The new Nexus 1262 combines EIG's latest performance enhancing technology into an affordable socket based meter that meets and exceeds the needs of virtually all utility or industrial metering and analysis applications. This unit specifically meets the sophisticated standards required by utility companies and deregulated power providers for advanced revenue metering, control and power quality.
Standard features in the 1262 include a fully adjustable graphical backlit LCD display (easily read in all lighting conditions), compact low profile design, unrivaled accuracy measurements, multiple communication protocols and user definable control options previously unattainable.
Generation Plants
The Nexus 1262 utilizes fixed, sliding, thermal and predictive demand integration intervals allowing for improved load management. PLC functionality allows for load curtailment applications based on programmable logical configurations.
Substation Monitoring
The Nexus 1262 with its standard features is the ideal substation-metering device measuring every aspect of power and providing real time revenue quantities. This data can be monitored locally or remotely via direct serial communication, optional on-board Ethernet or onboard modem.
Metering for Critical Customers
For customers concerned with electrical costs, put their minds at rest with 0.08% watt/hour accuracy, historical data logging, load profiling for load management, power quality event recording and analysis tools.
