Electronics Help Care Amplifier circuit diagram
This is a 1000-watt transistor circuit diagram using 2SC5200 and 2SA1943. This amplifier can make 1000 watts. We can use a 70-0-70 voltage, 15 amperes here. We know voltage X amperes=watts. 70X15=1050 watts. Here, use 10 pairs of transistors. This board includes speaker protection.
Details about 2SA1943
2sa1943 Polarity is PNP. The maximum collector power dissipation is 150 Watts. The maximum collector-base Voltage is 250 volts. Max Collector-Emitter Voltage is 250V. The Max Emitter-Base Voltage is 5V. The Maximum Collector Current is 17 amperes.
Details about 2SC5200
2sc5200 Polarity is NPN. The maximum collector power dissipation is 150 Watts. The maximum collector-base Voltage is 250 volts. Max Collector-Emitter Voltage is 250V. The Max Emitter-Base Voltage is 5V. The Maximum Collector Current is 17 amperes.
Amplifier watts depend on the voltage and amperes. For this, we have to use a strong voltage and amperes to get a strong output watts. The transformer should be of good quality. The best diode and the capacitor required to make a good output watts.
A diode and a capacitor:
Here is the diagram for using diodes and capacitors. This circuit is for making an amplifier voltage. Making an amplifier requires a DC voltage. Here we use a transformer to make an AC 220 to 50-0-50 voltage. This transformer is a step-down transformer. Here used a diode is used here to convert an AC voltage to a DC voltage. and using capacitors to store the voltage. The capacitor stores the voltage and helps to make a DC voltage.
This is the stk 4191 amplifier circuit diagram stk401-110. here used stk 401-110 ic. This is 70+70 watts amplifier. So 70+70=140 Watts amplifier. For getting 140 watts, we have to use 150 watts transformer. If we use 25-0-25 volt so 25+25=50 volts. We know voltage X ampere= Watts. So, 50X3=150 Watts. For 50 volts, we have to use 3 amperes. Or if we use 30-0-30 volts. Then 30+30=60 voltage. So 60X2.5= 150 Watts.
