POWER SUPPLY UNIT from Chinese Modules. I decided to show a variant of assembling a power supply unit/charger, an adjustable power supply unit from ready-made modules ordered in China. Such a solution is available for assembly for most people who do not have knowledge and experience in electronics. ********************************************************************************************************************************** AliExpress - http://ali.ski/zggzpr Power supply 2412 (24V 6A) - http://ali.ski/wa7TMO Voltmeter-Ammeter - http://ali.ski/uFIgQ Potentiometer knobs - http://ali.ski/_fCpMg Volt-ammeter (4 digits) - http://ali.ski/431DNl Knobs for multi-turn potentiometers - http://ali.ski/UuNZdk Step-down module 12A 0.8-35v - http://ali.ski/8sLMW DC-DC module cc cv 5a 0.8-30v - http://ali.ski/gd6i2S LM2596 module - http://ali.ski/kxxl4l Step-down module 1.3-37v - http://ali.ski/skKTG ************************************************************************************************************************************************* List of ordered: 7MBR50UA120-50 - http://ali.ski/ToxPY Hcpl-3140 - http://ali.ski/B8GLDG AliExpress - http://ali.ski/zggzpr Potentiometer knobs - http://ali.ski/_fCpMg Multi-turn potentiometer knobs - http://ali.ski/UuNZdk Schottky diodes 20200CT - http://ali.ski/Sw-d1d Schottky diodes 1620CT/CTR - http://ali.ski/nSAfg3 Irf3205 10pcs - http://ali.ski/kaPfr1 LM324N - http://ali.ski/vVTO- Potentiometers 1K Wh148 - http://ali.ski/BTNgv Potentiometers 200K - http://ali.ski/-IWGnQ BT169D - http://ali.ski/sWKxKc Power supply 2412 (24V 6A) - http://ali.ski/wa7TMO PCB paper - http://ali.ski/BHhyz MJE13009 - http://ali.ski/JYXqxY MJE13007 - http://ali.ski/zWYwMn SMD 1206 resistors - http://ali.ski/qGYmuE Resistors 0.25W - http://ali.ski/Ltzqg9 Resistors 0.25W 2.2 Ohm - http://ali.ski/Qx8o8h Volt-ammeter (4 digits) - http://ali.ski/431DNl Laser thermometer -50 +360C - http://ali.ski/VcbmYI Two-channel oscilloscope ISDS205A - http://ali.ski/DkbYy Voltmeter-Ammeter - http://ali.ski/uFIgQ Soldering iron moment 100W with a loop-shaped tip - http://ali.ski/cGkxu Soldering iron with solder feed 60W - http://ali.ski/A6Gc1E Soldering iron gun 30-70W - http://ali.ski/_Yre6O Soldering iron sponges - http://ali.ski/uXIQD HAKKO T12 soldering station KIT set - http://ali.ski/YIQaI3 Cartridges for halogen lamps MR16 MR11 G5.3 - http://ali.ski/LD26LW Cone drill set 4-12/20/32 mm + bag - http://ali.ski/fo7Nf2 Black cone drill 4-32 mm - http://ali.ski/EkibM Cone drill 4-32 mm - http://ali.ski/_gbTUu Cone drill 4-20 mm - http://ali.ski/wODE3S Set of titanium drills 50 pcs 1/1. 5/2/2.5/3 mm - http://ali.ski/2k9KR Voltmeter Ammeter 50a - http://ali.ski/sMAAU Tl494cn 10pcs - http://ali.ski/IpFLfm TL494cn 100pcs - http://ali.ski/qTzGJ Watt Meter DC 60V 100A analyzer - http://ali.ski/Y1odA NTC Thermistor 5D-11 - http://ali.ski/sOanW Step-down module 12A 0.8-35v - http://ali.ski/8sLMW LM317 voltage and current stabilizer - http://ali.ski/pFFToa Ir2153d - http://ali.ski/Q5gfu Relay 12v 12 a changeover square - http://ali.ski/BEaDVL Module DC-DC cc cv 5a 0.8-30v - http://ali.ski/gd6i2S Voltmeter-ammeter - http://ali.ski/UXl2X IRF740 - http://ali.ski/1xNKW Step-down module 1.3-37v - http://ali.ski/skKTG Diamond disks for engraver - Transistor tester - http://ali.ski/gKq7H Module on LM2596 - http://ali.ski/kxxl4l Potentiometers 10k - http://ali.ski/djEut Knobs - http://ali.ski/u8Hcyj USBASP programmer - http://ali.ski/Mp0E2 Ir2161 sop8 -http://ali.ski/CQv7P Insulating spacers TO-220 - http://ali.ski/WFQ7PN Insulating bushings TO-220 - http://ali.ski/yjIpq Set Potentiometers - http://ali.ski/yDxhO2 Multi-turn potentiometers 10k - http://ali.ski/ohzuE0 Electronic transformer 60W - http://ali.ski/nsm_6i Electronic transformer 105W - http://ali.ski/2KG4v Electronic transformer 200W - http://ali.ski/Fn6h82 Potentiometers 1M - http://ali.ski/AzfcZH Potentiometers 500k - http://ali.ski/hbxB0_ Step-up module MT3608 - http://ali.ski/iee-m5 Charger IMAX B6 Lipo Ni-mh Li-ion NI-Cd RC - http://ali.ski/HrVgN Box 9v DC holder AA 6pcs - http://ali.ski/Fn00c1 Box for AA 4pcs - http://ali.ski/aR7lP Box for AA 4 pcs (2 rows) - http://ali.ski/9zElqm AAA-to-AA adapter 4 pcs - http://ali.ski/d0P6L Li-ion 1A charge module with protection - http://ali.ski/HKcf2 LI-ion 1A charge module with protection (other connector) - http://ali.ski/5RW8d Li-ion charge module 1A - http://ali.ski/mzmFL Power supply LED 12V 20A 240W - http://ali.ski/DM1ba ***************************************************** Elixir strings 009-042 - http://ali.ski/GJTC9X Taps M3-M8 - http://ali.ski/x3SFPj Drill taps M2-M10 - http://ali.ski/FzXvOx Set for cutting threads M3-M12 - http://ali.ski/zSmFLs Taps M3-M8 with a holder - http://ali.ski/YwwGy Taps, drills with a holder - http://ali.ski/Iseci New Transistor Tester, powered by USB / Li-ion 14500 - http://ali.ski/bavGI Batteries LI-ion 3.7V 14500 - http://ali.ski/4HQzbP Scotch tape for radiators - http://ali.ski/R8K4S
