12v cc regulator
My dear Jose Miguel already saw it and I find it interesting, what is not clear to me is how to adjust the regulator, do you have any idea? The instructions on the page are not very clear, which is apparently regulated with a resistance, isn't it? and about the use is more or less this: I have lap top chargers (18v 3.3amp) that I want to use to power 24 "LCD screens (12v 3.0amp) so would the use of the LM338 be appropriate?
The output voltage is adjusted by a potentiometric trimer of 5k ohms. which appears in the scheme as R2.
He had the scheme somewhat clearer.
The consultant clearly says that he wants to go from 18 volts to 12 volts so there will not be much power dissipation.
It will be 6 volts of difference by 3.3 amps gives us 19.8 watts which is more than reasonable.
I had not visualized the 18V data, the apologies .... I also insist with my opinion, it all depends on the use, in facilities where the W consumed must be optimized, 20W in the form of heat may be unacceptable or not. Today, voltage regulating modules with high energy efficiency at very low cost are available on the world market (generally and with exceptions) Ex: https: //articulo.mercadolibre.com.ar/MLA-768446361-xl4005-step-down -convertidor-dc-dc-5a-source-08-a-24v-_JM Regards.
Thank you very much to all I stay with the recommendation of Jose Miguel ..
Now, to get to work!
THANK YOU!
There are no problems, here we are to propose different solutions if there are any and the participant decides and stays with the last word of what he wants to do since he will have to deal with the consequences like everything in this life .... Luck and good accomplishment of the project. Ric.
