Physical Dimensions and Rack Mounting
This power supply measures 230 mm in height, 27 mm in width, and 210 mm in depth. Its rugged enclosure weighs approximately 1.5 kg. You can mount the unit in the first slot of the SIMATIC S5 rack. The module locks securely with the built-in retention mechanism.
Connector Interface and Field Wiring
The 6EW1380-4AA features a 3-position terminal block for AC input connections. A separate connector handles all DC output terminations. Each terminal accepts wire sizes from 1.0 mm² to 4.0 mm². The unit includes a ground terminal for functional earth connection.
Protection Features and Safety Systems
This power supply incorporates over-voltage protection on all output channels. It also includes over-current limiting with automatic recovery. A thermal shutdown circuit protects against excessive internal temperatures. The module meets UL and VDE safety standards for industrial equipment.
Status Indication and Monitoring
A green LED indicates normal operation and correct output voltage. A red LED illuminates when the unit enters protection mode. The module provides a DC OK relay contact for external monitoring. This contact changes state when the output falls below 90%.
Application Scenarios and System Integration
This power supply suits SIMATIC S5-115U and S5-135U systems. It works with both single-rack and multi-rack configurations. The unit supports hot-swapping for maintenance without system shutdown. You can use it as a primary power source in any S5 installation.
