The LMG671 One- to Seven-Channel Power Analyzer from ZES ZIMMER Electronic Systems provides one-shot results for narrowband, full spectrum, and harmonics, with an accuracy of 0.015% of the measured value at +0.01% of the dynamic range from 500 µA to 32 A / 3 mV to 1000 V per channel. It can deliver power measurements from standby to full load (max. 32 A) without mechanical changes, and has an analog bandwidth from DC up to 10 MHz.
The analyzer offers a modular configuration with 1 to 7 power measurement channels (alternatively 6 channels + 1 I/O card), with gapless sampling up to 18 bits and a minimal cycle time of 10 ms. It provides simultaneous measurement of narrow- and broadband values through the company’s DualPath architecture, along with simultaneous capturing of fundamental frequency and broadband RMS values for instantaneous detection of losses, especially for high-frequency components.
Features include harmonics and interharmonics up to 2000. order, as required by EN61000-4-7, with optional I/O card speed/torque inputs configurable for all signal types (analog, frequency as RS422, TTL or HTL) via menu, along with a flexible scripting tool for custom applications. The analyzer can provide simultaneous measurement of V, I, and P values, as well as harmonics, presented in tabular or graphical form, with signal filters configurable by frequency, type, and characteristic, with synchronization of up to 7 different frequencies simultaneously.
