The meters have the following basic characteristics:
■ Recording of active energy and Reactive energy in one or more
tariffs
■ Display of data with a liquid crystal display (LCD) and backlit
Standard Comments
■ Compliance with accuracy classes 1 according to IEC
■ Correct measurement even with the failure of individual phases or
when used in two- or single-phase networks
■ Wide range of measurement from starting current to maximum
current
■ Serial interface with optical for meter data readout and
configuration
■ Pulse output for transmission of constant pulses
■ Load profile, Billing and Max.Demand function available
■ Detection of strong magnetic, meter cover opening, terminal cover
opening and bypass tampering.
■ Built-in relay switching for remote load disconnect and reconnect
