Precision in Power

is the guideline of ZES ZIMMER Electronic Systems GmbH.

ZES ZIMMER is a German high-tech company specialized in developing, manufacturing and

distribution of precision instruments and systems for measuring electrical power, energy,

harmonics, flicker and power quality.

The company is based in Oberursel, Germany, and was founded in 1980 by

Dipl.-Ing. Georg Zimmer. It is one of the technical leaders in the field of power analysis

worldwide.

ZES ZIMMER offers professional service and support to help customers optimize their

A/B/C-Channels 3 Types for Every Application

7

Power analyzers are available in different accuracy classes, to allow the user to choose

the right tool for the job at hand. After all, not all applications require maximum precision;

often lower resolution and frequency range are sufficient. This is why the LMG600 series

offers three different channel types, which can be combined in the same chassis without

problems to ensure that you always have a measuring device tailored to your needs.

C-channel A/B-channel A/B-channel

1) Input of the converter: C1-channels are usually sufficient for this.

2) DC intermediate circuit: depending on the required level of precision, A1 or B1-channels

are required, as the DC intermediate circuit exhibits significant residual ripple under

certain circumstances.

3) Converter output: depending on the required level of precision, A1 or B1-channels only

are to be used.

Filters. Accuracy without compromise

In this menu the

filters and wirings

can be set.

For several signals, it is

necessary to fit filters

or change the signal

coupling/wiring to get

the right values. You

can adjust this settings

separately for each

group.

You can select Single

Path or Dual Path signal

The narrowband values ( ) are

DualPath Twice the Results, Half the Time

12

Simultaneous measurement in two bandwidths

DualPath - No compromises, No doubt

The LMG670 was the first power analyzer to have two A/D converters in two independent signal paths for each current and voltage channel. One for the filterless measurement of the wideband

signal, and a second for the narrowband signal at the output of the anti-aliasing filter. The

parallel processing of the digitized sample values gives the user access to both measurements

of the same signal, without risking aliasing effects.

This unique procedure has established itself for the complete LMG600 series.

It avoids all of the downsides of previous approaches and guarantees the most precise result in

the shortest time possible. The LMG600 series power analyzers get all necessary values in one shot.

Fast. Reliable. No hassle. No compromises. No redundant work.

CE-Compliance

The use of power electronics devices causes power or rather current depending noise on the grid or your network, which reduces the quality of your grid voltage or interferes other

connected devices.

Therefore, electrical installations, systems and

equipment must comply with the EU directives and

regulations, when they are placed on the market

within the EU.

Other guidelines for electromagnetic compatibilityand eco-design of energy-using products must be

observed and fulfilled as well.
