    tento menič napätia a prúdu je Ok. funguje správne. nemám s ním žiadne problémy. len je potrebné vymeniť regulátory za otočné a väčšie. som spokojný this voltage and current converter is Ok. works properly. I have no problems with it. it is only necessary to replace the regulators with rotary and larger ones. I am satisfied

    Arrived with a heatsink's bent corner, and a trimmer awry soldered. Tightening the clamps, I have fear of breaking them or to strip the screws because are not so robust. So the clamping of the cable is uncertain and, checking as usual, sometimes you can remove it from the clamp with only a modest force. Thre's no indication of which is voltage regulation trimmer (right one, looking from trimmers' side) and current trimmer (left one). Tested at 3,7 Amp it heats up enought to be not possible to touch the heatsink, above all the one on the supply IN side, so I wouldn't use it at its maximum current, even with ventilation. Voltage and current regulation are good and stable. Arrivato con un angolo del dissipatore piegato ed un trimmer saldato storto. Nello stringere i morsetti si ha paura di romperli o di spanare la vite perchè non sono molto robusti. Il serraggio del cavo è perciò incerto e, controllando come di norma, talvolta lo si sfila dal morsetto applicando solo una modesta forza. Non vi è indicazione di quale sia il trimmer per regolare la tensione (a destra, guardando dal lato trimmer) e quale per la corrente (a sinistra). Testato a 3,7 A scalda già abbastanza da non poter tenere la mano a contatto con il dissipatore, soprattutto quello lato ingresso, per cui non lo utilizzerei alla massima portata di corrente, anche se con ventilazione. La regolazione della tensione e della corrente è buona e stabile.
