I found 2 power supply diagrams when mixing my archive. well-prepared, especially for beginners in electronics, easy-to-understand instructions, simple descriptions of circuits, layout drawings. Adjusted symmetrical power supply by HAYDAR AKIN ANADOLU VOCATIONAL HIGH SCHOOL Single-output Adjustable power supply prepared by AVCILAR ANADOLU TECHNICAL and INDUSTRIAL VOCATIONAL HIGH SCHOOL 2 of the documents used in the education of the students I think. Thanks to the people who prepared it.

MPS-0241 ADJUSTABLE POWER SUPPLY

his kit is an easy-to-set adjustable power supply module. It is ideal for powering applications that require a variety of DC currents up to 650 mA.

Features

1-Circuit is onboard and everything is very easy to install.

2-V / A scalasy is added to our device. You can monitor current and voltage.

3-If the output (output) is short, it is circuit protected and there is no fuse at the entrance.

Circuit Description

The base of our circuit (1.2V-37V) and Imax = 1500ma with TO220 in the case of the 3-legged LM337 is integrated. The desired value is reached with the potentiometer. D1-4 diodes A bridge that converts AC voltage to DC and a rectifier rectifier. Since the transformer is 2x13VAC, a relay is installed in order to get maximum efficiency from both the transformer and the overload on the LM337 integrated circuit. It operates as a bridge rectifier. C1 is a filter capacitor and extinguishes parasites with C2 and C3. The diode diode
is inverted polarization version in normal operation.

If the output is connected to a voltage at the same polarity (battery, battery, etc.) the regulator can protect the D5 diode when a reverse polarity voltage is connected to the output and inductive (emf) loads the integrated circuit. The regulator outputs a nominal 1.25V reference voltage between the discharge and adjustment ports. this is applied over a constant voltage R1 and causes a constant current to flow.

This constant current changes to the potentiometer and the voltage on it changes to the potentiometer and the output voltage is adjusted as a result. The output voltage is calculated with V out = 1.25 (1 + Rp / R1). The current on the led should be between 5 and 20mA and the R5 resistor is set with the resistor R5 depending on the required voltage. R5 = (Vout-Vled) /10.10). VLED = 2V (approx)

This kit is an easy-to-install symmetric adjustable power supply module. It is ideal for feeding opamped applications that require DC current at the 0 × 0-500mA levels.

The base of our circuit (1.2V-37V) with Imax = 1500mA TO220 in the case of 3-legged LM337 negative and LM317 positively adjustable integrated. The output voltage is determined according to the choice of R1 / R2 and potentiometer between 0 – (+/-) 12V. The desired value is reached by the potentiometer. Diodes D1-4 form a bridge and a parallel rectifier that converts AC voltage to DC. It is a C1 / C2 filter capacitor and extinguishes parasites with C3 and C4. The D5 / D6 diode is inverted polarization version in normal operation.

If the output is connected to a voltage at the same polarity (battery, battery, etc.) the regulator can be protected D7 / D8 diode is connected to the output of a reverse polarity and protects the integrated circuit in inductive (emf) loads. The minimum output voltage of both integrators is due to the internal voltage reference value 1, Two 1N4148 diodes are used to reduce the lower value of this voltage to 0V. In other words, 1 1.4V zener can be used instead of two diodes. Thanks to the diodes, the output voltage can be set between 0 – (+/-) 12V. When these diodes are not used (short circuit), the output voltage is between +/- 1.2V-12V.
