Simple Power Supply with LM337 and LM317
Stirring repository 2 drawings, details, etc. I found one power supply scheme. well prepared, especially for beginners, easy to understand electronics simple instructions to, layout drawings are explanations about circuits.. Regulated by the symmetrical power supply HAYDAR AKIN Anatolian Vocational High School TURKEY HUNTERS Single Output regulated power supply made by the Technical and Industrial Vocational High School students to guess the documentation used in education 2 one.. I mentioned earlier, especially designed smart single source supply “bypass” method is used – Thanks to people who contributed to preparing.
MPS-0241 ADJUSTABLE POWER SUPPLY
Power that this kit is easy to set yapylabilir Hazyrlamş kaynağy modülüdür.1500 mA to power up is ideal for applications that require various levels, DC akym.
Features
1-Everything our circuit on the PCB (onboard) is,is considerably simplified assembly.
2-Cihazımıza V / A and the voltage can skalasy additional edilmiştir.Akım.
3-Exit (output) engage in the protected circuit and the insurance konmuğtur kysa.
Circuit Description
The foundation of our circuit (1.2V-37V) In the case of TO220 with Imax = 1500mA 3 voltage between 1.2V-30V LM337-legged and potnsiyometrenin entegredir.Çıkış is determined depending on the choice. Reached the desired value with potentiometer. Diodes D1-4 AC voltage to DC transformer 2x13VAC oluğturur dönüğtüren is a bridge rectifier and parallel to get maximum efficiency from both the transformer and the load so that there are more than shards LM337 integrated circuit as a relay çalşan konmuştur.Röle inlet 12V 12V diagnosed until after the parallel rectifier
versiyonludur diode polarity inverted normal çalşmada.
Output a voltage in the same polarity bağlanyorsa (GDP,battery…as) outputs a voltage regulator with reverse polarity protection diode D5 is connected to the utility and the inductive (emf) integrated circuit protects the load. The regulator nominal 1.25V reference voltage çıykış by risks and setting the connection produces noktalary. R1 is a constant voltage is applied and fixed on this causes a akymyn akmasyna.
This constant current flows through the potentiometer to the change of the pot and as a result will vary with the voltage on the output voltage is set to its. Çıkış voltajı V out = 1.25(1+Rp/R1) with the calculated.(Rp potans değeri)LED output voltage indicates that the. Led on the akym 5 and resistor R5 is adjusted to be between 20 mA and R5direnci needed depends on çykş voltajyna. R5=(Vout- Vled)/10.10 ) Calculated with the formula. Vled = 2V(about)
SYMMETRIC MPS-2X0-12V ADJUSTABLE POWER SUPPLY
Designing the power supply that we set this kit is the easiest yapylabilir modülüdür.2 symmetric×0-500opamplı ideal for applications requiring DC voltage levels to feed mA.
The foundation of our circuit (1.2V-37V) In the case of TO220 with Imax = 1500mA 3 LM337 bacaklı negatifve LM317 Positive adjustable integrated. The output voltage 0-(+/-)12Depending on the choice of V is determined by risks R1/R2 and potentiometer. Reached the desired value with potentiometer. Diodes D1-4 AC voltage to DC rectifier converts creates a bridge and parallel . Extinguished with the noise filter capacitor C4 is C1/C2 C3ve. Versiyonludur normal çalşmada reverse polarity diode D5/D6 çevrilmiğş.
Output voltage is connected to a polarity (GDP,battery…as) outputs a voltage regulator with reverse polarity protection diode D7/D8 bağlanyrsa benefits and inductive (emf) minimum output voltage of the integrated circuit chip loads korur.her two, Due to the internal voltage reference value of 1.2 V voltage lower value civaryndadır.Bu çykş 1N4148 diode syfır two units were used to inflict the level of 0V. Alternatively, the two pieces instead of a diode 1 luk x 1.4V zener is available. Voltage through diodes çykş 0-(+/-)12V can be adjusted by risks. When this diode kullanılmadğı s (kysa devre) made the output voltage /-12V is between -1.2 V.

At first glance, but I have looked at more than two errors in the diagram. The first ‘Bobin’ parts which are described in. Resistance coil is not necessary that the part, yani sont direnci. In fact, what article V / A meter scale are indicated for the so-called shunt resistance possible to calculate what would happen, but by the value of the measuring instrument.
The second is the key link to the wrong selection of current and voltage measurement. But the voltage is the only issue is the current measure current mannequin stands as a dysfunctional. O to make the correct function key and the outer ends of the measuring instrument in the middle ucununn one side to the end of the coil entegrei (for the current) post as a variable resistor on the other side trim (to the voltage) must be connected to.
