[GreenKeys] Loop Power Supply For Use On Model 28KSR - Question

[Keith Lueck]

 Hi Mark -
Certainly not with the usual constant voltage supply and series resistor.  I've operated a model 15 using a constant *current* supply with ~43V of compliance (the maximum voltage available) - this was at 60 wpm.  I never turned the voltage down to see what the practical lower limit was.  If you wanted to run 100 wpm, it would probably take a higher voltage...  
Cheers,
Keith

 Greetings To One And All !     Although I have not yet performed any experimentation, prior to doing so, I thought it may be a prudent idea to simply inquire first, prior to spending any amount of time, needlessly, as I am certain that, surely, one of you guys probably knows the answer already to my question:  Is it possible to correctly operate a Model 28KSR utilizing a 30 Volt, 60 milliamp loop supply ? Is 30 volts enough to properly operate the selector magnets for proper operation ?     Thank you in advance for any assistance !73, Mark, WN3SIX______________________________________________________________
