Amplifier circuit 1200 watts:
This is an amplifier circuit that produces 1200 watts. Here, we used 2sc5200 and 2sa1943 transistors. One pair of transistors can make a maximum of 150 watts, so we used six pairs of transistors. It’s a mono diagram. For stereo, we need a dual board. We are using 60-0-60 voltage and 10 amperes. One transistor can take 1.2 amperes.
We have to use a good voltage and amperes to get a good output of watts. because we know that Voltage X amperes = Watts.
2sc5200 Polarity is NPN. 2sa1943 polarity is PNP. Max Collector Power Dissipation is 150 Watts. The maximum collector-base Voltage is 250 volts. Max Collector-Emitter Voltage is 250 Voltage. The Max Emitter-Base Voltage is 5 Voltage. The Maximum Collector Current is 17 amperes.
This is the Speaker protection circuit diagram. It can protect our Speaker from the burn. If the amplifier has any problems, this circuit can save our soundbox. Normally, when the transistor makes a short circuit, the voltage comes out from the speaker output line, and this circuit protects that voltage. This circuit should not allow direct voltage to be sent to the speaker. This circuit is essential for protecting the speaker.
