WattNode® Wide-Range Meter for Modbus – Advanced Energy Monitoring
The WND-WR-MB WattNode® Wide-Range Meter is a high-precision energy meter that provides over fifty electrical measurements via a Modbus RTU RS-485 network. Designed for universal compatibility, it operates on 100 to 600 Vac utility services in single-phase or three-phase, wye, or delta configurations. This line-powered meter is ideal for submetering applications in commercial and industrial environments, offering advanced features for accurate energy tracking and system optimization.
Key Features:
- Wide Voltage Compatibility – Supports 100-600 Vac systems, single or three-phase, wye or delta
- Line-Powered – Operates directly from 100-600 Vac, line-neutral or line-line
- Expanded Register Map – Provides additional features not found in previous WattNode Modbus models
- Remote Error Correction – Adjust wiring errors, change CT polarity, and modify CT voltage settings remotely
- Potential Transformer (PT) Support – Includes a PT ratio register for services 4160 Vac and higher
- Current Transformer (CT) Compatibility – Works with safe low-voltage (0.333 Vac) CTs up to 6000 amps
- Current Transformer Disconnect Detection – Detects when CTs are disconnected to prevent measurement errors
- Fast Power Measurement – Supports export limiting applications for renewable energy systems
- Modbus RTU Communication – Utilizes RS-485 with nine selectable baud rates from 1.2K to 115K
- SunSpec Compliance – Ensures compatibility with industry-standard monitoring platforms
- Revenue-Grade Accuracy – Meets ANSI C12.1-2014 & ANSI C12.20-2015 Class 0.5 standards when used with Class 0.2 CTs
The WND-WR-MB WattNode® Wide-Range Meter is a powerful solution for energy monitoring, providing reliable, real-time data for energy management, submetering, and compliance applications.
