That is one of the best step down regulators i have in my lab and i've just got one more. It is a bit expensive but you won't regret any cent spent on this "great toy"!

Conforme à la description, pas de notice d'utilisation et de réglage , les deux modules reçus ne fonctionnent pas .

it is a small variable power supply great for DIY stuff. if you getting fault led on try increasing overvoltage protection pot several times

Fast delivery!

Tout ok

Worked perfectly. hoping to make a PSU out of it.

Delivery time exceeded my expectation. Received item in under 2 weeks of ordering even though I was informed it could take up to 6 weeks to arrive.

very good DC-DC converter, buck and boost automatically. potentiometers for output voltage, current limit and undervoltage switch off.

parfait et envoi rapide

great product, buying the second one.
