XL4015 75W High Power Step Down Convertor with Display

Overview:
The XL4015 D- DC Adjustable Step Down is able to drive down a 5A load with high efficiency, low ripple and excellent line and load regulation. The module comes fitted with a voltage meter to display the input voltage and output voltage.

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 can be memorized and not lost 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!

Size: 6.63.91.8CM (LxWxH)
Indicator LEDs: Green power LED and two red LEDs to show which voltage is being displayed on the Voltmeter (Input / Output)

Instructions:
The potentiometer can be used to adjust the output voltage. Clockwise to increase, and anti-clockwise to decrease
Button Short Press - Changes what is displayed on the voltmeter. Either Input Voltage or Output Voltage
Button Medium Press - Disable/Turn off the voltage display. A short press will enable the display again
Button Long Press - Enter calibration/offset mode. Display will flash once button press is released. Input and output voltages can be adjusted by 0.5V in 0.1V steps
