Geos VIP1GR17/10/2017The product comes in antistatic bags. I tested all three of them and work perfect!
I connected in 12V to 15V DC Power Supply as Input Source, I’ adjusted for 5V Output and connected in 2.2A load. Works Very Good, I measure a little bit of noise (20 – 35 mVpp) in the Output but this is right for this switch type converters.
Quick tip: connect an Inductor same type as that who is mounted in the board in series with the (+) of output, and then connect a couple of capacitors (one 100uF Electrolytic and one 100n Ceramic) between the free leg of Inductor and the GND. THAT’S IT NOISE NO MORE!!!
I use the module and the low-pass Filter to supply +5V to an RTL-SDR and a Wide Band Preamplifier for HF Band, and the result it’s GREAT!
Seller’s service was VERY GOOD!!! Delivery Time its fast.
TOTALLY RECOMMENDED!!!Comments (0)Show Original -

I tested it with a 12Vdc power source and all the 3 power supply circuits work like a charm. the voltage adjustment is easy. satisfied and suggested
ho testato i 3 circuiti con una sorgente a 12Vdc e tutti e 3 hanno funzionato perfettamente. la regolazione con trim multigiri è OK. soddisfatto e suggerito come acquistoComments (1)Show Original -

0A:Neither. It´s a High- to Low voltage converter a "buck-converter". e.g. Input is 18V and you want Output 5V, Adjust with the pot. the Volt out to be 5V. Now the Input may wary from 6V to 30V and yet the Output stays at 5VAnswered by KIRASE on 18/04/2023Helpful (0)
