Electro Industries’ Nexus® 1450 meter is a powerful power quality meter that provides accurate electrical energy measurements. It offers advanced capabilities for power quality analysis and determining electrical power reliability. The meter is a transducer base with a separate display. The transducer base retrofits to existing Electro Industries’ Nexus® 1250 and 1252 meters. The Nexus® 1450 power quality meter is ideal for existing switchboard panels since it can be installed without cutting panel doors. The separate display mounts into existing analog meter knockouts.

Multi-Gain™ Sensing Provides Superior Accuracy
EIG’s Latest Measurement Sensing Technology
- Patented technology provides 0.06% energy accuracy throughout extended measurement range, from start up to full scale
- Multi-Gain™ technology uses two sensors on the current inputs to determine the optimal sensing circuit for the highest accuracy measurement
- Standard pickup range starts as low as 1 mA – high accuracy is attained at 25 mA
- Multi-Gain™ metrology enables one meter to be used on both 5 A and 1 A secondary CTs
- The meter should maintain high accuracy measurement throughout its installed life
- The power quality meter meets ANSI C12.20 0.1 and IEC 62053-22 0.2S accuracy classes

IEC 61850 GOOSE Messaging and Distributed Fault Recording
GOOSE Cross Trigger Support
- Unique distributed disturbance recording analysis improves substation reliability
- Up to 16 user-programmed conditions to trigger system-wide waveform capture
- Enables analysis of power quality events across the power system
Direct Retrofit with Advanced Remote Displays
Replace Older Meters without Panel Modification or Recertification
- Transducer/remote display direct retrofit to older Nexus® 1252 meters makes installation cost effective
- Remote displays retrofit to ANSI cutouts, so the power quality meter can be mounted in back of panel
- P70N color touchscreen LCD display offers multiple pre-configured screens.
- P40N+ LED display can act as a master to P41N+ Ampere and P43N+ Power displays, providing 3 panel displays on one connection powered by the meter. This is ideal for substation and power plant applications.
