Bonjour,

Je vais me faire un transfo d'isolement.

( le schema de sonelec-music, je remplace le relais par un semi conducteur)
, et je voulais savoir comment calculer l'amperage maximum ?
Je pars sur une base de  transfo de micro-onde, et je bobine en 2,5 mm2 !

On ne met JAMAIS un semiconducteur, encore moins un triac, dans un  


court-circuit

3mm pour une coupure simple. Je te laisse le soin de rechercher la mise

Re: transformateur et labo du fou ?
Slt,

Et avant toute chose ma passion s'oriente vers le calcul du VA du transfo !

Merci
