Product Details
The Northern Design Modular metering system is designed for applications where multiple meters are required on-site. It uses a Single voltage reference and bespoke voltage-output Current transducers that can be clipped round live conductors without producing hazardous voltages on the secondary (as is the case with conventional 5A Current Transformers).
Modules: Up to 10 additional Slave Modules available for the Multicube (Modbus RTU or TCP/IP, M-bus and Pulse output communications)
Parameters: kWh, kVARh, kW, kVA, kvar, V, A, PF & Hz with an accuracy better than Class 1. All parameters are available via the display or remotely via Modbus/TCP
Current Transducers (0.333V): Any 0.333V output Transducers
Installation: Left-hand side (Communications - Maximum 1 per Master) and Right-hand side (Slaves - Maximum 10 Per Master)
