The LTTsmart power analyzer is a development of our precise measurement devices for rapid three-phase current / voltage measurement. In a top-hat rail housing, it is ideal for the use in industrial environments.
Thanks to its combination of high measuring accuracy and high precision in power measurements, the power analyzer is ideal for development and measurement data acquisition in the field of electromobility, aviation and for use in test benches.
The LTTsmart consists of a module with two separate and galvanically isolated input channels in an aluminum pull-out profile housing. It can also be flexibly configured in terms of number, sequence and scope of performance.
The two channels of a module can be optionally equipped with 1000 Vrms and 10 Volt (power analyzer light) or 1000Vrms and 1000Vrms (power analyzer) high voltage input option with banana plug. The collected data can then be processed on the PC. The connection to the PC is located in a separate base module.
The power analyzer is also available as a portable version with handles and in a 19" housing up to 32 channels.
The LTTsmart as a power analyzer 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.
Module version | Channel description |
Power Analyzer LTTsmart HH | Ch1: Volt: ±500 mV and ±10 V, High Volt: ±1000 Vrms Ch2: Volt: ±500 mV and ±10 V, High Volt: ±1000 Vrms |
Power Analyzer light LTTsmart LH | Ch1: Volt: ±500 mV and ±10 V Ch2: Volt: ±500 mV and ±10 V, High Volt: ±1000 Vrms |
Practical advantage: The modules of the Power Analyzer can be combined with modules of the LTTsmart and the input options DMS or ICP at any time.
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.

DAQ basics part 2The software option "LTTpro Power Analyzer", specially developed for the LTTsmart, offers in interaction a high-performance electrical power measurement perfectly designed for modern electric drives at changing speeds. The LTTsmart uses highly optimised algorithms to determine and display the exact revolution cycles even from highly noisy phase current sinusoidal curves. In addition to all the usual performance data (rms values, reactive/apparent/active powers, power factors, speed, efficiency, ...), the distortions (THD = Total Harmonic Distortion) of all phase currents and voltages are also continuously determined and displayed. Calculations on a half-cycle basis and averaging over several cycles are also possible.
The parallel view of raw data and calculated Power Analyzer data immediately reveals the causes behind any abnormalities in the key performance indicators.
At the push of a button or via configurable trigger events, entire raw data time windows can be saved with the corresponding calculated Power Analyzer key figures, while the continuous power calculation simply continues.
The compact LTTsmart systems can be operated mobile not only in the test bench but also conveniently directly in the vehicle. In addition, the software can also display, analyse and forward previously recorded or emulated data, so that all requirements around driving cycles, vehicle testing, production monitoring, development and optimisation are covered.
The LTT hardware and software package thus offers an efficient solution for measuring the performance of an e-motor in the test field and in real-world use.
