Features: 
High quality DC regulated power supply whose output voltage is continuously adjustable from 0 to 30V. 
Including a circuit to limit output current which enables output current to be continuously adjustable from 2mA to 3A. 
Provide current limiting, LED display, over load and short circuit protection. 
Easy to install and maintain. 

Note: 
Please install the resistances and diodes according to PCB diagram. Make sure resistance values, diode models and installation direction are correct. 
Please install other components from small to large, low to high. 
The picture of testing process is just for reference, pls in kind prevail!
