ALSTOM EP3-E-4-EN Intelligent Switched-Mode Power Supply Module
The ALSTOM EP3-E-4-EN functions as an intelligent switched-mode power supply module. Like the EP3-E-4-A, it converts AC input (85-264V AC) into a stable 24V DC output with a maximum continuous current of 4A. However, it adds an Ethernet interface, which is a key difference. This interface supports standard industrial communication protocols such as Modbus TCP/IP, enabling the module to transmit real-time power data (including input voltage, output current, temperature, and operating status) to the central control system or IIoT platform.

Another notable feature is its enhanced monitoring and diagnostic capabilities. In addition to the protection mechanisms of the EP3-E-4-A (overvoltage, overcurrent, short-circuit, and overtemperature protection), theEP3-E-4-EN can record fault logs, including the time, type, and duration of each fault. This helps maintenance personnel analyze the cause of faults and take preventive measures. Moreover, it has a built-in web server, allowing users to configure and monitor the module through a web browser without the need for special software, simplifying on-site operations.

EP3-E-4-EN
Main features and advantages:
The ALSTOM EP3-E-4-EN offers several unique benefits. The addition of the Ethernet interface enables remote monitoring and management, which is particularly valuable for industrial facilities spread over large areas or with harsh on-site environments. For instance, in a remote mining operation, engineers can monitor the power supply status of the control system from the central office, reducing the need for on-site inspections and improving work efficiency.
The enhanced efficiency (≥91%) further reduces energy consumption, which is in line with the trend of industrial energy conservation and environmental protection. The fault logging function provides valuable data for predictive maintenance, helping to minimize unplanned downtime. The web-based configuration simplifies the setup process, allowing technicians with basic IT knowledge to complete the configuration quickly, reducing the reliance on specialized personnel.
EP3-E-4-EN
Application areas:
The ALSTOM EP3-E-4-EN is widely applicable in various industries. In smart grids, it can supply power to the monitoring equipment of substations and transmit real-time power data to the grid management system, facilitating grid dispatching and fault handling. In data centers, where the stability of power supply to server cabinets is critical, it ensures a stable 24V DC power supply for control modules and monitors the power status in real time to prevent potential power failures.
In pharmaceutical production facilities, which have strict requirements for production process stability, the EP3-E-4-EN provides reliable power to the control systems of production lines. Its network communication capability enables the integration of power data into the production management system, ensuring compliance with relevant regulations through complete data records.
