How Moxa Empowers Reliable Power Monitoring in Modern Data Centers

Overview

As data centers scale to meet the demands of cloud computing, AI, and real-time services, reliable power monitoring becomes a critical pillar of operational resilience. Electrical Power Monitoring Systems (EPMS) provide visibility into power consumption, quality, and distribution, enabling proactive management and rapid fault response.
Moxa plays a vital role in this space by offering robust, industrial-grade connectivity solutions that bridge legacy OT devices and modern EPMS platforms. This case study highlights how Moxa’s technologies are used to build scalable, secure, and efficient EPMS infrastructure in leading data centers around the world.

Challenges

Data centers face increasingly complex challenges when deploying or upgrading EPMS infrastructure:

• Integration of legacy Modbus serial devices into modern Ethernet-based systems
• Harsh operating environments near power equipment (EMI, temperature extremes)
• Security risks from connecting critical power systems to networked platforms
• Demand for scalable and manageable connectivity across thousands of devices
• The need for real-time monitoring to support uptime and predictive maintenance

Solution: Moxa’s Industrial Connectivity Framework

To address these challenges, Moxa offers a full portfolio of connectivity hardware and management tools tailored for industrial and power-critical environments.

Key Products Used:

• NPort Serial Device Servers – Connect legacy RS-232/422/485 power meters to Ethernet
• MGate Protocol Gateways – Convert Modbus RTU/ASCII to Modbus TCP for unified data integration
• EDS & PT Series Ethernet Switches – Ensure reliable, redundant communication across the EPMS network
• ioLogik Remote I/O Modules – Collect data from digital/analog sensors and equipment without native network interfaces
• MXview One – Centralized network management for visibility, configuration, and security compliance

All products are hardened for industrial conditions, support advanced security protocols, and are designed for interoperability across both legacy and modern systems.
