I use 24 volt "wall wart" DC adapters, which, with the negligible load of a CS generator, put out about 30 volts. Of course, the constant current regulator automatically adjusts the voltage across the electrodes to maintain the constant current. I estimate after 24 hours with 5.5" #12 silver wires spaced about 2 inches, the PPM is around 12.
I like the LM337s because they allow setting the current with a single resistor. The constant current diodes someone else mentioned work fine, but they are fixed current, cannot be adjusted, and cost a lot more than the LM337 does. --Steve Y. ----- Original Message ----- From: "Nessie" <[email protected]> To: <[email protected]> Sent: Thursday, November 10, 2005 6:24 PM Subject: Re: CS>Ole Bob's Constant Current CS Generator > Sooooooooooooooooo: > > What is the voltage.
