20Pcs Mini DC Adjustable Power Supply Buck Module Step Down Module
Description:
Module Properties: Non-isolated step-down module (BUCK) Rectification: Synchronous rectification Input voltage: DC 4.75V-23V Output voltage: DC 1.0V-17V (Adjustable, Output < Input) Output current: Rated current 1.8A (3A MAX, can not be prolonged) Output ripple: 30mV (no-load) Dimension: 17 x 11 x 4mm (L x W x H) / 0.67 x 0.43 x 0.16 inch approx
These are an incredible value. 96-98% efficiency means NO HEAT and NO WASTED POWER.. the days of the TO-220 1A regulator with heatsink and fan are over.
It brings shame to what I used to think was an efficient power supply after matching transformer, rectifier, heat sink, and convection cooling.
There are two; a 1.8A and a 3A and they are both terrific regulators - power supplies made simple!
** And just as a side note: they arrived faster than a similar order for FETs from Amazon!
Product corresponds to the description. Processing and quality are very good. I have bought these modules several times. Am very satisfied with them.
Have processed these modules several times, they work reliably. Until today I had no failure.
I can highly recommend a purchase.
