Multi-Gain™ Sensing Provides Superior Accuracy The Nexus® 1450 meter utilizes EIG’s latest measurement-sensing technology - Multi-Gain™. Multi-Gain™ technology uses two sensors on the current inputs - a high gain sensor and a lower gain sensor. Each sensor simultaneously measures the current signal coming from the external current transformers. The meter’s intelligent processing looks at the signal level and determines the optimal sensing circuit for the highest accuracy measurement. With this technique, the meter has 0.06% accuracy throughout an extended measurement range, which is a defining trait of Nexus® Series meters. The meter’s standard pickup range starts as low as 1 mA, and high accuracy is attained at 25 mA. Multi-Gain™ metrology allows the same meter to be used on both 5 A secondary and 1 A secondary CTs. The meter should maintain high accuracy measurement throughout its installed life. Refer to the accuracy chart on the next page, for details. With 6 simultaneously operating communication ports, the meter is a communication hub to multiple software systems. The Nexus® 1450 meter has 4 serial ports that speak Modbus and DNP 3.0 protocols. It also has two independent Ethernet ports, consisting of a 10/100BaseT copper RJ45 connector and an ST Terminated 100Base FX Fiber Optic Ethernet port. Each Ethernet port has a unique IP address. Through the meter's 6 ports, a user is able to communicate to multiple computer-based systems, providing data to entities throughout an enterprise. The meter also excels at measuring power quality, including waveform recording and IEC 61000-4-7, IEC 61000-4-15, and IEC 61000-4-30 Class A compliance. The Nexus® 1450 meter lets you look at the reliability of the electrical power circuit to determine causes of faults, voltage surges and sags, and harmonics.
