Siemens 6EP1331-5BA10 DIN Rail Power Supply Module

Siemens 6EP1331-5BA10 SITOP PSU100C is a compact DIN-rail mounted power supply that delivers a stable 24 V DC output for industrial control panels. Designed for single‑phase mains, it accepts 120–230 V AC (110–300 V DC) and provides 24 V DC at up to 1.3 A, roughly 31 W of continuous output. This variant is part of the SITOP PSU100C family, which offers a reliable, regulated supply for logic circuits, PLCs, sensors, and small actuators in automation environments. The module is intended for DIN‑rail installation, allowing straightforward integration into standard control cabinets and ensuring a consistent 24 V rail across distributed automation components. Typical applications include powering Siemens S7 PLCs, I/O modules, and peripheral devices in machine and line automation, where a compact, robust DC supply is needed to keep control systems energized through production cycles. The 6EP1331-5BA10 designation corresponds to the 24 V/1.3 A version, and the unit carries common industry approvals such as CE and UL/cUL (CSA) for use in certified installations.
