LMG641 1-4 Channel Power Meter

LMG641 Dual-Path Power Analyzer

As the LMG671’s “younger brother”, the LMG641 features all of the breakthrough innovations of the LMG671, housed in a space-saving form factor at an attractive price.
Its DualPath architectures offers simultaneous narrow- and broad band measurements through two independent measurements paths. The LMG can be configured with up to 4 measurement channels.Three different Channel Measurement Modules are available : A1 module for high precision broadband measurement, B1 module for general purpose measurements and the C1 module for precision 50/60 Hz measurements.

  • Outstanding accuracy of 0.015% of measured value + 0.01% of range
  • Full dynamic range of 500 µA to 32 A / 3 mV to 1000 V
  • Analog bandwidth DC up to 10 MHz
  • Modular configuration with 1 to 4 power measurement channels
  • Gapless sampling up to 18 bit and cycle time <30 ms
  • Delay time between V and I input < 3ns,
  • DualPath: Simultaneous independent measurement of narrow- and broadband
  • Harmonics and inter harmonics up to 2000 th order,as required by EN61000-4-7
  • With optional I/O card speed/torque inputs freely configurable for all signal types (analogue, frequency as RS422,TTL or HTL) via menu
  • Flexible scripting tool for custom applications
  • Simultaneous measurement of V, I, P values and harmonics
  • Signal filters freely configurable by frequency, type and characteristics
  • Synchronization to up to 7 different frequencies simultaneously
  • Flicker measurement, interactions between grid and appliance according to EN61000-4-15
  • Large and clearly arranged touchscreen GUI for intuitive handling
