DMG 900...
expandable digital analyzers are available with a flush-mount
housing, 96x96mm size. The wide graphic touch screen display
provides extremely simple interacting between the instrument and the
user.
The high performance of the analyzers gives very accurate
measurements and can control energy distribution systems, to detect
and prevent energy problems which could compromise quality and
supply. The main features of these analyzers include an extensive
power supply voltage range, high measurement accuracy, expandability
up to 4 plug in expansion modules.
The
main electric parameters are:
Voltage: phase, line and system
values
Supply voltage value for the DC
supply type only
Current: phase values
Neutral current calculated and
true values
Power: apparent, active and
reactive phase and total values
P.F.: Power Factor per phase and
total
Cosphi per phase and total
Frequency of measured voltage
value
Voltage and current
asymmetry
Total harmonic distortion (THD) of
voltage and current values
Harmonic analysis of voltage and
current up to the 63° order
HIGH/LOW function: instantaneous
measurement and storing of minimum and maximum values of
voltage, current, power P.F.,
cosphi and frequency
Averaging function
Maximum demand of power and
current values
Flow direction of harmonic power
values
Energy meters for active,
reactive, apparent partial and total values with programmable
tariff functions
Hour counter for programmable
total and partial hours
Pulse hour counter for general
use: pulse counting for water, gas, etc. consumption with
expansion module only
Analysis of power quality to EN
50160 with expansion modules.
