Motor moves the autotransformer ARC, in order to increase or decrease the voltage, by moving the carbon brush to left or right. |
If this is actually an autotransformer, then you do not have a separate primary and secondary winding. |
I am planning to build a 4 input volume control device using an autotransformer and remote control. |
To protect your audio components, it is equipped with autotransformer impedance matching systems. |
Always connect the autotransformer after the power switch and fuse of the equipment it is installed in. |
The auxiliary supply input can be wired between two 230 V phases at the autotransformer output. |
