Specialized сontroller MK 10.7
Product purpose
The MK10.7 controller is intended for use as an embedded, high-performance system for direct digital control of frequency converters, secondary stabilized and autonomous power supply systems. The controller is developed using a dual-core microcontroller that combines the functionality of the DSP core and the versatility of ARM. The controller is optimized to reduce wired connections and provides a direct interface with the inverter switch drivers. The controller is oriented to work in CAN networks.
