DEWETRON’s Mixed Signal Power Analyzers are the best solution
for high-performance power analysis.
Thanks to the low measurement error of 0.03 %, the Power Analyzer achieves very high accuracy, even with low range utilization. Precision accuracy is guaranteed through the whole analysis.
Fast acquisition rates of up to 10 MS/s and 18-bit A/D conversion, as well as the best linearity of the signal conditioning, offers the highest dynamic performance in the whole input range – up to 1000 V and 20 A with the highest possible accuracy for all your dynamic applications.
Up to 10 MS/s/ch and high dynamic range guarantee data integrity.
A DEWETRON Power Analyzer is the solution for the analysis of several motors, converters or complete drive trains simultaneously. Up to 16 different power phases and the capability for calculation of power parameters even for polyphase motors (up to 9 phases) turns the Power Analyzer into a multi-power analyzer.
Waveform data, mixed signals and power analysis? A DEWETRON Power Analyzer combines all. Reliable gapless raw data recording of any analog or digital signal and high performance power calculation of several power groups simultaneously.
Our Power Analyzers are also mixed-signal recorders, that means you only need ONE system for all inputs:
Do you need more input channels? No problem, the Power Analyzers can be extended in many ways. Just add another TRION module, if there is a free slot. Data is automatically synchronized across all channels.
The Power Analyzers provide integrated (redundant) power supply for 8 current transducers. The integrated transducer power supply enables the engineer to relinquish an additional supply box and connect the transducers directly to the Power Analyzer.
Most of the common sensors with ±15 V or +9 V are compatible, also demanding ones (like zero-flux transducers) can be powered thanks to the superior power supply.
Smart interface technology makes it easy to integrate a Power Analyzer into automation systems and testbed environments while it is guaranteeing reliable data transmission, easy to use remote control and remote configuration through TCP/IP based protocols in compliance with standardized protocols (e.g. ASAM) and file formats.
OXYGEN Measurement Software seamlessly integrates data being transmitted through multiple, totally synchronized signals into calculations for power analysis.
Our Power Analyzers are optionally supplied with an EN ISO/IEC17025 certification. Calibration and adjustment are done in the accredited calibration laboratory at the DEWETRON headquarters in Graz/Austria.

Analysis of harmonics, interharmonics, and higher frequencies as well as voltage fluctuations and flicker emissions are done according to industry standard.
DEWETRON provides with CAT IV the highest safety class for Power Analyzers on the market.
To provide customized tools for e-motor development, DEWETRON and Müller-BBM VibroAkustik Systeme now enable an integrated testing solution for e-NVH and e-power.
Our power analyzers precisely acquire currents and voltages with 10 MS/s sampling rate and can now be connected to the data stream of NVH systems via the PAK device cloud, the live IO hub of Müller-BBM VibroAkustik Systeme. The measurement data is time-synchronous. In this way, electrical quantities, such as power and efficiency values, of electric motors can be directly correlated with NVH data, such as housing vibrations and emitted sound. This allows to view these correlated phenomena in an extended context and to tune the control of the e-motor on the test bench directly.

Thanks to DEWETRON’s modular approach, any TRION3/TRION-based DAQ system can become a power analyzer. You can choose between several types of power modules with 8 input channels. Because of the unique modularity, at least 4 channels can be equipped with different user-exchangeable sub-modules for direct current or voltage measurement. So almost any kind of voltage or current sensor can be connected to a DEWETRON power analyzer. In the following comparison, you see DEWETRON’s dedicated power analyzer chassis.
