7 A/B/C-Channels 3 Types for Every Application 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. Accuracy High-precision measurements at high bandwidth Precise measurements on 50Hz applications Cost-effective broadband measurements khz 500 khz 10 MHz Bandwidth 7

9 Channels Right Type for Every Application. Save Money Example: Electric Drive System 2-4 AC DC DC AC M C-channel A/B-channel A/B-channel 1) 2) 3) 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. 9

10 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 processing 10

11 DualPath Twice the Results, Half the Time Scope display of the voltages at the converter output. The wideband values ( ) show the PWM signal. The narrowband values ( ) are sinusoidal. 11

12 DualPath Twice the Results, Half the Time 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. 12

53 LMG600 with LMG Test Suite 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 gridvoltage 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 compatibility and eco-design of energy-using products must be observed and fulfilled as well. 53
