The Siemens 6EP1333-2AA01 is a SITOP PSU100M power supply delivering a SELV 24 VDC output rated at 5 A continuous, with a rated range of 0 to 6 A that holds up to +45 °C before derating is needed. It accepts dual AC input ranges — 85 to 132 VAC or 170 to 264 VAC — at 47 to 63 Hz, making it usable across 120 V and 230 V line supplies worldwide. The unit snaps onto a DIN rail per EN 60715 (35×7.5/15 profile) and is protected to IP20, so it belongs in a clean, dry enclosure, not a washdown zone.
The 5 A rated output (6 A up to +45 °C) is the continuous current you can draw from the 24 VDC rail. If your load pulls more than 6 A, or ambient temperature exceeds 45 °C, you need to derate or step up to a higher-output sibling. The internal fuse is a T 3.15 A/250 V type, not user-accessible, so overcurrent protection on the output side must be handled by an external miniature circuit breaker — Siemens recommends a 6 A characteristic C breaker in the feeder. The I²t value of 0.8 A²·s tells you the energy let-through during a short; keep that in mind when coordinating downstream protection.
This unit carries cULus listing under UL 508 and CSA C22.2 No. 107.1 (File E197259), plus cCSAus per UL 60950-1 and CSA C22.2 No. 60950-1. It also holds CE and EAC marks, and is DNV GL approved for marine applications. The output is galvanically isolated with safety extra-low voltage (SELV) per EN 60950-1 and EN 50178. No ATEX, IECEx, FM, or UL hazloc approval — not rated for explosive atmospheres.
Output wiring: L+ and M each have two screw terminals for the same wire range, allowing daisy-chaining to multiple loads without a separate terminal block. The selector switch on the device sets the output voltage. Storage and transport temperature range is -40 to +85 °C; operating range is 0 to +60 °C with natural convection — no forced cooling required in most panel environments.
