about DC and AC constant current source with 700mA - 1500mA ? Thanks Title: Re: DC and AC constant current sources Post by: chandra2sekhar2000 on November 13, 2007, 03:58:51 15:58 hello !
what voltage u required ? and for what purpose? Title: Re: DC and AC constant current sources Post by: free on November 13, 2007, 11:25:42 23:25 I use 12v.
Using for measure conductivity of the rocks. Title: Re: DC and AC constant current sources Post by: greywolf on November 14, 2007, 01:03:24 01:03 Free,
Have a look at the sites listed below. They should point you in the right direction to design your own DC constant current circuit. http://en.wikipedia.org/wiki/Current_source http://michaelgellis.tripod.com/howland.html http://schematics.blogspot.com/2005/04/constant-current-source.html http://users.pandora.be/davshomepage/current-source.htm greywolf Title: Re: DC and AC constant current sources Post by: AntiBG on November 20, 2007, 11:50:59 23:50 view this pdf:
