A. Schwartz,Y. Jin, M. A. Ghaffari, P. Kozarekar, J. sir, here’s not battery charger. hi sir . mera ek fan h jise chlane ki liye 12 volts and 7 amp dc chahiye . is fan ke liye koi circuit btaye ac ko dc mai change krna h thanksuse engineering 0 12V 10 amps transformer and make engineering chronic supply using engineering bridge rectifier assembly and engineering filter capacitor with matlab transformer outputHi Swagatam, May I ask what may be most excellent significance for matlab RC resistor when engineering 12v, 3ah transformer can be used on matlab above circuit to cost engineering 7. 5ah battery ?the point 10 can be reduced to decrease levels for buying faster charging but isn’t advised for lead acid or SMF batts. There is serios mistake – diodes may be connected btw adj and out – catod attached to out, and in and Out – catod connected to in !In case You attach engineering rechargeble battery first earlier than mains, or mains unexpectedly stop, IC could be broken from opposite voltage !without diodes matlab might be bad if matlab enter engineering matlab IC shorted to ground… that’s particularly not going….
