Description
Continental Control Systems, a leader in accurate, reliable, and economical measurement power and energy, has designed a new power meter that is easy to customize for high-volume OEM applications
- The WattNode Power Meter is a bidirectional (production and consumption) networked energy meter offering energy measurement parameters such as energy (kW), power (kWh), voltage, current, demand, kVAR, kVARh, power factor, frequency, etc.
- These electrical measurements are communicated using the Modbus RTU communication protocol over RS-485
- Revenue-grade accuracy is obtainable using the CCS Accu-CT® family of current transformers, (Class 0.6 or Class 0.3 accuracy), otherwise the meter module utilizes any externally mounted or PCB mounted 0.333 Vac current transformers
- Available factory configured for single or three phase application, the meter is externally (instrument) powered from 12 to 24 Vac or 6 to 24 Vdc.
- New Features
- Correction of CT polarity remotely
- Correction of line voltage connection remotely
- PT ratio register for use with potential transformers
- Current transformer disconnect detection
- SunSpec compliant register list
- Standard Features
- Modbus RTU, RS-485; isolated communication
- 100+ Modbus registers
- For use with safe low voltage (0.333 Vac) or 40mA CTs
- Fast power feature for rapid demand response
- Current Measurement: 5 to 6000 amps
- ANSI C12.20 with Class 0.2 current transformers
- External Power Supply: 12 to 24 Vac isolated or 6 to 24 Vdc
- Single or three phase, wye or delta configuration
- UL and cUL Listed, CE, RoHS compliant
- 5 year warranty
- Electrical Measurements
- True RMS Power: watts, per phase and sum
- Reactive Power: VARs, per phase and sum
- Power Factor: Phase, per phase and average
- True RMS Energy: kWh per phase and sum
- Reactive Energy: VAR hours, sum
- Frequency
- RMS voltage per phase and average
- RMS current per phase and average
- Demand and peak demand
- Modbus Communication
- Protocol: Modbus RTU (binary)
- Baud Rates: selectable from 9,600 to 115,200
- Half Duplex: (two-wire plus common)
- New Socomec Part Number: 48710400
- Baud Rates:
- 1.2K = 1,200
- 2.4K = 2,400
- 4.8K = 4,800
- 9.6K = 9,600
- 19K = 19,200 (Default Setting)
- 38K = 38,400
- 57K = 57,600
- 76K = 76,800
- 115K = 115,200
- Default Modbus Slave address: 1 (AD=1). Call Aim if you want a different initial address
- Address and Baud Rates can be change via software once the meter is attached to the Modbus RTU network
- If the meter is ordered with non-default address or baud rate options, they will appear on the label
- Once in the field, the communication settings can only be changed using Modbus messages to write new settings
- The communication settings may be changed using the Modbus registers BaudRate, Address, ParityMode, ModbusMode, SerialNumberKey, and NewAddress
- Optional Suggested Power Supply
- HDR-30-24 Input: 85~264 Vac, 120~370 Vdc; Output: 24 Vdc, 36 W
- XDR-75-24LA Input: 85~305 Vac; Output: 24 Vdc, 75 W
