Industrial Applications & Use Cases

This SITOP power supply excels in factory automation systems powering S7-300/400 PLCs, distributed I/O networks, and HMI panels. Common deployments include packaging lines requiring stable 24V DC for pneumatic valve manifolds, conveyor control systems with multiple motor starters, and process control installations with analog transmitters. The unit's wide input voltage tolerance makes it suitable for facilities with unstable grid power or generator-backed systems.

Engineered Solutions for Power Reliability

Advanced features include automatic restart after overload conditions, short-circuit protection with automatic recovery, and overvoltage shutdown to protect connected equipment. The adjustable output voltage allows compensation for voltage drops in long cable runs—critical for large installations. Built-in EMC filtering reduces electrical noise injection into sensitive control circuits, while the fanless convection cooling design eliminates maintenance requirements and acoustic emissions.

Installation & System Integration

Quick-connect spring-loaded terminals accept 0.5-6mm² conductors without tools, reducing installation time. Front-mounted LED indicators display AC OK, DC OK, and overload status for rapid diagnostics. Parallel operation capability enables N+1 redundancy configurations using SITOP diode modules. The compact 3-module width (160mm) conserves valuable panel space while delivering high power density of 125W per module width.

Frequently Asked Questions

Q: Can this power supply operate on 110V AC systems?
A: Yes, the wide input range (120/230V AC ±15%) accommodates 110V systems commonly found in North American industrial facilities.

Q: What is the recommended fuse size for input protection?
A: Use a 10A slow-blow fuse for 230V AC input or 16A for 120V AC input, per Siemens installation guidelines.

Q: Does this unit support redundant power configurations?
A: Yes, when combined with SITOP diode modules (6EP1961-2BA00), multiple units can be paralleled for N+1 redundancy.

Q: What is the expected service life?
A: With proper ventilation and ambient temperatures below 40°C, expect >100,000 hours MTBF based on Siemens reliability data.
