Siemens 6ES5930-7AA11 Power Supply Module for SIMATIC S5

The Siemens 6ES5930-7AA11 provides stable DC power to SIMATIC S5 controller racks. You can install this module into any standard S5 power slot. It converts 115 V AC or 230 V AC into regulated 24 V DC output. This unit supports CPUs, I/O modules, and communication processors reliably.

Technical Specifications and Hardware Configuration

This power supply module measures 233 mm in height. Its width reaches 36 mm, and the depth equals 182 mm. The Siemens 6ES5930-7AA11 weighs approximately 0.95 kilograms. A single internal PCB carries all rectification, filtering, and regulation circuits. The module contains three electrolytic capacitors for bulk energy storage. These capacitors provide 25 milliseconds of hold-up time during input dips. One 3-pin screw terminal block accepts AC input wiring. A dedicated 5-pin connector delivers DC output to the backplane.

Electrical Ratings and Performance Characteristics

The Siemens 6ES5930-7AA11 accepts input voltages from 85 V AC to 264 V AC. It operates at line frequencies of 47 Hz to 63 Hz automatically. This module delivers a nominal output of 24 V DC at 4.5 A continuously. Output ripple stays below 40 mV peak-to-peak at full load. Efficiency reaches 83 percent under typical operating conditions. Consequently, this unit generates moderate heat inside the cabinet. Overvoltage protection clamps the output at 28 V DC maximum. Short-circuit protection safely shuts down the output during wiring faults.

Installation and Operational Guidelines

You must slide this module into the leftmost slot of the S5 rack. Transitioning to wiring, use 1.5 mm² stranded wire for the AC terminals. A green front LED indicates normal output voltage presence. The module requires 40 mm of free space above and below for airflow. For safety, disconnect mains power before removing the unit. The operating temperature range sits between 0°C and 55°C reliably.
