Is the speed adjustment and the dimmers working to change the voltage?
The resistance heating temperature can control the load voltage and also control the load current, which is in accordance with ohm's law. When using induction heating, the frequency can be controlled by temperature. Dc speed control general control voltage (control excitation current adjustment torque), ac speed control general control frequency (control voltage is the regulating torque) The dimmer controls the output current, which is actually a constant current source The above power supply controls the protective signal of the object to the control system to ensure that no further adjustment or failure state is burned
Not necessarily, but also the frequency of change. The equipment is not burned as long as the rated voltage (current) is changed.
The above adjustment is regulated under the rated voltage condition, such as a lamp that can be adjusted to 180V or 130V with a change in brightness. If you go from 220V to 380V, it will burn up. So you need to know the rating of any item to use correctly.
