Product Description

The Siemens 6EP1331-5BA00 is the most compact member of the SITOP PSU100C family — an entry-level stabilized power supply delivering 24 V DC at 0.6 A in a housing just 22.5 mm wide, making it the go-to choice for powering small PLCs, HMIs, and isolated sensor loops in tightly packed control panels.

Small Size, Full Protection

22.5 mm width saves DIN rail space — the narrowest SITOP power supply available
NEC Class 2 certified per UL 1310 — output is inherently energy-limited, simplifying field wiring compliance
Electronic short-circuit protection with automatic restart — no fuse replacement
82% efficiency at 14 W with only 2.6 W power loss, manageable without forced cooling
