It's good item

Muito satisfeito com o compra e a qualidade do produto! Chegou em perfeito estado!

Produit conforme, envoi rapide.

I like the onboard voltmeter, and particularly the fact that the display can be turned off (the buck power converter is still operational). The display can also be switched to show either input or output voltage. Nice. The voltmeter did measure sbout 02 volts different than my test equipment. And the output voltage level is not completely independent of input level. Say I want 5V output, and supply 10V, and trim the output, then if I push the input voltage up to 20V the output climbs to 5.3V,

There are no instructions for the switches but it is simple to work out that the left hand switch turns on and off the display, where the right hand switch toggles between input and output voltage.

Отличный регулятор напряжения! Спасибо продавцу за хороший товар, рекомендую!

Very good input-output characteristics, good adj range with low ripple and fast response. A good buy at twice the cost.

Good quality product, very useful.
