Have you at any point gone over power issue where when you switch on the force supply and the circuit blow? You have genuinely looked at all the parts in the force (essential) and optional area and every one of the parts is by all accounts alright! Where is the flaw? A breaker passed up a shorted connect rectifier, deficient posistor, power semiconductor or FET, shorted essential twisting of switch mode power transformer, shorted auxiliary diode and so forth Be that as it may, in this article I’m gone to show you one more confidential of electronic investigating tips.

I got disappointed with respect to where is the reason for power issue. Each time when I switch on the force supply the breaker blow promptly (the wire became dull shading and this show that there is a significant short out in the force supply). I have checked every one of the parts in the force supply and can’t discover the offender! What I do is I desoldered every one of the presumed parts individually and supplanted with a known decent part. I at last found the caused of the force supply issue. Prepare to have your mind blown. It was the principle channel capacitor (220 microfarad 400 volt). In the wake of supplanting the channel cap the force supply turned out totally great. I start my investigator work to discover why this capacitor can made the wire blow despite the fact that I previously affirmed it OK with my meters. Visit for more details

The meters that I used to check the channel cap were simple meter, advanced capacitance meter and esr meter. In this article I won’t disclose concerning how to check capacitor or testing capacitor and how capacitor work. I accepted the greater part of you realize how to genuinely take a look at capacitors and furthermore by and large utilizing this kind of meters. Estimated with simple it showed capacitor charging and release, with computerized capacitor analyzer it displayed around 220 microfarad and with esr meter it showed low esr perusing!

This demonstrated that the terrible capacitor breakdown when under full working voltage. Then, at that point, how would I affirm that this channel capacitor is flawed? By utilizing a simple protection analyzer. At the point when I interface the broken cap to the meter and press the go catch it showed an extremely low opposition and this is the demonstrated of short out between the plate when voltage applied! There isn’t anything to do with terrible electrolyte. A decent capacitor will just showed a charge and release in the protection meter very much like you are checking a capacitor utilizing simple multimeter. In the market there is a lot of reaches that you can purchase. It has the scope of 50v, 100v, 250v, 500v, 1000v and surprisingly 5000v! Assuming you need to test a capacitor of 100 microfarad 160v then you need to choose 100v. On the off chance that you select 250v, it will blow your capacitor that is under test.
