5 pieces LM2596S DC-DC LM2596 with LED voltmeter display voltage difference converter step-down regulator 4.0-40 volts to 1.25-37 volts DC 36 volts to 24 volts to 12 volts

LM2596 buck converter produces with stability, efficiency of voltage conversion reaches up to 96%. The output voltage is 1.25 volts-37 volts (continuously adjustable, input voltage must be higher by 1 volt than the output voltage), the output current is 2 amps (normal and stable), the maximum is 3 amps. The digital display can be turned on or off to show input or output voltage. With advanced precise voltage processor, self-calibration, and voltmeter error ± 0.1 volts, the DC input voltage is 0 ~ 40 volts. (Note: To ensure voltmeter accuracy, please make sure the input voltage is higher than 4 volts). Note: This is a back unit. Input and output connectors cannot be reversed. The input voltage must be higher than the output voltage. A heatsink is required for long-term operation above 2A/15W. When used for the first time, it is necessary to turn the voltage meter more than 10 times counterclockwise. Press the button next to the voltmeter to test input or output voltage. Green LEDs light up when testing output voltage; red LEDs light up when testing input voltage. Press the button for 1 to 4 seconds, and the voltmeter will turn off when you release; the voltmeter is highly accurate. Analog control: use a small screwdriver to increase or decrease the output voltage by adjusting the screw, clockwise to raise the voltage and counterclockwise to lower the voltage.
