Sir mera computer ka 3no SMPS kharap hoya hai 3no SMPS jab kharap hoti hai aki folt hoti hai harbar MOSPHD S20C45C A DIODE Shot hoti hai
Intex techno smps mai 12 v ke saath kitne ampere supply karta hai
रेटिग तो काफि लिखी हुई होती है, लेकिन उससे उतनी पावर नहीं ले सकते | वैसे 12 वॉल्ट की लाईन में 2 से 3 एम्पीयर अधिकतम ले सकते हैं। कम्प्यूटर की पॉवर सप्लाई में 1 ही लाईन में ज्यादा पावर नहीं ले सकते। अगर लेते है तो SMPS बन्द हो जायेगी।
Sir mere pass same power supply hai usme dono power transistor short the bo nikal kar power dene per standby voltage 12v dikha rha hai kya problume ho sakti hai please reply karo
Atx SMPS mein 2 auxiliary power supply hoti hai ek supply mein 5 voltage aaega Jo PS on ka kam karti hai dusri supply mein 12 volt se 24 volt Tak ho sakta hai 5 vote ki supply mein agar 12 voltage aata hai supply mein aap feedback section ko dekhiae vahan per kharabi ho sakti hai
Sir, मेरे smps का mosfet खराब हो गया है, ita13n50r mosfet के बदले कोसा मॉस्फेट use करसकता हु? क्या मैं ita13n50r के बजाय 13007t mosfet का उपयोग कर सकता हूँ?
आप MOSFET की जगह पर 13007 ट्रांजिस्टर नहीं लगा सकते आप मॉसफेट की जगह पर मॉसफेट ही लगाये 13n50 की जगह k2611 या 22n50 मॉसफेट लगा सकते हो SMPS सही काम करेगी
13005 b lga skte h kya
Yes
13007 mosfat ok. But standby suply mosfat short konsa mosfat lagana chahiye
13007 yah trangister hi hota hai MOSFET nahin
Is SMPS mein Standby supply ke liye trangister c5027 laga hua hai
Iski jagah per 2sc3457 ya c3457 laga sakte hain
Aur dusre type ki SMPS meinStandby supply ke liye Kai SMPS mein mosfe bhi laga hua hota hai mosfet ka number 2n60 and 4n60
Thanks
Resp Sir! Dell 6Pin SMPS Main Filter Capacitor 340V OK, All FETS are all OK but not SB out Where the Problem Sir. Please Advise Sir. -- ChinnaRao Paderu Andhrapradesh
There is a separate circuit for standby supply in SMPS. A small SMPS transformer is installed in it. It has two supply outputs on which 5 volt supply and 12 volt or 18 volt supply can be provided. Diode in the output of standby supply. And test the capacitor thoroughly. For switching the standby supply transformer, IC can be used or Mosfet or even transistor. In the switching area of the stand by transformer, you test the supply or there may be some resistance. may get spoiled
can i help you further thanks
Computer SMPS using KA7500B pwm single ic Fan spins for seconds and stops. Standby 5v ok, at ic pin no4 3.4volts available, after ps command, it shows 4.35volts instead of 0 volts and ps not on means no output voltages. Please give the solution.
In SMPS, connect PS on and ground wire together and SMPS turns on.
If SMPS does not turn on by doing this, then there may be a fault in PWM IC or voltage feedback IC in SMPS. Test the diode and capacitor in the output of SMPS thoroughly. If SMPS output voltage comes out on pin number 4 of KA7500, then there will be zero voltage on pin number 4. If there is no output voltage in SMPS, then there can be 2.5 volts to 5 volts on pin number 4.
When SMPS is without load, give power to SMPS with the help of 60 watt series lamp. Give ground voltage on pin number 4 of 7500. SMPS will turn on at output but voltage may be wrong.
If SMPS does not turn on by doing this, then you can see the fault in the feedback area.
Or SMPS does not turn on, test transistor and PWM IC in the driver area high voltage side of SMPS.
Thanks. Have a nice day.
Even if standby 5v is ok, there a bit problem in smps. The smps will turn on with smps tester, all voltages will be ok, But once connected to the motherboard, the standby 5v keeps fluctuating 4v to 5v and this will not turn on the motherboard, (Motherboard is ok tested with other smps) ,i attempted to repair but couldn't find out faulty components , all components were testing ok, near standby section.
If possible pls try to upload video on this type of problem.
You have a fluctuation of standby voltage in SMPS. There is a capacitor installed in the 5 volt line. Test it and try replacing it with another capacitor and you can also increase the micro-Farad of the capacitor.
And there is a Schottky diode installed in the 5 volt line, you can replace it and see if you do this then the SMPS can be fine
thanks
AP na 13007 do transistor change Kiya hai or tisra Bala transistor ka kaya no hai
Or uski kaisa chak Kara
Is SMPS mein teesra c5027 trangister ha Jaise pahle aur dusre trangister ko check karte hain usi prakar teesre trangister ko bhi check karte Hain
Sir i have a 450watt frontech smps, when turing on, no sound ,no output ,no standby output ,
13007 trassistors are ok but standby supply mosfet sorted
SMPS will not turn on unless there is voltage in the standby supply in the SMPS, fix the standby supply,
@@totalcircuit yes but i cannot find what is damaged in the standby supply circuit
@@totalcircuitsir i have power supply, i repaired the 5volt standby but no output still, there is a very high pitch sound coming from the transformers what can go wrong?
Mere smps me d4242 411c laga huva ve iskijagha konsa trjestar lagao pleg sar
D4242 transistor ki jagah per
3DD4204D ya 3DD4205D laga do working Karega
Thanks sar
Sir kea ham power supply ko without box use kar sakty hain,,,
आप पावर सप्लाई को बॉक्स के बिना यूज नहीं कर सकते क्योंकि बॉक्स में फेन लगा हुआ होता है जोकि पावर सप्लाई को ठंडा करने का काम करता है बिना फेन के पावर सप्लाई खराब हो सकती है
You cannot use the power supply without the box because there is a fan in the box, which works to cool the power supply, without the fan, the power supply can be damaged.
@@totalcircuit sir mujh hindi nhe ati
Very high pitch sound coming from SMPS
No 5 volt standby output
Help
If the standby supply does not come in the Atx power supply of the computer, then the power supply will not turn on and there will be no sound.
Still if there is sound then test the capacitor in the input section and test the diode and capacitor in front of the transformer that makes the supply in the stand and sometimes there is a sound of cut cut when the stand by supply is short circuit.

Mere wale pe secondary section me tino transistor kharab hogaye he but mujhe wo number ke transistor mil nahi rahe he to app koi solution bataiye jisse me smps ko thik kar pao 🥰🥰🥰
अगर आपकी smps इसी टाइप की smps है। तो आप सेकेंडरी साइड में दो ट्रांजिस्टर लगते हैं उनके नंबर 13007 और 13009 नंबर के ट्रांजिस्टर लगा सकते हो और स्टैंडबाई सप्लाई बनाने के लिए ट्रांजिस्टर का भी उपयोग होता है और MOSFET उपयोग होता है

Diode ko hitsink per tight karo SMPS mein fen sahi hona chahie diode lagate samay hitsink compound ka jarur prayog Karen diode ki qualities Sahi nahin hone per bhi kharab hoti hai 2045 diode ki jagah MBR3060PT laga do kharab nahin hogi
