Siemens Aktiengesellschaft 6EP1333-2BA20 Power Supply

Siemens Aktiengesellschaft's SITOP PSU100S 24 VDC power supply, model 6EP1333-2BA20, is a compact DIN-rail-mounted, stabilized supply for industrial control panels. It accepts a single‑phase AC input of 120/230 VAC and delivers a regulated 24 V DC output at up to 5 A (approximately 120 W). The unit is IP20-rated, designed for DIN-rail installation, and intended to power logic circuits, PLCs, sensors, and actuators in automated systems. Efficiency is typically around 88% at rated load, with a derating of about 5% per Kelvin at higher ambient temperatures up to the device’s operating limits, and protection features include electronic shutdown with automatic restart, current limiting for short circuits, and robust overvoltage protection, along with EN 60950-1 safety compliance. The 6EP1333-2BA20 variant belongs to the SITOP PSU100S family, widely used to supply 24 V DC for Siemens SIMATIC automation components in control cabinets, offering reliable performance in typical industrial environments.
