Light Commercial Kilowatt Hour Meter, 3-Phase 120-277V, Watt Hour Meter
Light Commercial Kilowatt Hour Meter, 3-Phase, 120-277 Volt Auto-Ranging Power Supply Suitable for Both 277/480V, 4W, WYE and 240/480V 4-Wire Delta Services, 7 Jaw. Active Energy and Digital Multiplication Measurement, Non-Volatile Memory, 9-Digit LCD, Display Scroll Sequence Programmable (Factory or End User).
The FOCUS® AX Polyphase meter provides a cost-efficient alternative for light
commercial metering applications that do not require all of the functionality of the S4e meter. As an addition to the FOCUS family of meters, the AX Polyphase brings the same proven solid-state performance utilities have come to expect from FOCUS meters, in an economical and AMI-ready platform for commercial and industrial applications.
A single circuit board design, mounted at the front of the meter allows room for modular AMI communications or a KYZ output board. Highly accurate load performance and the use of field-proven Digital Multiplication Measurement Technique ensure reliability and dependability during the entire life of the meter.
The FOCUS AX Polyphase meter is available for both self-contained and transformer-rated meter forms and includes the ASIC, nonvolatile memory, selectable metrics, flexible display functionality, an optional KYZ output, configuration port, and a customer program option.
