DASAR ELEKTRONIKA


27 Mhz / 11 Meter

POWER SUPPLAY 13,8 Volt





Part list for 12 Amp BDX33-based power supply:

  • 2 x 15 volt 6+ amps

  • 2 times two MR750 (MR7510) diodes (MR750 = 6 Ampere diode) or 2 times 3 1N5401 (1N5408) diodes.

  • F1 = 1 Amp

  • F2 = 15 amp

  • R1 2k2 1 Watt

  • R2 10k

  • R3 1k 0.5 watt

  • R4,R5,R6,R7 0.1 ohm 10 watt

  • R8 4.7

  • R9 6k8

  • C1 two times 4700uF/35v

  • C2 330uF/35v

  • C0',C3,C4,C6,C10 100nF

  • C7 330uF/25v

  • C8 47nF

  • C9 47uF/25v

  • D1 1N5401

  • D2 LED

  • D3, D4, D5 1N4001

  • IC1 78L15

  • relay 12 volt 2x5 amp switching

  • 3 darlington transistors: T0,T1,T2 = BDX-33 NPN TO-220 transistor

  • Zd 8 or 9 volt, 5 watt

  • P1 2k trimmer

If using a bridge rectifier (like in schematic 2) you do not need 2 x 15 volts 6 amps, but 1 x 15 volt 10+ Amps

Part list for 20 Amp BDX33-based power supply:

  • 2 x 15 volt 12+ amps

  • 2 times 3 MR750 (MR7510) diodes (MR750 = 6 Ampere diode) or 2 times 5 1N5401 (1N5408) diodes.

  • F1 = 2 Amp

  • F2 = 25 amp

  • R1 2k2 1 Watt

  • R2 10k

  • R3 1k 0.5 watt

  • R4,R5,R6,R7 0.1 ohm 10 watt

  • R8 4.7

  • R9 6k8

  • C1 22000uF/35v

  • C2 330uF/35v

  • C0',C3,C4,C6,C10 100nF

  • C7 330uF/25v

  • C8 47nF

  • C9 47uF/25v

  • D1 1N5401

  • D2 LED

  • D3, D4, D5 1N4001

  • IC1 7815

  • relay 12 volt 10 amp switching

  • Four darlington transistors: T0,T1,T2,T3 = BDX-33 NPN TO-220 transistor

  • Zd 8 or 9 volt, 5 watt

  • P1 2k trimmer

If using a bridge rectifier (like in schematic 2) you do not need 2 x 15 volts 12 amps, but 1 x 15 volt 20 Amps
