WSDMAVIS Converter Adjustable Performance Transistor Review

Consist of XL6009E1 kernel chip, which is built-in 4A high performance MOSFET switch tube, the switch frequency is up to 400KHz, transfer efficiency is up to 92%, Output ripple is less than 30mV.( It is recommended that the working current is about 2A, and the heat sink is added when the power exceeds 2A. When the power exceeds 20W, the heat sink is also required). Smaller ripple and volume, convenient to adjust output voltage by screwing rotational potentiometer. Long press the switch for more than 1 second and less than 4 seconds, the voltmeter can be turned off, short press the switch to turn on the voltmeter. Press button on right to switch voltmeter displaying input or output voltage, convenient to observe voltage change.There is an indicator light to show which terminal voltage is being measured. By default, the nixie tube displays the input voltage and the input indicator IN is on when it is turned on for the first time; touch the button, the nixie tube displays the output voltage, and the output indicator OUT is on. Press and hold the switch for more than 4 seconds to enter the voltage measurement error calibration function. At this time, the IN light is on (calibration input terminal), and the digital tube flashes to display the calibration value (the factory parameter is 0.0). At this time, short press the button to change the value (range -0.5~0.5V), positive number means upward calibration, negative number means downward calibration. After adjusting the calibration value of the input terminal, press and hold the button for more than 2 seconds to enter the error calibration of the output terminal. At this time, the OUT light is on (calibration output terminal).This module is applied to booster area that output voltage is higher than input voltage, suck as: battery, power transformers, DIY adjustable regulated power supply, 24V vehicle laptop power supply,9V to 12V, 12V to 18V, 18V to 24V etc.
