Module Description:

CC Indicator: on when at constant current mode
(amp value reaches the limited value).
ON Indicator: on when output is on.
Micro 5V Input
Solder terminal
DC 5-12V input
USB male 5V input
CC Potentiometer: adjust limited current
Right Button: short press to switch display output voltage/current/power
or display the parameter in turn; long press to enter/exit calibration mode.
Left Button: short press to switch ON/OFF or decrease value when at calibration mode;
long press to set output default ON/OFF after power on.

Parameter:

1. Input voltage: DC 4-13V
When use solder terminal to input, please connect the wires
correctly.
2. Output voltage: DC 0.5-30V
3. Output current: 0-2A
When under constant voltage mode, the output current is
determined by the load and cannot be adjusted manually.
If the limited current you set is 1A, then when the load
current is larger than 1A, it will enter constant current mode
and output 1A max.
4. Output power: 15W max
When output power is higher than 15W, it will shut down
CV Potentiometer:
output automatically and display –OP-. After decreasing
adjust output voltage
the load power, press ON/OFF button.
0.5-30V
5. Voltage resolution: 0.1V
Default accuracy:±0.1V

Output Can be manually adjusted if you need a higher accuracy.

6. Current resolution: 0.01A
Measurement range: 0-2.2A
Default accuracy: ±0.05A
When output current is lower than 0.05A, the display error
will be large.
Small current within 10-40mA are not able to be displayed.
Can be manually adjusted if you need a higher accuracy.
It is recommended to adjust when output current is higher
than 1A
7. Power display: 0.00W-15.0W
8. Over-temperature protection: Yes.
When the temperature of the power device is higher than
100℃, it will trigger -OT- protection. After reduce the load
power, press ON/OFF button.
If the power is within 10W for long-term use, normally it
won't enter –OT- protection. When input current is higher
than 3A for long term use, it may enter over-temperature
protection even though the power doesn't reach 15W.
