I. “ON/OFF” button: press the button to open or close output. Press and hold the button to set the boot default status of open or close
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. Preci sion 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)
