LTTsmart - Precision Power Analyser

The LTTsmart power analyser is a consistent further development of our precision measuring devices. In DIN rail housing ideal for use in industry.

The Power Analyser

With its high measurement accuracy and high prezision power anlyse, the power analyser is optimally suited for the development of electromobility.

The power analyser in the aluminum housing consists of one module with two channels each and can be flexibly extended by several modules. The two channels of a module can be optionally equipped with 1000 Vrms and 10 Volt (power analyser light) or 1000Vrms and 1000Vrms (power analyser) high voltage input option with banana plug.

The connection to the PC is located in a separate base module. (picture: module left side)

The power analyser is also available as a portable version with handles and in a 19" housing up to 32 channels.


Important facts:

  • up to 4 MHz sampling rate per channel
  • 1.7 MHz bandwidth
  • extremely high precision: 0.015%*signal + 0.015%*range
  • 24 bit A/D converter - extremely low noise and distortion free
  •  highly synchronous up to 16 channels per device as well as multiple devices
  • 2500 VDC galvanic isolation of all channels
  • perfectly fulfills the requirements of DIN IEC 60034-2-3-3
  • voltage and current inputs: up to ±1000 Vrms
  • optionally ICP®, charge, strain gauge and/or pulse
  • compact and robust for operation near inverters

The LTTsmart as a power analyser is perfectly suited for use in power analysis of batteries, inverter signals on battery-powered electric motors  or photovoltaic, in the field of OEM test bench construction, aircraft power systems or for power quality measurement.

How the power analyzer works

The advantage of the Power Analyzer is the perfect measurement chain from the precise preamplifier, the real-time data transmission to the PC, up to the real-time analysis of the data.
