4.3 සවි කිරීම

The power supply features screw fixing holes for secure mounting on a wall or shelf. Ensure the mounting location allows for proper ventilation.

5. මෙහෙයුම් උපදෙස්

5.1 බලය සක්රිය / අක්රිය

Once all connections are secure and the input voltage is correctly selected, connect the power supply to the AC mains. The unit will power on automatically. Disconnect from AC mains to power off.

5.2 ප්‍රතිදාන වෙළුමtagඊ ගැලපීම

The output DC voltage can be finely adjusted using the 'ADJ' potentiometer located on the terminal block. Use a small screwdriver to carefully turn the potentiometer clockwise to increase voltage or counter-clockwise to decrease it. Monitor the output voltage with a multimeter during adjustment.
