Product introductionAs long as you have a mobile phone charger and a USB 5V adapter, you can input it at willThe output voltage is adjustable from 1V to 24V, and the power is 3W. It can also be equipped with USBAdapter board, mincro USB as input, very convenient to use, voltageThe regulator adopts multi turn precision long handle potentiometer, which can be adjusted manually without using a slotted screwdriver. With exquisite shell,The output voltage display is divided into green light and red light for your choice.

Product highlights1: Adopt numerical control technology and adjust the voltage by pressing the key.2: It is very convenient to use. Plug in USB and you can output 1.0V -24vAdjustable voltage of.3: One key on / off output.4: Power failure stores the state before power failure.5: Voltage and current can be self calibrated.

Tips: This product is not a high-power power supply, please use it within the power range.Output voltage 1.0V, used within 2W.Output voltage 2v~24v, used within 3W.This product has various software protection functions. When the output current is greater than 2a,There will be overcurrent protection (OCP); When overpower is used, there will be over power protection (OPP), and the output will be automatically closed after protection,And display the corresponding protection (lvp/ocp/opp).

Note: Supa (double digital tube): display voltage and currentSup (single digital tube): only display voltageVoltage accuracy: (± 0.5% +1 word)Current accuracy: (± 1% +2 words)Voltage and current accuracy can be self calibratedPress and hold any key to power on the product. After 5 seconds, the nixie tube displays "8.8.8", enter the self calibration mode, and the voltage flashes,Calibrate the voltage by briefly pressing the up/down button; After long pressing any key for 2 seconds, the current flashes. By short pressing up/downPress the key to calibrate the current. After the calibration is completed, press and hold any key for 5 seconds to exit the calibration mode.
