Re: [CAD_CAM_EDM_DRO] Re: Power Supply-- more questions

Bob, I got reading your white page about power
supplies and what not that you sent me a link for.
In it you state that you used a Plitron Toroid
transformer # 077015201 This unit is rated at 22V
and 6.28A, however in your text you noted that it
will produce 13.26A [ ish] so.. I'm wondering if
it had two leads which you could connect to double
the current? If so.. then spec'ing a Toroid from
them just got a whole lot easier.

Thanks!
Jarrett
