VMP3120-230 Electronic Smart Meter; Class 1.0, 3 Phase, Wh and varh, four quadrant, 230V 120A Direct Connect electricity meter.

VMP3120-230 Current Transformer Operated Smart Meter
The VMP3120-230 smart meter is Class 1.0, 3 phase 4 wire, Wh and varh, four quadrant, 230V 120A direct connect, time interval electronic meter suitable for small to medium commercial and industrial sites such as shops, small factories, and large domestic sites.

The meter provides both an optical port (IEC or ANSI configuration) plus an RS232 port for communications.

The RS232 port also provides power for external modems negating the need for an external supply.


Revenue Billing, Demand-side Management and Demand Response Applications
While ideal for revenue billing activities where 15 or 30 minute time interval data collection is required, the meters can also be remotely configured to provide a real time stream of energy data (e.g. Wh, varh, VAh and PF) with programmable demand periods.

The metered data can then be seamlessly delivered to energy management systems enabling customers, utilities and network companies to interact in real time to undertake demand-side management and demand response activities.
