Function Introduction:
a. Protection function:
OVP (over-voltage protection): there is OVP at 25-30V; it will be damaged permanently over 30V.at OVP, LED show OVP, as picture 1 show)
OTP(over-temperature protection): load temperature is over  80℃, the LED show OTP, as picture 2 show.
OPP(over-power protection): the power is over  80℃, the LED show OPP, as picture 3 show.
b. Set output
recovery
mode
after load entering protection status, manual or automatic
c. View the voltage value, current value and power value of the load.
d. Intelligent temperature control fan. When the current is over 2A or the temperature is over 40℃, the fan will start.
e. Precision multiloop adjustable potentiometer: you can adjust the current precisely, upto 0.01A. so you don’t need to adjust a big current mistakenly to damage the power supply. So the power supply will not be damaged due to mistakenly adjustment
f. you can set default boot status freely, open or close.
Operation Instruction
The load is powered at the range of 4-25.0V (the input polarity cannot be reversed, otherwise the product is permanently damaged and cannot be repaired), the LED will be flashing to remind current setting value, waiting for output. Press ON/OFF button, open output to start work.
1. Adjust output current value.
Turning the rotary control clockwise increases the value and anticlockwise decreases the value. According to the needs of the situation, the potentiometer can realize coarse adjustment or fine adjustment. The fine adjustment can be accurate to 0.01A.
2, Adjust LED display status
Press “SET” to adjust the LED display status, default display output current value. Press “SET” button to display *.**A、**.*P、**.*V followed by recycling.
3. Open or close load output
Press “ON/OFF” button, you can open or close load output
4, Set load default boot status (open or close status, Factory default close status)

Press and hold “ON/OFF” button, if the LED will display “--ON”, as picture 4, the load will open output when power on next time; If the LED display”-OFF”, as picture 5 show, the LED will display current value flashing at last shutdown when power on next time, then press “ON/OFF” button to open output.
5, Set the load output
recovery
mode
after protection removed.
Press and hold “SET” button, to set output
recovery
mode
after protection removed. Press and hold “SET” button, if the LED will display “--ON”, as picture 4, and the protection was removed, the load will recover to work; If the LED display”-OFF”, as picture 5 show, and the protection was removed, the LED still show protection status, then press “ON/OFF ‘button, the display will display present setting current flashing, then press “ON/OFF‘ button again, the load recover to work.
NOTE:
Please check the output current of power bank carefully. The current of the general power bank is generally small, so adjust smaller current when the load was used.
