QTY:
This DC-DC power supply module is digitally controlled step-down power with digital display, high power, high efficiency, stable performance. Input voltage 6-40V and output 0-32V, output current 0-5A; with LED digital display, it can display the output voltage/current, preset voltage/current and other parameters in real time.

Features:
Can precisely regulate the output voltage and current.
Store setting value automatically: when power on next time, the default working state is the stored state.
Fully digital display, easy and convenient to use.
CC and CV indication: lED will lights corresponding to show CV or CC state.
Digital LED display the output voltage, current and other parameters in real time.
Open or close output by pressing "ON/OFF" button.
Can set output voltage and current by pressing "SET" button.
Switch input and output display function.

Operating Instructions:
1. Open or close output: press ON/OFF button one time to open or close output in any state; press again, output will be closed or open, followed by recycling. When closed output, the LED display will show "OFF"
2. Set output voltage and current: Press SET shortly, the led display will be blinking. You can press the two buttons (+ key and - key) on the tube left to increase or decrease the value. Press SET key shortly again to switch 0.01V to 0.1V to 1V to 0.01A to 0.1A to 1A to exist adjustment, followed by recycling. At the corresponding value place, you can press the two buttons (+ key and - key) to increase or decrease the value. if you don't press the set key, the set mode will be automatically exited after 6s and the current set value will be automatically stored.
3. Switch input and output display: At no output state, press the two buttons on the tube left (IN key and OUT key) to switch the tube display between the current input voltage and the current output voltage. When show input voltage, "IN" LED lights; when show output voltage, "OUT" LED lights. 4.
4. CC and CV indication: When the module is in the state of constant voltage (CV) or constant current (CC), the CC or CV led will lights correspond to show CV or CC state.
5. Output current zero calibration: In the no-load state, Keep pressing SET key to power on, when the led display flashed, the calibration is done. Then you can loosen the SET key.
6. Store set value automatically: in operation process, the led display state, output current and output voltage setting value and output state are automatically stored. When power on next time, the default work state is the stored state.

    Die Spannung lässt sich mit 2 Stellen nach dem Komma einstellen, der Strom sogar mit 3 Stellen. Die Leerlauf- Stromaufnahme liegt bei ca. 50 mA, bei 20 V am Eingang. Die Spannungsanzeige lässt sich zwischen Ein- und Ausgang umschalten. Zum Testen von Schaltungen bestens geeignet.

    Betreibe es mit einem Laptop Netzteil. Kann CC und CV gleichzeitig. Super wenn man mal eben 5 oder 12V zum testen braucht (bench power supply)

    Mit bangen habe ich die Lieferung erwartet, da nicht klar aus der Beschreibung hervor ging, ob das Modul sich den eingestellten Betriebszustand nach einem Spannungsausfall merkt. Jetzt eben im Testbetrieb konnte ich alles zu meiner Zufriedenheit testen: Einstellung von maximaler Spannung und maximalen Strom ist einfach, durch wählen der Dezimalstelle fein oder Grob einzustellen. Diese Einstellung ist auch im OFF-Zustand möglich, so dass man eine Einstellung vorwählen kann und dann erst "die Elektronen" auf den Verbraucher frei gibt. Das Modul merkt sich alle Einstellungen auch nach entfernen aller Spannungsquellen. Wurde eine Spannung und eine Strombegrenzung eingestellt so bleibt diese erhalten. Auch der Betriebszustand OFF oder ON wird gespeichert, so dass bei abgeschalteter Ausgangsspannung und Unterbrechung der Stromversorgung nach anlegen der Stromversorgung auch die Ausgangsspannung abgeschaltet bleibt. Auch im umgekehrten Fall, Spannungsausfall und Betrieb war auf ON geschaltet, beginnt die Spannungsversorgung mit einer kleinen Verzögerung unter einer Sekunde wieder ihren Betrieb. Zur Strombegrenzung gibt es nicht viel zu sagen, außer dass man hier wirklich bis auf 1mA herunter regeln kann. Im Test habe ich einen kleinen Motor aus einem Handy mit der Einstellung 12mA Strombegrenzung und einer Maximalspannung von 3 Volt angeschlossen und unterschiedlich belastet. Die Regelung nimmt dann die Spannung zurück, wenn der eingestellte Maximalstrom erreicht ist und begrenzt damit den Strom auf den eingestellten Wert. So soll es sein. Für meinen geplanten Einsatz ist dies ein ideales Modul, nur leider lassen sich bei Dauerbetrieb die Anzeigen nicht abschalten. Jedenfalls habe ich das noch nicht herausbekommen und hätte eventuell das Modul mit den abnehmbaren Displays nehmen sollen. Mein altes lineares 3A-Labornetzgerät werde ich mit solch einem Modul demnächst aufrüsten. Dann fällt einiges an Verlustleistung weg. Werde also dieses Modul wieder kaufen. PS: Witzig fand ich die beigefügte Anleitung in Chinesisch und englisch. Dort wird als erstes Beschrieben, was man tun soll, wenn das Modul abbrennt --> Raum verlassen. Dann folgt eine lange Aufzählung, was man alles falsch machen kann und damit das Modul zerstören kann (abbrennt). Irgend wann kommen dann doch kurze Informationen was die vier Taster zu bedeuten haben ...
