ronniefrown Posted October 28, 2009 Share Posted October 28, 2009 Unde as putea gasi un alimentator reglabil 9-18 V pentru o pedala ? Trebuie stabilizat sau nu ? Din ce am cautat, am gasit doar reglabil 9-12 V sau numai 12-24 V. Multumesc. Sunt din Bucuresti Link to comment Share on other sites More sharing options...
FiveseveN Posted October 28, 2009 Share Posted October 28, 2009 Se poate face usor cu LM317, un transformator cca. 220-15V si alte maruntisuri. Link to comment Share on other sites More sharing options...

Sunt din Bucuresti o pedala nu se alimenteaza doar cu o singura tensiune???? de ce-ti trebuie plaja de 9-18??? Link to comment Share on other sites More sharing options...
ronniefrown Posted October 28, 2009 Author Share Posted October 28, 2009 Pedala are un switch numit Headroom care dubleaza voltajul, inca nu am primit-o si nu am manualul, dar asta scrie pe site. Deja numai inteleg, pe alt site am gasit asta: Another important feature is the HEADROOM SWITCH. Set to the "HI" position, an internal electronic voltage doubler is activated – the Diablo runs on 18 Volts from a regular 9 V battery or power supply. The higher voltage gives more dynamic range, more headroom and tighter bass – just try it! Precizez ca sunt nul la electronica deci habar nu am ce inseamna !

FiveseveN Posted October 28, 2009 Share Posted October 28, 2009 (edited) Pai stai ca e total altceva. N-ai nevoie de alimentare speciala, isi scoate ea tensiunea care-i trebuie din 9V. PS: mi-a luat-o omu' inainte. Edited October 28, 2009 by FiveseveN Link to comment Share on other sites More sharing options...
ronniefrown Posted October 28, 2009 Author Share Posted October 28, 2009 Am inteles, multumesc ca m-ati luminat. O sa folosesc atunci o baterie. Link to comment Share on other sites More sharing options...
ronniefrown Posted October 28, 2009 Author Share Posted October 28, 2009 Conform charge pump circuit e nevoie de 18 Volts d.c. la intrarea pedalei iar cu un comutator trece intern pe 9 Volts.(amp/distortion sound) Electronic se poate realiza si functia inversa 9 - 18 Volts insa pedala inglobeaza principiul prim-enuntat, deci va trebuie o sursa 18V stabilizat care : -Vine cu pedala / -Se cumpara optional / -Il cumparati/construiti in tara sau... va face Heiko cadou unul... Deci sa inteleg ca am nevoie de un alimentator de 18V, iar pedala poate comuta pe 9 volti fara ca eu sa schimb tensiunea din alimentator ? Link to comment Share on other sites More sharing options...
ronniefrown Posted October 28, 2009 Author Share Posted October 28, 2009 I-am trimis un mail si tocmai mi-a raspuns: You don’t need a 18v power supply. If you run the pedal from a 9 volts power supply and switch to the "high headroom" (18 volts) mode, the voltage is doubled internally, even from a battery.
