It does not regulate
Checking if the problem could be the potentiometer, as input 5V, I get 5V ouput, but does not regulate to any other voltage.Potentiotemer touch the inductor,, then electrical problem, guess I already damage two, lets see with the others.

Reviewed in Germany on 12 June 2024

Nehme ich für Schiffsmodellbauzwecke, um einen Mini-Radarmotor auf die richtige Geschwindigkeit zu regeln.

Klappt gut damit.

Die Einstellung ist mit dem Trimmpoti aber etwas fummelig.

Kann ich weiterempfehlen.

Reviewed in Germany on 17 September 2024

Die Teile sind für die Tonne. Der Schleifer des Einstellpotentiometers schleift an einem Kontakt des danebenliegenden Kondensators. Der Schleifer klemmt und die Ausgangsspannung kann nicht richtig eingestellt werden.

Leider ist das Potentiometer zur Einstellung der Ausgangsspannung nach einigen Einstellungen nur mehr sehr schwer drehbar, aber für den Preis/Stk ok.

2.0 out of 5 stars Ausgangsspannung nicht 1-17V sondern nur 6.2-17V!!
Reviewed in Germany on 16 October 2024
Verified Purchase
Mit dem verbauten Poti lässt sich die Spannung nur runter bis 6.2V einstellen. Es muss auf den freien Pins ein Parallelwiderstand hinzugefügt werden, damit die Spannung bis runter auf 1V eingestellt werden kann. Die Ausgangsspannung berechnet sich wie folgt: Vout = 0.923*(R1+R2)/R2 Wobei R2 fest 8kOhm ist und R1 (Poti) im Bereich 40...200kOhm eingestellt werden kann. Mit einem Parallelwiderstand von 39kOhm kann dann noch 3.2...4.7V eingestellt werden. Das Foto im Artikel entspricht nicht dem Print, es hat noch Lötpunkte parallel zum Poti auf denen eben ein Widerstand aufgelötet werden könnte.
