• PN: SA801F
• Brand: ABB
• Series: Freelance / AC800F Distributed Control System
• Type: Rack Power Supply Module

• Function: Installed in the leftmost P slot of AC800F base unit, converts 115-230V AC mains into stable 3.3VDC and 5VDC power, supplies power to rack CPU, communication and all I/O modules. It sends power-fail alarm signal when mains voltage drops, supporting safe shutdown of control programs to avoid data loss and system crash
