Industrial Application Scenarios

Central Office DC Power Distribution:
Telecommunications central offices rely on DC power systems to maintain continuous operation of switching equipment, transmission gear, and network infrastructure during utility outages. The EMU10 provides operators with centralized visibility into rectifier module status, battery voltage trends, load current distribution, and system ground faults—all accessible via the 7-inch touchscreen without requiring separate monitoring computers. Multi-language support (Chinese/English switching) accommodates international carrier deployments and multilingual operations teams managing geographically distributed facilities.

Utility Substation Control Power Monitoring:
Protective relays, SCADA remote terminal units, circuit breaker controls, and substation automation equipment depend on reliable DC control power to function correctly during grid disturbances. The EMU10's <2 millisecond response time enables rapid detection of voltage sags, transients, and ground faults that could compromise protective relay operation—preventing misoperations that lead to cascading outages. Reserved IEC61850 interface support positions substations for future integration with intelligent electronic devices (IEDs) and digital substation architectures mandated by smart grid modernization initiatives.

Data Center Infrastructure Power Management:
Hyperscale data centers and colocation facilities distribute DC power to servers, storage arrays, and network switches to improve energy efficiency and reduce conversion losses. The EMU10 integrates with building management systems (BMS) and data center infrastructure management (DCIM) platforms via Ethernet connectivity, providing facility managers with real-time power quality metrics, historical trend data for capacity planning, and alarm notifications when voltage deviations threaten IT equipment reliability or violate service level agreements (SLAs).

Industrial UPS & Battery Charging Supervision:
Manufacturing facilities, hospitals, and critical infrastructure installations depend on uninterruptible power supply (UPS) systems and battery backup to maintain operations during utility failures. The EMU10 monitors battery charging voltage and current in real time, ensuring batteries remain within optimal charging parameters that maximize cycle life and prevent premature failures. Alarm notifications alert maintenance personnel to charging anomalies—such as overcharging, undercharging, or cell imbalances—requiring immediate corrective action before backup capacity degrades.

Railway Signaling & Train Control Power Systems:
Railway signaling equipment, interlocking systems, and automatic train protection (ATP) infrastructure require uninterrupted DC power to ensure safe train operations. The EMU10's rugged IP65 enclosure and M12 connector withstand the vibration, temperature extremes, and environmental contaminants encountered in trackside installations and signal equipment rooms. Precise time stamping via iRIG-B synchronization enables correlation of power system events with train movements and signaling actions during incident investigations and regulatory compliance audits.

Technical Specifications & Selection Guide

Selection Criteria: Choose the EMU10 when your application requires touchscreen local display, multi-protocol communication, and operation in temperature extremes or dusty/wet environments. For systems requiring only remote monitoring without local display, consider alternative monitoring modules with lower cost and smaller footprint. Consult our application engineers to determine optimal monitoring architecture for multi-site deployments or systems with more than 20 rectifier modules.

Extended Capabilities & IoT Integration

✓ Web-Based Remote Access: Built-in web server enables monitoring via standard browsers from any location with network connectivity—eliminating proprietary software licensing costs and enabling smartphone/tablet access for on-call personnel responding to after-hours alarms.

✓ Historical Data Logging & Trend Analysis: Internal memory stores voltage, current, and alarm event data with configurable sampling intervals, supporting capacity planning studies, battery discharge testing, and regulatory compliance documentation for critical infrastructure facilities.

✓ Customizable Alarm Thresholds: Configure voltage high/low limits, current overload thresholds, and ground fault sensitivity to match specific equipment requirements and operating policies—reducing nuisance alarms while ensuring genuine faults trigger immediate notifications.

✓ Multi-Language User Interface: Chinese/English language switching accommodates international deployments and multilingual operations teams, with additional language packs available through firmware updates for European, Middle Eastern, and Asia-Pacific markets.

✓ SNMP Trap Integration: Generate SNMP traps for integration with enterprise network management systems (NMS) such as HP OpenView, IBM Tivoli, and SolarWinds—consolidating power system alarms with IT infrastructure monitoring for unified operations center dashboards.
