zahvaljuci Crnom ( crni.ri,nije bas aktivan na forumu ) napokon sam dobio jedna strujna klijesta na koristenje,pa smo se malo igrali :D

shematski prikaz :lol: gdje vidite i osobe koje su bile prisutne na testiranju :D
Image

pojacala koja smo kurili...ovaj...testirali:
Image
PowerAmperi PA60,PA150,Q250,Rockford Fosgate Punch 25.2 i 250a2,Lanzar Vibe430,Steg QM75.4.bili bi i Alienovi DLSi,ali ih nije dao :D drugi put :)

Izvor signala - ton generator - 50 Hz,osciloskopom se namjesta maximalni naponski izlaz pojacala ( do klipa ),napajanje je bilo uglavnom 12 V pod opterecenjem,Vesna 75Ah i punjac od 11 A,voltmetar i strujna klijesta mjere Vrms i Irms,to dvoje pomnozeno daju rms snagu.opterecenje je bio otpornik 4.6 Ohma,200 W.

rezultati:

[pojacalo] 1kanal - [Vrms][Irms][Prms][deklarirano] bridge - [Vrms][Irms][Prms][deklarirano] [ucinkovitost]
PA150 17.5V 3.6A 63W 75W 27.0V 5.5A 143W 300W 60%
75.4 17V 3.75A 65W 75W 31V 6.75A 209W 250W ??
250a2 16.5V 3.65A 60W 62.5W 32V 7.13A 228W 250W 61%
PA60 12V 2.56A 30W 30W 19.5V 4.2A 81.9W 100W ??
Q250 13V 2.85A 37W 50W 21V 4.5A 95W 100W 41%
25.2 13V 2.85A 37W 25W 22V 4.78A 105W ?? 53%
430 16V 3.35A 53W 125W 25V 5.38A 134W 400W 50%

Steg je pokazao moc reguliranog napajanja,PA150 je zesce zakazao u bridgeu,ali pojacalo je popravljano pa mu oprastam,a i deklarirano je na 1 ohm po kanalu,a toliko ga nismo spustali,Lanzar je takodjer poprilicno zakazao,a nije popravljano,a mali Rocky se zato iskazao i pokazao pravi stari RF duh i izgurao prakticki 50% vise snage :D

Evo maloprije završili s testiranjem pojačalo kod killa mislim da je ovo prvi pravi test ty mjerenje snage tu na forumu , nadam se da čemo uspjeti u sljedečih nekoliko dana dobiti još par pojačal na stol čisto da da se zna koliko šta snage daje , na sljedečem mjerenju nadam se da ču uspjeti nabaviti od frenda otpornik s točno 4 oma jer ovaj je bio 4,6 oma i da čemo srediti neko stabilno napajanje jer tako da možemo svaki put osigurati iste uvjete.Ajmo sad i par slikica :
Ekipa s mjerenja

Moja beba steg 75.4 malo sam ga otvorio prije mjerenja
