Accuracy

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.

Diagram of Power Accuracy versus Frequency shows extremly little Measurement Error

High Dynamic Range

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.

Multi-Power Analyzer

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.

Raw Data Recording /
Waveform Recording

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.

Mixed-signals

Our Power Analyzers are also mixed-signal recorders, that means you only need ONE system for all inputs:

  • Modular and Mixed Signal inputs
  • Isolated high voltage & current inputs
  • High-performance auxiliary inputs (e.g. torque, speed, vibration)
  • CAN interface with input and output function
  • EtherCAT and XCP, SCPI over Ethernet
  • High number of mid-speed inputs for low dynamic signals (e.g. temperature)
  • PTP, GPS, IRIG synchronization
  • Counter

Modularity and Expandability

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 or use a TRIONet for a higher channel count. Data is automatically synchronized across all channels.

 

If you need more input channels, you can easily expand the Power Analyzer with a DEWE2 Front-end chassis for a higher channel count or add static inputs by using CPAD or EPAD modules.

Integrated Transducer Supply

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.

Testbed interfaces

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

OXYGEN Measurement Software seamlessly integrates data being transmitted through multiple, totally synchronized signals into calculations for power analysis.

 

  • Analysis of 1-9 phase power systems (1P2W, 2V2A, 3P3W, 3P4W, 6P6W, …)
  • Several power systems are logically summarized into power groups
  • Gapless cycle-by-cycle calculation, no blind spots

ISO 17025 Calibration

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.
