EB0510(D)

DB-E91-101A DB-E91-101C

MODEL|FXZ

this is a Main Control PCB (Printed Circuit Board) typically found in high-end HVAC systems, specifically Inverter Air Conditioners (likely Daikin or a similar brand based on the “EB0510(B)” and “MODEL FXZ”

Here is a detailed breakdown of the components and sections visible:

1. Power Supply Section (Bottom)

This area handles the incoming AC power and converts it into usable DC voltages for the board.

• Fuse: A glass tube fuse (bottom left) provides overcurrent protection.
• Inductor/Choke: The large copper coil wrapped around a ferrite core helps with EMI filtering and power factor correction
