en belastning.

Hvis du ikke skal arbejde ind i en enkelt belastning, men kan dele det  

moduler, der forsyner hver sin del. Var det ikke lysdioder?

ind og ud.
Jeg har alle almindelige regulatorer - 78xx, LM317 og endda LM338.

og:
http://adjustablevoltagepower.blogspot.dk/


Den anden bruger en LM317, men benytter den som variabel regulator.


De 2 andre viklinger vil jeg serieforbinde til en variabel forsyning  

nr. 2 glemmer jeg indtil videre.

Hvis forsyningen skal levere mere end 1.5A himler regulatoren.
