Re: [CAD_CAM_EDM_DRO] Where to buy non induction resistors

Roger,
I hope you have lots of $$$$ for those resistors.
I would be far cheaper to switch to biplor chopper.
The I sense resistors are also non-ind but, much smaller
in value and size.
You get max speed and efficiency. Very little wasted power.
