Description
FANUC A16B-2203-0640 PCB / Main Board (αi Series)
The A16B-2203-0640 from FANUC is an internal power wiring PCB / main board used in FANUC αi series CNC drive systems. It is not a standalone module but a critical internal circuit board typically installed inside power supply units.
Detailed Product Description
The FANUC A16B-2203-0640 is a specialized power wiring printed circuit board (PCB) designed for integration within FANUC αi series power supply modules. This board manages internal power distribution, signal routing, and electrical connectivity between major components of the drive system.
It is commonly found in PSMi (Power Supply Module integrated) units, particularly around the 5.5 kW class, where it plays a key role in ensuring stable electrical flow and system reliability.
Due to its role as an internal component, the A16B-2203-0640 is typically supplied as part of a complete module rather than sold separately.
