A1800 ALPHA meter

The A1800 ALPHA® is a world-class, highly accurate, robust, system ready meter that is ideally suited for 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; 16-segment character LCD with optional backlight provides a flexible interface to the user for displaying meter data; and optional upgradeable memory for both billed and non-billed interval data

TRueQ (tamper restraint and quality) offers multiple anti-tampering and advanced security features that ensures revenue protection for our customers. The 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, see the A1805, A1810, A1830, A1860, and A1880 tabs.

The A1800 ALPHA meter supports the ANSI C12 standards for both local (optical) and remote (modem) communication.

Additionally, the A1800 ALPHA meter can also support the DLMS standards for both local and remote communication. When equipped with the optional DLMS communication support, the meter supports both ANSI C12 and DLMS communication. When establishing a communication session, the meter automatically determines the protocol being used and responds in the same protocol.
