DANAHER MOTION 146U-3 / 146U3

DANAHER MOTION 146U-3 / 146U3 

DANAHER MOTION 146U-3/146U3 is not a transformer in the traditional sense. From its electrical parameters, working principle, and application scenarios, it focuses more on the field of motion control, mainly used for precise control of equipment motion, such as displacement of robotic arms, feed of machine tools, etc. It has a fundamental difference from the functions of transformers used for voltage conversion and power transmission distribution. However, in practical industrial application scenarios, DANAHER MOTION 146U-3/146U3 may work in conjunction with transformers. For example, in industrial automation production lines, transformers can provide suitable voltage for the entire system, and DANAHER MOTION 146U-3/146U3 achieves precise motion control of production equipment based on this stable power supply.
