Flush-mount LCD touchscreen power analyzers, expandable

DMG 900... expandable digital power analyzers are available with a flush-mount housing, 96x96mm/3.78”x3.78”. The wide graphic touch-screen display provides extremely simple interacting between the device and the user. The high performance of the power analyzers gives very accurate measurements and can control energy distribution networks, to detect and prevent energy problems which could compromise quality and supply. The main features include an extensive power supply voltage range, high measurement accuracy, expandability up to 4 plug-in expansion modules. There also is available the DMG 900T measurement transducer which can be used with the DMG 900RD remote display. The DMG 900T, without display, is arranged for mounting inside the panel board, on 35mm DIN rail, and is an ideal solution for installations where the measurements of various multimeters must be remotely viewed. The DMG 900RD remote display connected to the DMG 900T transducer can display the measurements on the panel front.

Main measurements and functions include:

• Voltage: phase, phase-neutral and ground neutral-earth
• Supply voltage value (only DMG... D048)
• 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
• Cos ϕ per phase
• Frequency of measured voltage value
• Voltage and current asymmetry
• Total harmonic distortion (THD) of voltage and current
• Harmonic analysis of voltage and current up to the 63° order
• HIGH-LOW-AVERAGE value functions for all measurements
• Maximum demand of power and current values
• Energy meters for active, reactive, apparent partial and total values with programmable tariff functions
• Hour counter for programmable total and partial hours
• Pulse counter for general use: consumption pulse counting for water, gas, etc., with expansion module only
• Energy quality analysis to EN 50160 Class B (with expansion module).
