— | This module is a high power and reliable DC voltage converter that is designed to regulate the output voltage. Thanks to its good parameters, the voltage converter can be used in various fields. The module can be used as a power source for various LEDs, charging various portable devices, etc. The output voltage is adjusted using a trimmer resistor. The variable resistor must be calibrated before connecting the instrument to the DC voltage converter. The microcircuit already has an installed heatsink. The maximum power of the voltage converter is 120W. If the output power of the module exceeds 80 W, then the existing heatsink must be replaced with a more powerful additional cooling. The maximum output current is 5 A, the efficiency (coefficient of performance) of the converter is up to 90%. At an ambient temperature of 40 °C, it is recommended to install additional cooling for the inverter. The module is not protected against short circuit (short circuit) and reverse polarity. An external power source and the device are connected to the voltage converter using screw terminal blocks. Terminal designations: IN+: input voltage 10-32V IN-: "ground" OUT+: output voltage 35 - 60 V OUT-: device common wire Powered by an unregulated external power supply. The DC input voltage range of the converter is from 10 to 32 V, and the output voltage range is from 35 to 60 V. The red LED, which is connected to the power buses, indicates power supply to the module.

— | This module is a powerful and reliable DC voltage converter. The converter changes the DC output voltage in the range from 60 to 97 V. The module has a wide high voltage range, so it can be used to power high-power LED strips, matrices, powerful lighting, etc. Also, the voltage converter can be used in the design of various power supplies, chargers and other devices. Adjustment of the DC output voltage is carried out using a multi-turn trimmer. Before connecting the module to the load, it is necessary to turn the regulator to the initial position, and then set the required output voltage. The maximum output power of the module with a heat sink installed is 70 W, and with additional cooling it is 100 W. The output current of the converter can reach up to 2 A. The efficiency of the module is about 85%. For safety reasons, the heatsink installed to the microcircuit case is isolated from it. Connecting the converter to the screw terminals is quite simple. Terminal pin assignments: IN+: input voltage 10-32V IN-: "ground" OUT+: output voltage 60 - 97 V OUT-: common load wire Power is supplied from an external power supply. The DC input voltage range of the converter is from 10 to 32 V, and the output voltage range is from 60 to 97 V. The red LED, which is connected to the power bus, indicates power supply to the module. The module is not protected against short circuit (short circuit) and reverse polarity. If you need to install reverse polarity protection, you need to connect a diode or a diode bridge to the input terminals.

— | The BTA41-600 module is an assembled resistive load power controller. The module can be used to change the power of a soldering iron, electric motor, fan, brightness of artificial lighting and other electrical devices. The maximum load power is 4000W. Please note that this inverter cannot control the power of reactive loads (consumer electronics, flashlights, etc.). The module is designed on the basis of the triac BTA41-600, which has 3 outputs and is made in the "TO-3" package. A radiator is fixed on the BTA41-600 triac housing, which provides cooling at a power of over 2000 watts. The main component of the module is a triac, the opening phase of which depends on the change in the half-wave of the supply voltage. Due to this dependence, the output power of the active load is regulated. The output voltage is adjusted using a variable resistor. The voltage value range is from 15 to 100%. The load is connected to the regulator board using a terminal block. The connection polarity is shown on the module board. The module board can be installed in the device case (there are 4 holes).

— | The TDA2030A low frequency amplifier module is designed to provide high quality medium power audio output. This amplifier can be used to build a subwoofer or to repair audio equipment. The amplifier module board is designed based on the TDA2030A chip from ST Microelectronics. The TDA2030A chip has 5 pins and is made in a Pentawatt package. The microcircuit is designed to amplify the sound signals of Hi-Fi systems with a power of up to 18 watts. The peak value of the output current is 3.5 A. In this module, the microcircuit is used as a ULF (low frequency amplifier) class AB. The microcircuit has a low coefficient of non-linear distortion, so the amplifier can reproduce good sound. Also, the microcircuit has built-in thermal protection (turns off at 145 ° C) and protection against short circuit (short circuit). For heat transfer, a heat sink is attached to the microcircuit case. If necessary, it can be easily replaced with another radiator. The module board has a trimming resistor with which you can adjust the volume level. To connect external devices to the amplifier module, pin connectors are used, and to output a signal, the speaker must be connected to the terminal block (the polarity of the terminal block is displayed on the board): VCC: 6 to 12V power supply GND: common wire ("ground") IN: audio signal input OUT: audio signal output Power is supplied from an external power source. The operating supply voltage range is from 6 to 12 V. The presence of board power is signaled by the POWER LED, which is connected to the power bus of the amplifier.

— | The kit is intended for the manufacture of a metal detector that allows you to detect objects made of ferrous and non-ferrous metals. The kit includes a set of parts, a board and a description of the assembly (the speaker is not included in the kit). Specifications: Coin detection depth 20 - 25 cm Depth of detection of large objects 100 - 150 cm Supply voltage, 9 - 14 V Current consumption, 60 - 70 mA Impulse current consumption, 1 - 2 A Board dimensions, 45 x 52 mm Circuit diagram Layout of elements General description: The device consists of two main nodes: transmitting and receiving. The transmitting node consists of a pulse generator on the NE555 chip and a powerful key on the IRF740 transistor. The receiving unit is assembled on a TL072 chip and a BC547 transistor. The excitation signal is transmitted periodically to the sensor coil, in the form of pulses with a duration of 125-150 μs and a frequency of 125-150 Hz. In conducting objects, damped eddy currents are induced, which excite a damped electromagnetic field. Depending on the conductive properties and the size of the object, the signal changes its shape and duration. Search coil manufacturing: For the manufacture of a search coil, you will need a rigid non-metallic mandrel Ø 200-250 mm, a copper winding enameled wire PEV (Ø0.4 - 0.6 mm) 20 meters long, a copper stranded insulated wire 2x1.5 mm2 120 - 150 cm long to connect the coil with payment. Wrap 25 turns of winding wire tightly onto the mandrel. Fix the ends of the wire and connect by soldering with a stranded insulated wire to the board to the contacts L1. Assembling and setting up a metal detector Solder an 8 ohm 0.5 W speaker to the SP1 contacts. The contacts P1 are powered by 9-14 V (preferably from a 12 V 1.2 Ah battery). After turning on the device, by rotating the tuning resistor R8, find a position where the clicks in the speaker will subside as much as possible, and the noise will not start to grow, after which, using the variable resistor R9, perform the same operation, but more accurately, the maximum sensitivity of the metal detector is at the threshold of sound. The sensitivity of a metal detector can be improved by changing the number of coil turns. With a mandrel diameter of 250 mm, and a winding wire of Ø0.5 mm, this is approximately 14 turns. After tuning is complete, the coil can be hardened by wrapping it with tape, electrical tape, or impregnating it with epoxy. It is recommended to varnish the soldered and debugged board. This will prevent the parameters from drifting when the environmental conditions change and ensure stable and reliable operation of the device.
