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.
1. LED power indicator.
2. 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).
3. Special launch, the voltmeter calibration function, will never exist voltmeter inaccurate!
