22 kW. In addition to the built-in PID controller, some three-phase frequency converters are equipped with a macro PFC (pump and fan control) function for utilizing pre-programmed activities with applied macros and an intuitive user interface, which, in cooperation with the assistance display, speeds up and significantly simplifies the installation of the converter, selection of desired parameters, and comprehensive commissioning of the converter. The braking chopper is integrated, so no additional space or installation time is required. Frequency converters are cooled by their own built-in fan, which draws cooling air from the surrounding environment, so it is necessary to ensure that the cooling air does not contain corrosive components and does not exceed a temperature of 40 degrees Celsius (or 50 degrees Celsius at reduced performance). Even with these powerful three-phase converters, it is advisable to use a special Flash Drop device for selecting and detailed setting of operating parameters, which can be found in the "accessories" category.
