XL4015 DC DC Adjustable Step Down Board 75W 5A LED Voltmeter Power Supply Module 4.0-38V to 1.25V-36V Buck

This product is a 180 KHz fixed frequency PWM buck (step-down) DC/DC module,capable of driving a 5A load with high efficiency, low ripple and excellent line and load regulation.The module with a voltage meter to display the input voltage and output voltage, and the voltage can be corrected through the button to improve the accuracy of the voltmeter.

Features:
– LED power indicator.
– Button to switch measurement of the input or output voltage, and LED indicates the current measurement of the input or output voltage; The nixie tube can be turned off by another button. Mentioned states are able to be memorized, is not lost even if the power is disconnected. (On-board marked “IN” LED is turned on, the nixie tube display input voltage value, “OUT” LED bright display is the output voltage value).
– Special launch, the voltmeter calibration function, will never exist voltmeter inaccurate!
