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.

It can be used to test Z-diodes up to a maximum of 54 V. Thanks to a 60-V step-up converter, the device can be powered by the usual 5 to 12 V.\u003c\/p\u003e\n\u003cp\u003eThe principle of this tester is straightforward. A Z-diode or other DUT (device under test, such as an LED) is biased by an adjustable current source. The voltage across the DUT can be measured with a multimeter. The voltage of most (small) Z-diodes is specified at a current of 5 mA. Depending on the application, the voltage at other currents can also be of interest. That is why six current settings are available: 1, 2, 5, 10, 20, and 50 mA. LEDs are often specified at a current of 20 mA.\u003c\/p\u003e\n\u003cp\u003eWhat can be tested is:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWhether a Z-diode is defective (short circuit or high impedance).\u003c\/li\u003e\n\u003cli\u003eWhether a Z-diode exhibits the correct Z-voltage.\u003c\/li\u003e\n\u003cli\u003eHow a Z-voltage changes with different currents.\u003c\/li\u003e\n\u003cli\u003eWhat exact voltage is present at an integrated voltage reference.\u003c\/li\u003e\n\u003cli\u003eWhether LEDs in a series chain differ in brightness (hence the 20 mA current).\u003c\/li\u003e\n\u003cli\u003eWhat the current gain is for different base currents in (power) transistors.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe kit contains all parts listed in the bill of materials including PCB and enclosure.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply voltage\u003c\/td\u003e\n\u003ctd\u003e5…12 V\/2 A (USB-C)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupply current (Itest = 50 mA)\u003c\/td\u003e\n\u003ctd\u003e1.1 A @ 5 V \/ 412 mA @ 12 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSelectable currents\u003c\/td\u003e\n\u003ctd\u003e1, 2, 5, 10, 20, and 50 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax. test voltage\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;54 V @ Itest ≥1 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax. output voltage\u003c\/td\u003e\n\u003ctd\u003e60 V @ Itest = 0 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage limit at 5 V\u003c\/td\u003e\n\u003ctd\u003e4.5 V @ Itest = 1 mA \/ 5.18 V @ Itest = 50 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnclosure dimensions\u003c\/td\u003e\n\u003ctd\u003e110 x 82 x 44 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePCB size\u003c\/td\u003e\n\u003ctd\u003e105.4 x 67.3 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd rowspan=\"3\"\u003eConnections\u003c\/td\u003e\n\u003ctd\u003e4 mm banana sockets for multimeter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2 mm banana sockets for test clips\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUSB-C socket for power supply\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eIncluded\u003c\/h2\u003e\n\u003cp\u003e\u003cem\u003eResistors\u003c\/em\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eR1 = 3.3 kΩ, 600 mW, 1%\u003c\/li\u003e\n\u003cli\u003eR2 = 0.15 Ω, 1 W, 5%, LS 12.7 mm, ø 3.5 mm\u003c\/li\u003e\n\u003cli\u003eR3, R8 = 180 Ω, 600 mW, 1%\u003c\/li\u003e\n\u003cli\u003eR4, R6, R16 = 1 kΩ, 600 mW, 1%\u003c\/li\u003e\n\u003cli\u003eR5, R19 = 47 kΩ, 600 mW, 1%\u003c\/li\u003e\n\u003cli\u003eR7 = 3.9 kΩ, 1 W, 5%, LS 12.7 mm, ø 3.5 mm\u003c\/li\u003e\n\u003cli\u003eR9, R10, R12 = 10 kΩ, 600 mW, 1%\u003c\/li\u003e\n\u003cli\u003eR11, R13 = 100 Ω, 600 mW 1%\u003c\/li\u003e\n\u003cli\u003eR14 = 249 Ω, 600 mW, 1%\u003c\/li\u003e\n\u003cli\u003eR15 = 499 Ω, 600 mW, 1%\u003c\/li\u003e\n\u003cli\u003eR17 = 2.49 kΩ, 250 mW, 1%\u003c\/li\u003e\n\u003cli\u003eR18 = 4.99 kΩ, 250 mW, 1%\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eCapacitors\u003c\/em\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eC1 = 470 uF \/ 35 V, 20%, Ir = 1.86 A, ø 12.5 mm, LS 5 mm, ESR = 0.038 Ω (Panasonic EEUTP1V471)\u003c\/li\u003e\n\u003cli\u003eC2 = 1 uF \/ 100 V, 10%, X7R, LS 5 mm\u003c\/li\u003e\n\u003cli\u003eC3 = 2.2 nF \/ 50 V, 10%, X7R, LS 5 mm\u003c\/li\u003e\n\u003cli\u003eC4, C7 = 100 nF \/ 100 V, 10%, X7R, LS 5 mm\u003c\/li\u003e\n\u003cli\u003eC5 = 100 uF \/ 100 V, 20%, ø 14 mm max., LS 5 mm\u003c\/li\u003e\n\u003cli\u003eC6 = 1 nF \/ 100 V, 10%, X7R, LS 5 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eInductor\u003c\/em\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eL1 = 100 uH, Irms = 2.4 A, Isat = 3.5 A, 0.09 Ω, radial, pitch 2.5\/5\/10 mm, ø 14 mm max.
