This transistor is used for switching as well as amplifier applications. The 2N3055 transistor is a general-purpose NPN Power transistor built with a sealed metal case. 2 power Transistor 2N3055 is used in this circuit to. Use the 5k potentiometer for the adjustment of voltage and the 10k potentiometer with BD139 transistor for adjustment of current. This device can also be used as a programmable output regulator, or by connecting a fixed resistor between the adjustment and output, the LM317 can be used as a precision current regulator. This is the circuit diagram of the voltage and current regulator circuit that can give the output of min 1.5v to max of 30v DC and current min 0 to max 10A. Overload protection remains functional even if the ADJUST terminal is disconnected. It has current limiting, thermal overload protection, and safe operating area protection. Here Resistors R1 and R5 set the output to any desired voltage over the adjustment range 1.2v to 37v. To set the output voltage it requires only two external resistors. This LM317 regulator IC capable of supplying more than 1.5 A over an output-voltage range of 1.25 V to 37 V. The LM317T is an adjustable three-terminal positive-voltage regulator. send catalauge or price PCB of 60W RMS OTL integrated audio amplifier circuit full detail. Get convenient in building with Have a good time. This is a 36V to 50V Power supply circuit for 35 Watts to 50 watts amplifier circuit. Fix the circuit in a cabinet and both potentiometer knob connected with the circuit should out of the cabinet for adjustment. PCB layout of 35 watts to 45 watts amplifier using 2N3055 transistor. The rectifier module IC is a readymade Bridge Rectifier.īridge rectifier ic module is available in the market of 15A or different current rating, you can use this rectifier module. The output of the transformer will provide about 24v Ac. connect the AC pins of the rectifier diode module with both side wires of the transformer of 12-0-12. A transformer of 2 A will not give more than 2A current. If you required 10A the use a 10A center taped transformer of 12-0-12v.Then output current depends on the current rating of the transformer. If you need a maximum of 5A current at output then use the 5A transformer.
