تحت التجربة

The goods were well packed I haven't tried yet but it looks good. I recommend a good price.

Works nicely. Note: doesn't include the heat sink in photo.

This set is very well packaged in a pretty hard plastic case with a groove that maintains the LM317 in the right position. No tested yet but everything seems OK.

Полностью работающие преобразователи LM317T. Вполне возможно, что оригинальные. Все работают, на термозащиту не проверял, но в чужом обзоре этого лота видел проверку - защита при перегреве срабатывает.

It is effective and suitable for projects It has been successfully tested

Good old LM317 for a power supply project. Pop some heatsink on the back and boom boom ya got yerself a decent PSU. No pins bent everything works good on ya banggood.
