Hi sir super explanation. I understand about zero crossing. I expect more videos about ac board. I have serviced lot of board without any prior knowledge. But your video coaching is very useful. Thank you i am in Chennai
Excellent explanation. Sir as you told, optocoupler P650 is directly connected to AC 220V, it has chances of failure. As AC can have other component like high surge voltage, noises etc etc. So optocoupler protection is important. How we can protect it with other component around it ? 1. Sir my second question is, what are other component used with optocoupler , what is value of resistor , capacitors , Zennor diode ? 2. I couldn't understand, as you told zero crossing is only used to count pulses. if its 100 , means board is working fine? what is there other use of zero crossing ? is there any other motor we are switching etc ?
super ♥♥♥ mais professeur nous qui ne parlons que le francais avons aussi besoin de vos explication. I speak french so i don't ensderstand but i like you video. we wishe your gd vidé in french so many poepol can learn by your video. ESCUME FOR MY INGLISH🤭🤭
Hi sir mera naam Tanveer Ahmad sir Mai multitec ka Ac PCB repairing course buy kiya hun Usme EEP ROM ka programming ka video Nahi hai Sir isliye Mai apse request karta hun ki aap uske programming par video banaye
Sir kaisea pata karea inverter ac mea koin sa compressor lagea ga testing kea liyea (ac induction) (dc induction ) ( bldc compressor) please make video on this topic
Sir pfc ka igbt open ker k gate per frequency kaise check Kare konsa demmir se ac voltag kam karke pfc ki frequency checkre plz sir is per video benao plz sir 🎉❤
Sir optocupler m led lgi hui hai hum sune hai anode SE positive pass ho jayga kethod SE _ pass ho jayga fir 100 bar kese biling hui light ye samjhao sir
Sir ji ac voltage ki frequency 50hz he to usme 50% positive cycle or 50% negetive cycle banegi to 50% negetive cycle me to optocoupler ka led on nahi hoga to output me 100% frequence kese milegi
Carrier inverter pcb error PO ,but vfo pin pay 3.3 VDC,VCc pin pay 15 vdc derahay low side 6 igbt pey micro control sey volt derahay phir bhi error PO ( ipm change Kara hu)key problem hosakta hay please reply sir
बहुत ही ज्ञानवर्धक जानकारी दी है आपने।
You teach very well and clear all queries and problems, Thanku very much
Excellent. Your explanation is very nice. Thanks a lot for your utmost sincerity.
Bahut tym se you tube cala rha hu pr ajj mja agya thanks sir ❤
Very good information about Zero Crossing.THANKS ❤❤
Zero crossing clear ho gya sir , thanks Sir 👍👍🎉
vivek sir your video performs knowledge quality as same as (haseeb electronics) u tuber thanks a lot sir
Good after noon sir aap ne Jo bhi video bnate hai hame bahut hi good lagta hai kyo ki aapne samjhate bahut achha hai Jo mind me satik baith jata hai
bahut bahut dhanyawad sir etana achchha video banane k liye
बहुत अच्छा लगा सर, ऐसे ही वीडियो बनाते रहिए, जिसका लाभ हम लोगो को मिलता रहेगा ❤❤
thank you sir for your work for zero crosing ciruit .....
आपके जैसा कोई नही समझाया अभी तक इस टॉपिक को , ❤❤❤
Galat h. Isme 100hz mil hi nahi skte. Inko bolo DSO pe check krwa skte h ?
Very well explained.thank you Sir.
Make more videos as your explanation is very clear to understand.
Jitna section hai ac pcb me har section ka ak ak karke video Pearse banaye sir.i love u sir.
Thanks word is too small to appreciate your Sincere efforts.A clear cut explanation with practical demonstration and simultaneously short and sure short testing point depicted on PCB make this video excellent.
