EPLZON LM2596S Buck Converter Buck Module DC-DC 3.2-35V to 1.25-30V 3A Voltage Adjustable Buck Converter Module(Pack of 6 Pcs)

EPLZON LM2596S Buck Converter Buck Module DC-DC 3.2-35V to 1.25-30V 3A Voltage Adjustable Buck Converter Module(Pack of 6 Pcs)

All use SANYO solid-state capacitors, 36u thick circuit board, high-Q value and high-power inductor with output LED indicator lights Product parameters: The input voltage is DC 3.2-35V, the output voltage is 1.25V-30V (continuously adjustable, the input voltage must be 1.5V higher than the output voltage), the maximum output current is 3A, the conversion efficiency is 92% (maximum), the output ripple is less than 30mV, the switching frequency is 65KHz, and the working temperature is -45°C to 85°C. Note: This is a voltage reduction module. The input and output connectors cannot be reversed. The input voltage must be higher than the output voltage. It is recommended to use a current of less than 2.5A for long-term work. If it exceeds 2A, a heat sink (output of over 10W) should be added. When using it for the first time, the potentiometer must be turned counterclockwise at least 10 times. IN+input positive pole, IN - input negative pole; OUT+output positive pole, OUT - output negative pole, please note that the input and output cannot be reversed, as it may burn out if reversed! Application: The LM2596 step-down converter can be used in fields where the input voltage is higher than the step-down output voltage, such as batteries, power transformers, vehicle mounted voltage stabilizers, and system operating voltage testing EPLZON LM2596S Buck Converter Buck Module

How to Calibrate the Digital Tube Voltmeter
(Optional steps for the person who need a highly accurate voltage value)
➤Short press the left "ON/OFF" button to start up the digital tube voltmeter. Long press(>1s, 4 seconds) the left button to enter self-calibration of voltage measurement(calibration range: -0.5-0.5V, factory setting is 0.0).
"IN" indicator lights = input voltage measurement calibration starts. Then, long press(>2 seconds) the right "Mode" button, "OUT" indicator lights = output voltage measurement calibration starts.
Tap the left / right button to reduce / rise by one unit (since the voltage value of one unit is less than 0.1V,
you need to 1-5 times tap the button continuously, so that the voltmeter can change by 0.1V)
➤After calibration, long press(>2 seconds) the right "Mode" button to preserve the adjusted value(no loss with outage) and back to normal voltage display.

Kindly Note:
☑ Input voltage must be 1.5 V higher than the output voltage, no boost
☑ Do not reverse the input and output interface
☑Current work long hours is recommended for use in less than 2.5A, while adding bulkHeat sink (10W output above),
because it is the step-down module, in order to ensure stable output Set,please keep the minimum 1.5V differential.
