— | The XL4005 converter is designed to lower the output voltage value. The main advantages of this module are: small size of the board, does not require bulky heatsinks and has a high efficiency. The module can be used to power circuits with a large voltage drop, charge batteries, design a laboratory power supply, etc. The module is an improved analogue of the LM2596S buck converter. The buck converter module is designed based on the XL4005E chip. The microcircuit has 5 pins and is made in the TO-263 package. The input voltage range of the microcircuit is from 5 to 32 V, and the output voltage is adjustable in the range from 0.8 to 30 V. You can adjust the output voltage using a trimmer resistor. The output current range is from 0 to 5A. When supplying the load with an operating current of more than 3.5A, it is necessary to install a heatsink. A place is provided for the installation of a cooling device on the back of the module chamber. The module board has 4 outputs: IN+: input voltage IN-: common wire ("ground") of the power supply OUT+: output voltage OUT-: common wire ("ground") of the device The XL4005E chip has built-in protection against overheating (activated when the temperature reaches 125 ° C) and against short circuit (short circuit).

— | The triac power controller is designed to regulate the rotational speed (revs) and ensure optimal operating modes for sewing and kitchen machines, hand-held portable tools, where an alternating current collector motor is used as an actuating element, electric heating and lighting devices, soldering iron power, asynchronous AC motors. Suitable as a budget regulator for most power tools (grinders, drills, rotary hammers, planers, etc.). The radiator practically does not heat up at low powers up to 800-1000 watts, depending on the nature of the load. With a load of more than 1 kW, it is recommended to increase the radiator area or add forced cooling. For example, in vacuum cleaners when repairing failed "native" regulators, it would be a good decision to install the regulator so that air flows through it. It should also be noted that the maximum output power of a device that is connected to a regulator of this kind will drop by 4-5%. This is due to the fact that the opening of the triac occurs approximately at the moment when the sinusoid is in the amplitude of 90-100 volts. The principle of power control is to change the moment of switching on the triac after the transition of the sinusoid through zero. The more time the triac is in the open state, the more power is supplied to the load. Since the triac turns off at the moment when the current flowing through the triac becomes close to zero, then we will set the duration of the triac opening within half the period. At the beginning of the positive half-cycle, the triac is closed. As the mains voltage increases, the capacitor charges through the resistor. The charge of the capacitor continues until the voltage across it reaches the breakdown voltage of the dinistor of about 30 volts. The dinistor will close the circuit and open the triac. The triac remains open until the end of the half cycle. The variable resistor sets the charging time of the capacitor, and, accordingly, the moment of opening the dinistor and triac. This is the basis for the ability to adjust the power. During the negative half-wave, the principle of operation is similar. • Input voltage: 90 ... 250 V • Maximum power: 2000 W • Maximum output current: 9A • Size: 48 x 54 x 27 mm. | 43 | DIP | 1 PC. | |||

The module can be used as a driver of powerful LEDs, a battery charger with a large capacity, etc. The output voltage is adjusted using a trimmer resistor. To debug the required value of the output voltage, you must connect a multimeter to the terminals of the converter and adjust the output voltage by smoothly switching the potentiometer.

— | The NE555 module is a square wave generator. This module can be used to test low and high frequency circuits, amplifiers, radios and other devices. It can also be used to control the parameters of the output pulses over a wide range. The module is assembled on the basis of an analog integrated circuit NE555. The NE555 chip is a timer that generates pulses with stable characteristics over time. It consists of 2 diodes, 23 transistors and 16 resistors. The output current of the microcircuit is 200 mA.

— | The photo relay module activates the relay at a certain light intensity. The photoresistor, which is connected with a cable 20 cm long, determines the level of illumination. When light hits the photoresistor, it changes its resistance. Because of this, the voltage in the circuit changes, which signals the amount of light. The module can be used in projects that require the relay to be triggered in the presence of a given light brightness (street lighting, turning on car headlights, etc.). The board has an LM393 comparator that determines the light intensity across the photoresistor. The sensitivity level of the sensor can be adjusted using a trimmer resistor. The module does not have on and off timers. The relay is activated when the specified sensor sensitivity threshold is exceeded. If the illumination often changes its state, then the relay will operate frequently. The photoresistor is connected to the module using the COS pin. There are 2 terminal blocks on the module board: J1 (terminal 1): relay power is connected J2 (terminal 2): load connected There are also 2 LEDs on the board: D1: signals the power supply of the module D2: lights up when the specified sensor sensitivity threshold is exceeded You can supply power to the module board from an external power source. The module supply voltage is 5 V. The relay board switches voltage up to 250 V and withstands current up to 10 A.
