Completely independent of the ground (can be connected in series), beautiful, and quiet power supplies. The use of buttons is intuitive and can be figured out. The beeping can be turned off (by long pressing the voltage setting encoder), but it doesn’t remember the setting, starting with the last set U,I value. The three memory slots are also practical, as they remember the overcurrent protection (OCP) setting. The fan only turns on when the power supply is actually loaded, so there is no unnecessary disturbing noise during use. The USB voltage and current measurement is real, with a very fast display of the measurement. The current regulation is possible even in 1mA steps, the voltage in 10mV steps, but with the two encoders, each digit can be set separately, allowing rapid adjustment to the desired value. The voltage accuracy is really good, although I do not have a calibrated instrument to verify. The packaging of the device did not include extra cardboard, so one of the boxes was somewhat damaged, but the devices were surrounded by thick foams and bags, and were intact. Included are the crocodile clip wire pair and the EU power cord. It arrived in 5 days with EU direct shipping, which included a weekend.

Teljesen földfüggetlen (így sorba is kapcsolhatók), szép, és halk tápok. A gombok használata intuitív, kitalálható. A csipogás kikapcsolását (feszültség állító encoder hosszan nyomva) nem jegyzik meg, de az utoljára beállított U,I értékkel indulnak. A három memóriahely is praktikus, ezek megjegyzik a túláramvédelem (OCP) beállítást is. A ventilátor csak akkor kapcsol be ha tényleg terhelve van a táp, így nincs felesleges zavaró zajforrás használatakor. Az USB feszültéség és áram mérés valós, igen gyors a mérés kijelzése. Az áram szabályozása akár 1mA lépésekben is lehetséges, a feszültség 10mV lépésekkel, de a két enkoderrel minden helyiérték külön állítható, azaz gyorsan beállítható a kívánt érték. A feszültség pontosságuk igazán jó, bár nincs kalibrált műszerem hogy ellenőrizzem. A készülék dobozolás nem volt plusz kartonban, így az egyik doboz valamennyire sérült, de a készülékek vastag szivacsokkal és zacskóval voltak körülvéve, sértetlenek. Tartozék a krokodilcsipeszes vezetékpár, és az EU hálózati kábel. EU direct szállítással 5 nap alatt érkezett, ebben egy hétvége is volt.

Order came in 4 days from Czechia to Romania well packed and undamaged. Exactly as described. Does exactly what it says on description. I bought the TPS-C3010 model. The power cord has only 1meter. The unit has a temperature controlled fan on the back. The CV mode is automatically disabled and the CC mode kicks in if resistance of the load is smaller than the one given by the formula R=V/I. I disabled the sound from the start but after restart is re-enabled back. I guess I have to de-solder the buzzer from the board. The natural order of the power supply terminals should be with the positive on the right but on this unit is backwards. I will switch that in the future. Other than that I am very pleased with this product. Works great and the 5v USB Power supply is a very useful feature! Thank you!

The natural order of the power supply terminals should be with the pozitive on the right but on this unit is backwards. I will switch that in the future.
