Review on ⚡️ LM2596 12V to 5V Buck Converter, DROK Adjustable DC Voltage Regulator 4-40V Step-down, 24V to 1.23-37V 12V Volt Reducer Board, 3A Power Supply Transformer Module by Vashod Reed

I installed a solar power plant in my locked cabin. When using flooded cell lead-acid batteries in my battery bank, it is important to know if their voltage drops below 60% State of Charge (SOC) to prolong battery life. They rarely go below 80%. To be active I installed a voltage monitor with built in alarm. However, the monitor is not calibrated and displayed a value of 0.3 volts that is too high. Luckily it has a calibration procedure that requires noting two voltage settings for 12 and 24 volts. Using the DROK LM2596 I was able to calibrate the voltage monitor so that it now accurately shows my battery voltage. I also used the DROK LM2596 to test the alarm point on the monitor. The DROK LM2596 proved to be a very affordable alternative to a desktop AC power supply that can cost $100. The potentiometer on the DROK LM2596 was not very sensitive. I was able to easily dial the specified voltage within 0.05 volts. I will keep it in my electronics kit for future projects.
