Sursa laborator!

[Tita]

Salut!

Acuma ceva vremi mi-am terminat de construit sursa mea de laborator!

Carcasa este de la un stabilizator de tensiune 220V c.a..care era stricat(vecinu la lasat in ploaie )..asa ca am adaptato cat de cat pentru a arata cu o sursa..Ex

Unde era priza de iesire am pus voltmetrul;

Deasupra voltmetrului era becul de indicare...am pus un potetiometru..si unul sub acesta(fin-brut);

Deasupre intrerupatorului de retea era siguranta;

Pentru a putea pune mufa de retea am incercat sa tai cat mai atent gaura ...

Restul este gaurit de mine....

Este drept ca sursa este destul de mare in dimensiuni...(dar ce puteam face...sa tai carcasa in doua? )

Uite schema :

Astept parerile voastre despre produsul" final!

[Dr.L]

Felicitari, frumos realizata! Nu i-ar sta mai bine la 'proiecte complete' ?Ce specificatii are?

[Tita]

ups..se poate muta unde trebuie topicul...sczPai pe tensiunea variabila 1.25V-13V 5A maxim si cea cu comutator rotatiV(4 pozitii) si transformator cu priza mediana ....tensiune +/masa/- 3V,5V,9V,12V max 1A.Mai incolo voi incerca sa adaug si o protectie la scurt cu tranzistori sau relee(am loc )

Bun, si frumos lucrat in interior, asa cum cineva zicea, e placut sa vezi ca inca se mestereste, sincere felicitari, imi place ce vad.

 

PS: LM-urile sunt foarte bine protejate intern deci nu mai este nevoie sa adaugi ceva in plus. carcasa nu e deloc prea mare, de ce n-am avut si eu una la fel... ce happy as fi fost

[Tita]

Mersi Acesta a fost primul proiect serios pe care l-am finalizat cu success! Deja lucrez la un alt proiect:Un aparat analogic care sa masoare: frecventa1-100Hz si 1-1KHz,rezistenta interna a condensatoarelor ,capacitatea condensatoarelor de 1pF pana la 1uF si inductanta 0-100uH...pe baza IC NE555 si 74HC14
