A1800 ALPHA meter

The A1800 ALPHA® is a world-class, highly accurate, robust, system ready meter that is ideally suited for advanced commercial, industrial, and substation metering applications. With its open communication protocol, the A1800 ALPHA meter can be integrated into any metering system. The A1800 ALPHA meter can be easily upgraded and offers our customers the flexibility to keep pace with their changing metering requirements and business growth.

 

The A1800 ALPHA includes all of the high functionality that our customers have come to expect from an Elster meter: four-quadrant metering, active, reactive, and apparent energy and demand measurements. Standard event logs and time-of-use metering are also available. The 16-segment character LCD with optional backlight provides a flexible interface to the user for displaying meter data. Additionally, the A1800 ALPHA meter features optional upgradeable memory for both billed and non-billed interval data.

 

TRueQ (tamper restraint and quality) offers multiple anti-tampering and advanced security features for the A1800 ALPHA meter to ensure revenue protection for our customers. The meter’s site diagnostic capability continuously monitors the service, verifying that all phases are present and that the wiring configuration is correct. Adverse or abnormal conditions, such as phase outages and reverse energy events, are logged.

 

Different meters within the A1800 ALPHA meter family have specific capabilities, as shown for the A1810, A1830, A1860, and A1860 meter sections.
