The Panasonic AFP7PSA2 is the FP7-series power supply module that converts 100 ~ 240 VAC line input to a regulated 24 VDC bus at 1.8 A — enough to power the CPU rack and a modest I/O slice without an external brick.
The 1.8 A output capacity at 24 VDC sets the total current available for the FP7 backplane and any expansion modules. If your I/O count or specialty modules (motion, counter, analog) draw more than that, you need a second power supply or a higher-rated unit — the AFP7PSA2 is sized for a compact rack, not a full chassis. DIN rail mounting and screw-terminal wiring match standard panel layout practice — the module clips onto the rail and accepts ferrule-terminated or solid conductors up to the terminal rating. Operating range is 0°C to 55°C, typical for IP20 cabinet environments.
