Product Details

Elster A1700 Three Phase Smart Meter (100A Direct Connected)

The Elster A1700 Three Phase Smart Meter (100A Direct Connected) is a sophisticated, versatile electricity meter which is suitable for commercial and industrial applications. It boasts all the features necessary to work well in such environments. Most importantly, it can monitor three-phase, four-wire systems as well as three-phase, three-wire systems.

The ability to facilitate complex tariffs is essential to the Elster A1700’s usability in both industrial and commercial environments. It can perform both direct connected monitoring as well as CT and CT/VT metering as a single instrument or as part of a wider monitoring system.

The clear, digital screen features a fully customisable display and optical interface for communication on site whilst the Elster A1700’s two slots allow the user to fit an input/output and an RS232 or RS485 communications module for block installation so the device is very adaptable.

Load profile data can be saved for up to 900 days whilst the user also has the option of 450 days’ load storage in addition to 370 days of instrumentation profile data. The Elster A1700’s data stream mode allows for 90 days’ worth of half-an-hour profile data to be collected in under 30 seconds.

An impressive array of communications technology can be attached to the Elster A1700, thereby catering for a wide range of functions. Possible connectivity types include PSTN, GSM, Ethernet and PAKNET so the Elster A1700 is very versatile.

Businesses, tenants, landlords, providers and consumers can have confidence in the Elster A1700 as it meets Class A, B or C for EC Directive 2004/22/EC and is therefore MID-approved. Overall, the device provides a versatile, trustworthy method of monitoring energy use within industrial and commercial settings.
