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 25W, 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 power is over 10W 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”
