Speaker Protection Board for High Power Audio Amplifiers ( Hindi ) ELECTRO INDIA

November 17, 2019 posted by


Today we will make speaker protection board When the transistors get worse then The voltage is reached at the speaker point high voltage can damage the speaker easily this board can help in this condition. it will cut the speaker point so let’s get started We got this made PCB from pcbway.com How we got that, we will see in the last segment of the video first we will make the board this color is matte green it will look like this in front of the simple green and these are the components we are going to use if you are making single sideboard. you must insert 1 jumper all resistors are 1/4 watts 1 pcs 1k resistors 1/4 watts 1 pcs 220k resistors 1/4 watts 1 pcs 47k resistors 1/4 watts 4 pcs 10k resistors 1/4 watts 4 pcs zener diode 4148 5 pcs diode 4007 1 pcs Transistor c9013 2 pcs Transistors c1815 1 pcs 220k Preset 1 pcs 47uf 25v Capacitor 2 pcs 220uf 25v Capacitors 1 pcs 470uf 25v Capacitor 1 pcs Voltage Regulator IC 7812 1 pcs LED 5 pcs 2 Pin 5mm Screw Connector 2 pcs 12 volt 30 Amp. Relay Now cutting Now soldering this is 12 volt 1 amp. transformer let’s attach it this is 200 watts audio board we have already created this 200 watts board in other video we are testing this board with 55-0-55 volt transformer but you should not use this transformer. you have to use the proper transformer for the board we have to work with caution while testing you can see the red wire in the back it is for + voltage and the grey wire is for speaker through the audio board connect it here and the speaker column wire connect here we have to be aware to the polarity lets power on let’s check the voltage as you can see here are the 80 volts and higher this is very dangerous for the speakers if we connect this wire directly to the speaker point of the audio board then it will damage the transistor but the speaker will survive with the help of this protection board let’s disconnect the speaker wire now we will connect the high + volt wire ok it’s working fine let’s check the speaker is it working or not it’s fine ok Now lets see how to get the PCB first of all Search pcbway click here login from here Then click here Then click here then enter designs then enter size then quantity then layers and material thickness and minimum space holes and color and check everything then calculate it then click here then upload the gerber file as zip it will pass after some time then click Proceed to checkout then you can mention your address here, we have already done here are the payment options confirm and pay and then we got this after one week If you like this video, hit the like button Dont forget to Subscribe Because we have a lot more to show Thanks for Watching this Video
