{"product_id":"elektor-low-noise-lab-power-supply","title":"Elektor Low-Noise Lab Power Supply","description":"\u003cp\u003eThe Elektor Low-Noise Lab Power Supply is a fully analogue, adjustable, medium-power symmetrical bench supply that contains no switching or digital components. It provides an output voltage adjustable between 0 V and ±22 V, and an output current adjustable from 0 A to 1 A. Because it avoids any form of switching circuitry, the design delivers extremely low noise. To display both output voltages and currents, four miniature moving-coil panel meters are used.\u003c\/p\u003e\n\u003cp\u003eMost modern laboratory power supplies and AC adapters employ switch-mode techniques. Even the best examples inevitably exhibit high-frequency ripple and other switching artefacts on their output, which can interfere with the testing of sensitive analogue circuits and disturb low-level measurements. To overcome this, the concept here is a completely analogue power supply. Although less efficient than its switch-mode counterparts, the reduced efficiency is of little importance for test-bench use and ensures cleaner, more reliable measurement results.\u003c\/p\u003e\n\u003cp\u003eBecause many analogue circuits require a symmetrical supply, this design delivers positive and negative output voltages of equal magnitude. A small amount of adjustment is available to compensate for any imbalance. Naturally, a variable current-limit function is also included.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage\u003c\/td\u003e\n\u003ctd\u003e0…+22 V, 0, −22 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Current\u003c\/td\u003e\n\u003ctd\u003e0…+1 A, 0…−1 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd rowspan=\"2\"\u003eNoise\u003c\/td\u003e\n\u003ctd\u003e−85 dBV, (at 0.95 A\/20 V, B = 22 kHz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e−84 dBV (at 0.95 A\/20 V, B \u0026gt; 500 kHz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRipple\u003c\/td\u003e\n\u003ctd\u003e50 µVRMS (at 950 mA\/20 V, B = 22 kHz, mainly 100 Hz component)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eIncluded\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e3x PCBs: Regulator (PCB-1), Mains Filter (PCB-2) and Transformer (PCB-3)\u003c\/li\u003e\n\u003cli\u003eAll the components except the AC transformers\u003c\/li\u003e\n\u003cli\u003e4x moving-coil meters\u003c\/li\u003e\n\u003cli\u003eAdditional parts for wiring (wires, banana sockets, IEC Power entry module, etc.)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eNot included\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eThe three AC transformers\u003c\/li\u003e\n\u003cli\u003eAn enclosure\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eParts List\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eFor the Regulator PCB (240386-1)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eResistors (250 mW, 1%)\u003c\/em\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eR1 = 12 Ω\u003c\/li\u003e\n\u003cli\u003eR2, R8, R37, R62 = 1 MΩ\u003c\/li\u003e\n\u003cli\u003eR3, R7, R10, R13, R17, R20, R22, R30, R35, R42, R45, R47, R55, R60 = 100 Ω, 600 mW\u003c\/li\u003e\n\u003cli\u003eR4, R5 = 4.7 kΩ\u003c\/li\u003e\n\u003cli\u003eR6 = 100 kΩ\u003c\/li\u003e\n\u003cli\u003eR9, R12, R14, R36, R38, R39, R61, R63, R66, R72, R78, R79 = 10.0 kΩ, 600 mW\u003c\/li\u003e\n\u003cli\u003eR11 = 9.76 kΩ, 600 mW\u003c\/li\u003e\n\u003cli\u003eR15, R40 = 44.2 kΩ, 600 mW\u003c\/li\u003e\n\u003cli\u003eR16, R41, R77 = 1 kΩ\u003c\/li\u003e\n\u003cli\u003eR18, R43 = 1.5 kΩ, 1 W, 5%\u003c\/li\u003e\n\u003cli\u003eR19, R44 = 470 Ω, 1 W, 5%\u003c\/li\u003e\n\u003cli\u003eR21, R46 = 330 Ω, 600 mW\u003c\/li\u003e\n\u003cli\u003eR23, R24, R48, R49 = 1.0 Ω, 1 W\u003c\/li\u003e\n\u003cli\u003eR25, R50 = 1 kΩ, 1 W, 5%\u003c\/li\u003e\n\u003cli\u003eR26, R28, R51, R53 = 1.000 kΩ 0.1%, 15 ppm\/C\u003c\/li\u003e\n\u003cli\u003eR27, R29, R52, R54 = 10.00 kΩ 0.1%, 15 ppm\/C\u003c\/li\u003e\n\u003cli\u003eR31, R56 = 1.2 kΩ, 1 W, 5%\u003c\/li\u003e\n\u003cli\u003eR32, R57 = 47 kΩ\u003c\/li\u003e\n\u003cli\u003eR33, R58 = 270 Ω\u003c\/li\u003e\n\u003cli\u003eR34, R59 = 27 kΩ\u003c\/li\u003e\n\u003cli\u003eR64, R69 = 12.0 kΩ\u003c\/li\u003e\n\u003cli\u003eR65 = 3.0 kΩ, 600 mW\u003c\/li\u003e\n\u003cli\u003eR67, R80 = 470 Ω, 600 mW\u003c\/li\u003e\n\u003cli\u003eR68, R70 = 6.8 kΩ, 600 mW\u003c\/li\u003e\n\u003cli\u003eR71 = 30.0 kΩ,, 600 mW\u003c\/li\u003e\n\u003cli\u003eR73, R74, R75, R76 = 10 MΩ\u003c\/li\u003e\n\u003cli\u003eP1, P2, P3 = 10 kΩ, 200 mW, 20%, potentiometer, 1 turns, single, lin., panel mount\u003c\/li\u003e\n\u003cli\u003eP4, P5 = 500 Ω, 500 mW, 10%, trimmer, 25 turns, 3296Y-1-501LF Bourns\u003c\/li\u003e\n\u003cli\u003eP6, P7 = 10 kΩ, 500 mW, 10%, trimmer, 25 turns, 3296Y-1-501LF Bourns\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eCapacitors\u003c\/em\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eC1 = 100 nF, 50 V, 10%, ceramic X7R, LS 5 mm\u003c\/li\u003e\n\u003cli\u003eC2, C3, C6, C7, C30 = 10 µF, 63V, 20%, LS 2.5 mm, 3000hours@105°C\u003c\/li\u003e\n\u003cli\u003eC4, C5, C8, C9, C13, C14, C18, C19, C23, C24, C28, C29, C31, C32, C38, C39 = 100 nF, 250 V, 10%, PET, LS 7.5 mm\u003c\/li\u003e\n\u003cli\u003eC10, C20 = 47 nF, 100 V, 5%, PET, LS 5 mm\u003c\/li\u003e\n\u003cli\u003eC11, C21 = 10 nF, 100 V, 5%, PET, LS 5 mm\u003c\/li\u003e\n\u003cli\u003eC12, C22 = 220 µF, 35 V, 20%, 0.024 Ω, LS2.5\/3.5 mm, Ir 3.4 A, 2000hours@125°C, polymer\u003c\/li\u003e\n\u003cli\u003eC15, C25 = 120 µF, 50 V, 20%, ESR 0.02 Ω, Diam. 10 mm max., LS 5 mm\u003c\/li\u003e\n\u003cli\u003eC16, C26 = 15 nF, 100 V, 5%, PET, LS 5 mm\u003c\/li\u003e\n\u003cli\u003eC17, C27 = 47 nF, 100 V, 5%, PET, LS 5 mm\u003c\/li\u003e\n\u003cli\u003eC33, C34 = 22 µF, 50 V, 20%, LS 2 mm, 10000 hours @ 105°C\u003c\/li\u003e\n\u003cli\u003eC35, C36, C44, C45 = 1 µF, 100 V, 10%, LS 5 mm, ceramic X7R\u003c\/li\u003e\n\u003cli\u003eC37 = 100 uF, 50 V, 20%.
