For submetering and energy management systems

This combined energy meter and power analyser with large embedded memory is mostly suitable as a data collecting workhorse for distributed energy management systems. It is measuring and recording all relevant information about the utilisation of electrical energy in the measured point. Energy consumption (or generation) is archived separately - kWh and kvarh in import or export, separated in up to three tariffs (TOU), separately per-phase and as a total sum.

Currents are measured with a hole-through current transformers embedded right on top of the instrument. Nominal current of the actual item can be chosen between 5A and 150A. This design brings significant savings in installations as the instrument does not need external CT.

Properties

Remote Control

The instrument is equipped with remote communication port, digital or analog inputs and outputs and alarm LEDs. There is no display nor any buttons on the instrument and the whole setup is done over the communication interface. The main advantage of this feature is that in places where it is intended to be used it does not attract an unnescessary attention. As such it can serve as a full featured analyser or energy meter with unatended remote reading. The SMC instrument can be also preprogrammed to serve autonomous command and control functions in various situations as for example to control the load of some apliances towards the total energy consumption - load control (load management, ripple control).

Software for management of SMC instruments

Configuration, data acquisition, archivation and analysis can be performed in ENVIS and ENVIS.Online software version 1.1. Basic features of ENVIS software are available free of charge.
