kiske13 Posted November 16, 2019 Share Posted November 16, 2019 Salut. Am gasit pedala Framus din imagine ca fiind ok pentru amlifuri ENGL. Intrebarea mea se refera la montajul unor leduri la pedale. Ampliful da 10mA pentru led. Ce parametrii trebuie sa aiba ledul de 5mm, cati lucsi sa nu fie prea slab sau prea tare si ce amperaj (am gasit de 20mA)? Montajul se face simplu, inseriand cu intrerupatorul? Multumesc frumos. Link to comment Share on other sites More sharing options...
vldmlt Posted November 18, 2019 Share Posted November 18, 2019 exista vreo schema, ceva? Link to comment Share on other sites More sharing options...

vektor Posted November 18, 2019 Share Posted November 18, 2019 Par sa fie butoane independente @vldmlt Link to comment Share on other sites More sharing options...

Nu am dat click pe imagine ca sa o vad in intregime.@kiske13 , in cazul asta,cred ca trebuie sa masori si ce tensiune ai pe mufele de footswitch din amp, in vederea dimensionarii rezistorului pentru limitarea curentului prin LED.

kiske13 Posted November 21, 2019 Author Share Posted November 21, 2019 Din pacate despre tensiune nu da info engl. Doar curent de 10mA este specificat. Link to comment Share on other sites More sharing options...
vektor Posted November 21, 2019 Share Posted November 21, 2019 Man sunt led-uri, ori 3.5 ori 5v da. La 10mA 5V doar led rosu functioneaza corect. Not rocket science Link to comment Share on other sites More sharing options...
kiske13 Posted November 21, 2019 Author Share Posted November 21, 2019 Eu aveam nevoie de ce intensitate ar fi ok si daca se leaga simplu in serie cu switch-ul!? Nu e fizica atomica, dar m-am gandit ca imi raspunde un coleg, care le are cu electonica, sa nu fac balarii. Sorry for this topic. Link to comment Share on other sites More sharing options...

Liviu.Pop Posted October 2, 2021 Share Posted October 2, 2021 Daca n-ai rezolvat încă, înseriază la LED un rezistor de 1k și dacă e prea slabă lumina mai tatonează niște valori. Dar la pedale nu tre' să fie "halogen". 1 Link to comment Share on other sites More sharing options...
