DC to DC Buck Converter 5A Step Down Module 4-38VDC Input, 1.25-36VDC Adjustable Output with LED Display Voltage Regulator Meter

5A high efficiency reduction of voltage with low ripple Voltage display with self-correcting. 3.5V minimum input for the LED display to light. Touch the button to change input or output voltage, LED indicator light display will measuring voltage, and can auto save one voltage, press the button to turn off the voltmeter Input voltage 4.0～38V (the input voltage must be higher 1.5V than output voltage) Adjustable output voltage range: 1.25V～36V (the input voltage must be higher 1.5V than output voltage) Output power can reach 75W. Output current can reach 5A, suggested use it less than 4.5A (note: Please add a cooling or heat sink as needed. Load regulation S（I）≤0.8%, voltage regulation S（u）≤0.8% With overheating protection and short-circuit protection Size: Approx. 66 x 40 x 12MM / 2.6 x 1.57 x 0.47 inch This module can be used if input voltage is higher than output voltage. Expmples, 12V to 3.3V, 12V to 5V, 24V to 12V, 36V to 24V etc
