Ripple Peak: About 100mV
Voltage Meter Error: ± 0.1V
Keep output under 2A (or 15W), and use a heat sink when for a long time working
Wiring connection:
IN+: connect IN+ to your Input Positive
IN-: connect IN- to your Input Negative
Out+: connect OUT+ to your Output Positive
Out-: connect OUT- to your Output Negative

Applications:

Experiment teaching

Temporarily set up power supply in the outdoor

Car(audio, electric fan)power supply

How to calibrate the digital tube voltmeter:

Optional steps for the person who need a highly accurate voltage value

1.Short press the left "ON/OFF" button to start up the digital tube voltmeter. Long press(>1s, <4 seconds) the left button to shut down the digital tube voltmeter.

2.Long press(>4 seconds) the left button to enter self-calibration of voltage measurement(calibration range: -0.5-0.5V, factory setting is 0.0).

"IN" indicator lights = input voltage measurement calibration starts.

Then, long press(>2 seconds) the right "Mode" button, "OUT" indicator lights = output voltage measurement calibration starts.

Tap the left / right button to reduce / rise by one unit (since the voltage value of one unit is less than 0.1V,

you need to 1-5 times tap the button continuously, so that the voltmeter can change by 0.1V)

3.After calibration, long press(>2 seconds) the right "Mode" button to preserve the adjusted value(no loss with outage) and back to normal voltage display.
