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.
