Description
Description
The Siemens 6EW1380-4AB01 is a regulated power supply module designed for the Simatic S5-090, S5-095, and S5-100 controller systems. This unit provides stabilized 24 VDC output from single-phase AC line inputs, ensuring reliable operation for processing logic units, communication buses, and field-side sensors. It is engineered to isolate downstream logic circuits from line voltage surges and frequency fluctuations, featuring integrated overcurrent protection to maintain system stability during load shifts.
Features
- Switched-mode power converter with dual-range input configuration (115/230 VAC).
- Galvanic separation between primary high-voltage input and secondary 24 VDC output.
- Integrated thermal overload protection and short-circuit current limiting.
- 10 A continuous output capacity.
- Status monitoring capabilities for integration with PLC backplane diagnostics.
- Natural convection cooling via slotted aluminum chassis.
Applications
This power supply is utilized in industrial automation environments including material handling systems, automotive assembly lines, and water utility networks where consistent 24 VDC power is required for S5 series peripheral stations.

Installation Guidelines
-
Voltage Selection: Verify the internal input voltage selection bridge matches the supply voltage (115 VAC or 230 VAC) before applying power to prevent damage.
-
Mounting: Install the module vertically on support frames. Maintain a minimum of 50 mm clearance above and below the unit to ensure adequate convective airflow.
-
Grounding: Connect the primary PE terminal to the cabinet common ground plane using a low-impedance conductor to manage noise transients and leakage currents.
-
Safety: Always disconnect primary power before performing maintenance or wiring changes.
FAQ
Is this power supply compatible with all S5 series controllers?
This module is specifically designed for the Simatic S5-090, S5-095, and S5-100 controller sub-tiers. Please verify your specific rack configuration before installation.
