Nexus® 1450 Cyber Secure Power Quality Meter with Multiport Communication
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 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 meter meets ANSI C12.20 0.1 and IEC 62053-22 0.2S accuracy classes.
