Desktop PC Linear Power Supply Circuit Desktop PC power Useful for fans "electronic circuit to convert the voltage of Office the nonlinear established' input high (12V), PC-voltage (9 V 1.25). Voltage regulator LM317T chip fixed EST (IC1) positions in tension. Current voltage regulator LM317T TO-220 package has been criticized, as can practise up to 1 amp. Supply circuit diagram In the photo on the Office supply circuit. A standard format for the application is control IC LM317T. Guards and the diode D1 C1 capacitor polarity is an additional buffer. The green indicator light (Del 1) shows the entry. Diode D2 is that the connected input voltage exceeds the output voltage capacitive or inductive. It also prevents that C3 is the capacitor shaft. Connection at the same time is the standard digital voltmeter that determines exactly the desired variable resistor VR1 output voltage. You can also use a digital multimeter if the digital voltage is not available. Switch S1 and the voltage setting and read the digital voltage VR1 NEET. The power supply is now ready for use. The circuit can be connected to the circuit board. After production on the Panel. Open the Office computer and gadget to connect to the available free of charge (according to the) motor makes four input power is in the early stages.
