Description
The WMC-PM is a modular metering card designed for seamless integration into the WattsOn-MCM platform, enabling flexible and granular power and energy monitoring across multiple circuits
- Each WMC-PM module delivers high-accuracy electrical measurement for up to three channels and supports a variety of CT (current transformer) input types to match diverse installation environments
- FEATURES
- Three-channel measurement per module
- Supports mA-based, mV-based, or Rogowski coil (RC) inputs
- Accuracy of 0.1% for current, and 0.2% for power/energy
- Per-channel configuration of CT ratios, voltage/current mappings, and channel naming
- Virtual metering allows creation of calculated data points via embedded math functions and scripting across all channels and inputs
- USE CASES & BENEFIT
- Modular system growth: Start small and expand as monitoring needs grow, without full re-deployment
- Circuit-level visibility: Enables detailed energy profiling for sub-systems, equipment, or tenants
- Protocol flexibility: Integrates into modern building automation, SCADA, or energy management systems via standard protocols (Modbus, BACnet, HTTP, MQTT)
- Custom analytics: Use virtual points for on-the-fly calculations (e.g. summing loads, combining circuits) without external software
- APPLICATIONS
- Commercial buildings, data centers, and campuses
- Renewable energy systems and microgrids
- Industrial installations and manufacturing plants
- Tenant energy sub-metering
