Review on 💡 Valefod LM2596 DC to DC Voltage Regulator 3 Pack - Efficient Buck Converter with LED Display by Eddie Orrell

Stable voltage at different temperatures. Needed in the car under the hood or in the car. A clamping zener diode has been added to the output to protect devices that cannot operate on 12+VDC. I have installed 6.5vdc units for stable fuel level control for older cars. These blocks hit the input voltage when something happens. So the fixing zener diode. I use 7.5 volts and add a pico fuse to the input so it outputs 0.5 amps.
