DIY DC/AC To DC LM317 Power Continuous Adjustable Voltage Regulator 1.25V-37V With Protection Kit
A part of the review has been auto-translated.
It works as expected. I power it from my solorpanel and I can regulate the output voltage. The potentiometer is not linear as expected, because usable angle is low. The con is only this potentiometer, feels cheap, but for that price cannot expect more as in my country LM317 costs almost the price of the whole device.
It's a bit simpler than it looks but it was worth the purchase, maybe I'll buy another again.
Everything is in order, the parcel arrived in good condition and in accordance with the order. Thank you very much.
Adjustable voltage regulators are really easy to do with components you probably have laying around... but for this price I would recommend you to buy this little module. You might save some time for other parts of your project. Works fine!
There was no product I originally ordered but I proposed an exchange that was accepted. I'm happy with the exchange. A good amplifier considering the price and size. Thank you, sir.
good product
This regulator is amazing. Well packaged and received ahead of time. I recommend it. Came to Portugal - Me Martins
Produto demorou de chegar,e ainda veio danificado.
Je l'ai utilisé pour fabriquer un agitateur magnétique maison. J'y ai ajouté une petite LED et ses résistances, j'ai déporté le potentiomètre pour le mettre en façade, ajouté une prise jack pour mon adaptateur 12V ainsi qu'un interrupteur. Je suis très content de ce montage, il fonctionne parfaitement et le régulateur est petit et très très bien fais. Si vous avez besoin d'un régulateur pour un petit montage ou une réparation, ne vous cassez pas la tête à en faire un vous même, celui-ci fera très certainement l'affaire. Je ne peut que recommander !
using mine to charge NiMH x 5 cell batteries, made a 3d printed enclosure, voltage is easily adjusted, charges the batteries quickly, stays cool.
