  • Description

    Elster A1140 Single/Three Phase Smart Meter

    The Elster A1140 Single/Three Phase Smart Meter is a secure, adaptable smart meter which can be used in commercial or light industrial contexts. It measures both kWh and kvarh electricity and can monitor single-phase and three-phase networks whilst load profiling helps data collection and analysis. 90 days’ worth of data profiling can be collected in fewer than 30 seconds and the device boasts a range of communications technology - including an RJ11 socket - to aid remote access and management.

    The Elster A1140 is also MID-approved and highly accurate so the user can have complete confidence in all the readings whilst benefitting from the clear, 8-digit, LCD display for local access and data recording. The unit comes with Power Master Unit software for Windows which allows the user to efficiently analyse data both on and off site. The internal clock with battery back-up ensures that recordings are accurately timed and the comprehensive security measures make sure that information is correct.

    With a 10-year product life, the A1140 provides excellent, reliable electricity usage monitoring for a wide range of environments, and has several different features to allow for power cuts, tampering, and electricity pulses.
