Key Features and Benefits
The EMC400-EPWS stands out for its ultra-fast switchover time of less than 5 milliseconds, ensuring that connected devices receive continuous power without disruption during main supply failures. This rapid response is critical for sensitive control systems, where even brief power interruptions can cause process errors or equipment damage.
A core advantage of the
EMC400-EPWS is its intelligent battery management system, which optimizes charging cycles and monitors cell health to extend battery life. The hot-swappable lithium-ion batteries allow for replacement without powering down the module, ensuring uninterrupted protection during maintenance—ideal for 24/7 operations where system shutdowns are not feasible.

The module’s flexible runtime configuration enables users to select battery capacities based on specific needs, from 15-minute backups for transient outages to 60-minute solutions for extended disruptions. This customization helps balance cost and protection, ensuring optimal performance for each application.
Advanced monitoring and communication features set the EMC400-EPWS apart, including LED status indicators and optional Modbus RTU/Ethernet connectivity for remote monitoring. Users can track battery level, input/output voltage, and runtime remaining, while predictive alerts notify maintenance teams of low battery capacity or potential faults, enabling proactive service.
The EMC400-EPWS also includes comprehensive protection mechanisms, such as overload and short circuit safeguards, which prevent damage to both the module and connected equipment. Its wide input voltage range (110-240V AC) ensures compatibility with global power systems, simplifying international deployments.
