Product Description

The Siemens SITOP PSU300S 6EP1434-2BA20 is a high-performance switched mode DIN Rail Power Supply designed to convert three-phase alternating current (AC) into a stable direct current (DC) output for demanding industrial automation and control applications. Engineered for environments requiring high availability and reliability, it delivers up to 240W of regulated DC power, covering a wide range of operational needs in industrial machinery, process control panels, and laboratory equipment.

This power supply accepts a broad input voltage range of 340V to 550V AC in three-phase configuration, making it compatible with modern industrial grids across diverse geographies. Its DC output is precisely regulated between 24V and 28V, supporting up to 10A of continuous load. Advanced design features include a static load regulation of 0.15% and dynamic regulation of 3%, ensuring voltage consistency that critical electronics depend upon.

The SITOP PSU300S is encased in a robust IP20 enclosure for enhanced user and equipment safety in panel installations. Its compact footprint (height 125mm, width 70mm, depth 120mm) simplifies integration into confined DIN rail spaces, optimizing enclosure real estate. High conversion efficiency (91%) reduces energy consumption, contributing to lower operational costs and reduced heat generation, which is particularly beneficial in densely packed electrical cabinets.

Operational resilience is ensured through an extended temperature range from -25°C to +70°C, adapting seamlessly to both hot and cold industrial sites. The power supply includes critical safety and monitoring features such as DC-OK remote signaling, green operational LED indication, and electrical isolation between input and output, safeguarding sensitive downstream equipment from faults and surges. The long mean time before failure (MTBF) of over 500,000 hours underlines Siemens' quality commitment for uninterrupted service.

Rigorous compliance with international standards (UL, CSA, CE, UKCA, EAC) makes this unit ready for global deployment and cross-border projects. Applications encompass factory automation, process engineering, HVAC control, laboratory and test benches, and infrastructure lighting networks - wherever reliable DC power is vital.

The Siemens SITOP PSU300S comes with mounting flexibility, robust protection features, and high efficiency - making it an ideal choice for demanding professional, commercial, and industrial use cases.
