5Pcs DC-DC with LED Display Voltmeter Buck Converter Step-Down Regulator 4.0-40V to 1.25-37V DC 36V to 24V to 12V to 5V Power Supply Module Compatible with Car Motor Buck
- About this item
- The buck converter provides a stable output with a voltage conversion efficiency of up to 96%. The output voltage can be adjusted continuously between 1.25V and 37V, with an input voltage requirement being at least 1V higher than the output voltage. The output current is 2A for normal operation and can reach a maximum of 3A.
- The digital display can be turned on or off to show either the input or output voltage. Featuring an advanced voltage microprocessor with self-calibration, the voltmeter has an accuracy of ±0.1V and accepts input voltages of DC 0~40V. To ensure accuracy, the input voltage should be above 4V.
- Note: This is a buck module. The input and output connectors cannot be reversed. A heat sink is required for continuous operation above 2A/15W. When using for the first time, turn the potentiometer counterclockwise more than 10 times.
- Press the button next to the voltmeter to test the input or output voltage. The green LED lights up when testing output voltage, while the red LED lights up when testing input voltage. Press the button for 1 to 4 seconds, and the voltmeter will turn off upon release; the voltmeter is very accurate.
- Analog control: Use a mini screwdriver to adjust the output voltage by turning the screw; turn clockwise to increase voltage and counterclockwise to decrease voltage.
- Size: 4.1 x 3.9 x 1 inches.
