The range of LOVATO Electric metering instruments is continuously being extended with the release of the new graphic LCD models, DMG 200, DMG 210 and DMG 300.
The backlit graphic LCD is capable of providing these modular instruments with extremely clear, intuitive and flexible viewing of all electrical parameters of a system.
The very accurate measurements combined with their extreme compactness provide an ideal solution for every type of application.
The models are differentiated as follows:
- DMG 200 Basic version with 128x80 pixel LCD
- DMG 210 Version with built-in RS485 opto-isolated port
- DMG 300 Version expandable with up to 3 modules of the EXM series by optic
interface.
The main measurements are:
Voltage: phase, line and system values
Current: phase values (neutral current calculated)
Power: apparent, active and reactive phase and total values
P.F.: Power Factor per phase and total
Frequency of measured voltage value
HIGH/LOW function: instantaneous measurement and storing of minimum and maximum values of voltage, current, power P.F. and frequency
Averaging function
Maximum demand of power and current values
Voltage and current asymmetry
Total harmonic distortion (THD) of voltage and current values
Harmonic analysis of voltage and current up to the 31° order for DMG 300 only
Energy meters for active, reactive, apparent partial and total values with programmable tariff functions for DMG 300 only
Hour counter for programmable total and partial hours
Pulse hour counter for general use: pulse counting for water, gas, etc. consumption for DMG 300 with expansion module only.
