It is possible to also work with your digital multimeter in case the digital voltmeter isn’t around. Refer refer to the following picture for the pin configuration of LM317, just before soldering it on the PCB. No Matter you're replacing a defective or lost power supply or simply purchasing one to go with a product that needs power, Full range input, Single output) Wall Mount Adapter PleaseNote Original Does not require separate AC power Cord for USA & Canada only. An adjustable three-pin voltage regulator chip LM317T (IC1) is applied right here to deliver the desired voltages. Switch on S1 and set the needed voltage through potensiometer VR1 and start reading it on the digital voltmeter.
Careful circuit design has resulted in outstanding load and line regulation comparable to many commercial power supplies. The LM317T regulator, in TO-220 pack, could deal with current of approximately 1 ampere in reality.
Diode D2 keeps the output voltage from increasing above the input voltage when a capacitive or inductive load is hooked up at the output. LM338 only one, Similar to the LM317 IC number, but it can supply up to 5A, as the circuit shown in Fig. By the voltage output value obtained from the IC depends on the voltage value at the Adj pin of IC1, or can be varied by adjusting the VR1.

Then, the wiring for circuit wiring and various components can view of the example in Figure 3.
What to look out carefully for is the polarity of the electrolytic capacitors and Diodes correctly. Italo Morello October 16, 2013 Ill try this circuit to heat my model airplane engine?s glow plug. However, since I will use 12 VDC battery instead of AC,I imagine don?t need neither big capacitance filter condenser nor the 1N4007.Will experiment, anyway Thanks a lot and will let you know if I could fly or remained grounded. Suresh de Fonseka August 28, 2014 please send me the correct cct diagram early chayapon August 28, 2014 Hi, ivanThanks for your feedback,.
John Sabalboro September 19, 2014 Sir, its John from the Philippines, What if I want to add 12v and 15v output? If it is the more common break before make, then as you change the voltage selector from one setting to the next there is a brief moment when it is open circuit.
I destroyed a low voltage circuit on my unit ( maximum voltage 18v) switching from 3 to 4.5v You might need to shop around to find a make before break type.
