The A20B-2101-0355 power supply PCB from FANUC serves as a critical component in spindle management systems. This multi-layer control board operates at an input voltage between 220V and 240V AC. Its design is intended to function optimally within ambient temperatures that range from 0°C to 55°C, offering robustness across various operational conditions.

This PCB is notably integrated into spinning modules and facilitates communication via several protocols, including CAN Bus, Profibus, CC-Link, and EtherCAT, depending on the specific module configuration. It features a lightweight design, weighing between 0.6 kg and 0.8 kg, which enhances its integration versatility.

The embedded multi-pin PCB interface streamlines connections while ensuring compatibility with ALPHA i Power Supply systems and aiSV servo drives. This enables the board to effectively manage spindle commands. The cooling method utilized by this PCB is passive, relying on module-dependent airflow, allowing it to maintain optimal operating conditions without additional active cooling solutions.

Its capabilities extend to supporting power ranges from 2kW to 100kW for spindle modules, and it is designed to function within high voltage classes, compatible with 200V and 400V HV systems.
