DEWETRON’s high-precision power analyzers are a unique combination of a flexible hardware and a high-end software. Measure high-voltage and current in perfect synchronization with further analog inputs such as temperature, vibration, noise as well as other data sources such as CAN, SCPI or FlexRay.
With an extreme low measurement error of only 0.03 % yet a sample rate of 10 MS/s, raw data recording, up to 16 power phases (16x U, 16x I) and test bed integration possibilities, we offer the ultimate mixed signal power analyzer for your power measurement tasks.
Since the heart of a DEWETRON power analyzer is the TRION(3) power measurement board, it can of course be placed in any DEWETRON system – from the ultra-compact TRIONet3 to the portable DEWE3-A4 and the large DEWE3-RM systems for fixed installation in e.g. test stands. In case you have several measurement positions that are locally distributed you can connect several chassis via network and create a distributed data acquisition system to keep the sensor cables short and minimize the EMC influence.
OUR SECRET: Flexible POWER MODULES
Enjoy maximum flexibility with user-exchangeable plug & play power modules: Choose your suitable power modules, plug them into your DEWETRON DAQ system, turn the system on and start to measure. Select between different power modules of the TRION(3) series for 4-phase power analysis and up to 10 MS/s sampling rate. Because of the unique modularity, 4 slots on each power module (8 slots of the TRION3-1810-SUB-8) can be equipped with different sub-modules for direct current or voltage measurements and connect it to almost any kind of current or voltage transducer.
The power analyzer can use its full potential with our easy-to-use OXYGEN measurement software, which supports you with a huge amount of software features. OXYGEN seamlessly integrates data being transmitted through multiple, totally synchronized signals into calculations for power analysis.

Several power systems are logically summarized into power groups
Gapless cycle-by-cycle calculation, no blind spots
The power accuracy of DEWETRON’s power analyzers is stunning. Compared to other power analyzers available on the market, it offers a constant low measurement error of only 0.03 % from 0.5 Hz to 1000 Hz fundamental frequency. Moreover, it comes with a calibration certificate according to ISO 17025. High-precision measurements over a wide frequency range are an easy task with our power analyzers and central requirement for test stand applications.
RAW DATA RECORDING
Do you want to record waveform data, different signals such as noise, temperature, speed, torque and do also power analysis? Our DEWETRON power analyzer combines it all. Benefit from reliable gapless raw data recording of any analog or digital signal and from simultaneously high-performance power calculation of several power groups.
PROFIT FROM HIGH DYNAMIC RANGE
DEWETRON’s power modules provide fast acquisition rates up to 10 MS/s and 18-bit A/D conversion as well as the best linearity of signal conditioning. In addition, the power modules offer the highest dynamic performance in the whole input range: up to 1000 V (±2000 VPEAK) and 20 A (±40 APEAK) with the highest possible accuracy for all your dynamic applications.
100 % SYNC OF ADDITIONAL SIGNALS
Our power analyzers are also mixed-signal recorders, which means you only need ONE system for all inputs. Just expand your power analyzer with additional TRION(3) modules for other signals/sensors, e.g. electrical data, mechanical data, vehicle bus data, video, sound, positioning data, etc.
One power analyzer for the synchronized acquisition of different signals – even raw data – and their storage in one data file.
EASY TEST STAND INTEGRATION
Test stand manufacturers trust DEWETRON’s measurement data for reliable testing. Our interfaces ensure easy integration. Smart interface technology seamlessly integrates DEWETRON power analyzers into test stand automation systems like PAtools® from Kratzer Automation.
Instruments are equipped with the right interface for reliable data transmission, remote control, and configuration via TCP/IP-based protocols, tailored to test stand architectures.
To provide customized tools for e-motor development, DEWETRON and Müller-BBM VibroAkustik Systeme provide an integrated testing solution for e-NVH and e-power. DEWETRON’s precise power analyzers can stream their data into the PAK live.hub from Müller-BBM Vibroakustik Systeme. The data is synchronized and can be used to analyze the correlation of the electrical and acoustical domain with PAK.
