We are controlling a vibratory conveyor Eriez which is 400vac 2 phase using a variac. The fluctuations in supply voltage mean the unit is constantly driving up and down giving unreasonable wear to the brushes and causing klarge carbon deposits that can short.
I trialed a thyristor unit but the...
We are working on a project an are trying to source a 0-240V, 40A, two phase VFD. So far the electrical engineers have had no success, I thought i'd give this forum a go and see if anyone can help.
