Description
WattNode® Wide-Range Meter for Modbus
- The new WND-WR-MB provides over fifty electrical measurements over a Modbus RTU RS-485 network
- Designed as a universal line-powered meter, it works on any utility service from 100 to 600 Vac, single or three-phase, wye, or delta
- The WND-WR-MB has the same dimensions as its WattNode Modbus predecessor but its expanded register map provides many unique features not previously offered in the submetering market
- New registers include fast power for export limiting, registers to correct wiring errors remotely, potential transformer ratio for 4160 Vac and higher utility services, and SunSpec compliance
- Standard Features
- Measures 100 to 600 Vac single-phase or three-phase, wye or delta
- Line powered from 100 to 600 Vac, line-neutral or line-line
- Correct wiring errors remotely
- Change a CT's polarity
- Change a CT to a different line voltage
- PT ratio register for use with potential transformers
- Current transformer disconnect detection
- Modbus RTU, RS-485
- For use with safe low voltage (0.333 Vac) CTs to 6000 amps
- Fast power feature for export limiting applications
- Nine baud rates from 1.2K up to 115K
- SunSpec compliant register list
- Revenue Grade Accuracy
- Meets ANSI C12.1-2014 & ANSI C12.20-2015
- Class 0.5 when used with Class 0.2 CTs
