Blue Star Vrf Dvrf Ductable Indoor Pcb With Smps Pcb Board Blue Star VRF Air Conditioner Control Panel PCB with SMPS Power Supply

this is a Blue star VRF ductable Indoor PCB Main Logic Board (Left): This green PCB is the “brain.” It contains the microcontroller, status LEDs, and communication ports. You’ll notice connectors for sensors (likely temperature or airflow) and the user interface panel.

Power Supply Unit (Top Right): This smaller board handles voltage regulation. It likely converts high-voltage AC from your mains into the low-voltage DC (5V or 12V) needed to run the logic board.

Terminal Block (Bottom Right): This is where the heavy lifting happens. The “L” (Live) and “N” (Neutral) markings indicate where your primary power enters and where the system distributes power to fans

Grounding Point: Note the yellow circular sticker at the bottom—that’s your chassis ground. Safety first!
