20 Pcs 5v Buck Converter 12v to 5v Mini Regulator Module Dc 4.5-24v 12v 24v to 5v 3a Voltage Reducer, Power Supply Transformer Module, Step-down Regulator Board DIY Electronics

Specifications

: power
input: DC 4.5 - 24V, adjustable
range: 0.8 - 17V;
Fixed output: 1.8V, 2.5V, 3.3V, 5V, 9V, 12V (can be chosen on the back);
Max output current: 3A; If the actual test input is 12V and output is 1.5A, no other system is required.
High efficiency: the voltage regulator module has high efficiency, ultra-compact size, high frequency, low ripple and stable working performance, widely applicable in fixing work and synchronous rectification; the circuit conversion efficiency is as high as 97.5 %.
Adjustable and fixed voltage output: you can get fixed output voltage by soldering the pot on the board of the regulator module; you can also adjust the fixed output voltage by potentiometer as needed.
Quality material: our buck converter is made with a quality potentiometer and 3A current chip, high current shielding inductor and MLCC solid capacitor, high current shielding inductance, ultra-low internal resistance, maximizing conversion efficiency, reducing heat generation, reliable and durable.
Simple to operate: the integrated design allows the port of the regulator board to default to keep working mode and will be closed if it is at low electric level off, and with ultra-low quiescent current of 0.85 mA; it can be connected to the car battery without a switch, car female socket or the ACC power cord, convenient to use
