Functions:
The module has two buttons: IN/OUT for switching the display between the input and output voltage. ON/OFF for On/Off.
DC potentiometer for current regulation, once the load reaches the set current, it enters constant current mode.
CV potentiometer for voltage regulation.
Instructions for use:
Used as a voltage booster module:
- Adjust the voltage in the CV potentiometer (you can see it on the display while adjusting).
- Measure the current at the output terminals with a multimeter and adjust the DC potentiometer to the desired value.
Used in this way, the output voltage can have a drop of 0.2V.
Used as a battery charger:
- Due to the constant current function, the accumulators will be constantly charged with the same current.
- Set the charging voltage (example for 3.7V lithium, set the voltage to 4.2V).
- Set the maximum charging current to the required value, usually 0.5C or 1C (for example, with a 2000mAh battery, you can safely charge with 0.5C, i.e. 1Ah), using a multimeter.
- Connect the battery.
Used as a source for LED

Functioneaza foarte bine.Am achizitionat acest modul de curand,dar pana acum merge f.bine.Si livrarea a fost rapida.Felicitari.
Funcsional! Site serios! Felicitari!
Sursa merge perfect, exact ca in specificatii. Pana in 3A isi face treaba. Totusi, nu am reusit sa aprind un bec de 12V/55W (adica 4,6A). dintr-o sursa liniara de 3A am reusit sa il aprind fara probleme, bineinteles ca la aprox. jumatate din putere, dar macar l-am aprins.
Prea si calitate ok
Buna ziua ! Am achizitionat de la dv acest modul coborator-ridicator de tensiune si l-am folosit la incarcarea unor acumulatori litiu-ion. A mers f bine dar acum nu mai pot creste tensiunea peste 4 volti, ma puteti ajuta cu un sfat, va rog a Oare s-a ars o piesa electronica si daca da, cum as putea sa-l refac a Multumesc mult !
