Output rating and what it means on the line
The Siemens 6EP1331-2BA00 is a Sitop Power AC/DC supply delivering 24 VDC at 2 A continuous, rated for 58 W total output. That 2 A rail is sized for a small control cabinet — think a handful of 24 VDC relays, a compact PLC brick, and a couple of sensors. The input draws between 0.9 and 0.6 A depending on line load, so the upstream breaker doesn't need to be oversized.
