Testing this device yielded the pleasant surprise that this TPS305 is a very good performing power supply for the money you have to pay for it. We can think of very few criticisms. Obviously, professional electronics engineers will turn their noses up at a power supply that delivers a rms-ripple of around 30 mV at full load. But don't forget that this ripple drops to 6.5 mV if you reduce the current from full load (5 A) to 4.0 A. We think that this is an excellent value.
Also, the fact that in all our tests no overshoots, spikes or oscillations of any kind occurred on the output voltage argues in favour of the designers of this power supply. We have tested several power supplies in the same price range where this was anything but the case.
For any hobbyist about to purchase a universal lab power supply, we think the TPS305 is an excellent choice.

Оба источника питания полностью проверены. Все данные соответствуют заявленным производителем. Качество изготовления хорошее, за исключением выходных гнёзд. Они изготовлены из мягкого цинкового сплава и резьба портится при небольшой нагрузке. Конечно лучше сменить гнёзда на латунь. В отличии от аналоговой регулировки очень удобен в работе.

Both power supplies are fully tested. All data corresponds to the manufacturer's claims. The quality of manufacturing is good, except for the output sockets. They are made of soft zinc alloy and the thread gets damaged under slight load. It is certainly better to replace the sockets with brass. Unlike analog adjustment, it is very convenient to work with.
