DIGITAL ENERGY METERS

Energy saving is now a key issue of management strategies at all levels, from families to large companies. The common goal is to reduce energy requirements in order to reduce costs, both in monetary terms and environmental terms. To achieve success in this relation, it is important to constantly measure and analyse energy flow using instrumentation that provides a high level of accuracy and that is applicable to various supply points to obtain precise data properly.

Lovato Electric counts on satisfying all the requirements mentioned with the new DME series of modular power meters, with mechanical display or LCD, which ranges from a single-phase version of only one module (18mm), with direct connection to systems up to 40A, two three-phase versions, with a maximum current of 63A for direct use or through current transformers, both in a 4 module size. The series is completed with an additional two-phase module with a maximum current of 63A.The energy meters are designed and made to be evidently electrically safe and accurate according to Class B requirements of the European Directive 2004/22/EC for measuring instruments (MID).
 

Consumption can be perceived by the user by the metrological LED on front or by a programmable pulse output that can be used as an alarm when a programmed threshold is exceeded.The user can also consult values for voltage, current, frequency, power, power factor and maximum demand. In addition, there is a counter useful to monitor the operating time of a load or how long an alarm condition lasted. Three-phase versions can also operate two tariffs, configured by an AC input.

EXPANDABLE MODEL TYPE DME D310 T2

The three-phase DMED310T2 version for connection through current transformers is equipped with integrated optics port on the housing side to permit expansion of the base unit with EXM series modules.
Therefore, the energy meter can be equipped with inputs and outputs to collect signals from the field and operate on other devices. It can integrate several communications interface such as USB, RS232, RS485 and Ethernet and use a memory module for data acquisition with time stamp.
