A DEWETRON DEWE3-PA8 Power Analyzer is the solution for the simultaneous analysis of several motors, converters or complete drive trains. What’s more, up to 16 power channels and the capability to calculate power parameters. For example,聽 polyphase motors (from 1 to 9 phases), turn the DEWE3-PA8, with PXI Express technology, into a multi power analyzer.

Mixed Signal Recorder

Waveform data, mixed signal and power analysis?DEWETRONs new Power Analyzer does it all. Reliable, gapless recording of any analog or digital signal. At the same time,聽high performance power calculation of several power groups simultaneously. And significantly, up to 10 MS/s/ch and high dynamic range guarantees data integrity.

Test Bed integration

Smart interface technology makes it easy to integrate a DEWE3-PA8 Power Analyzer into automation systems and test bed environments. While also guaranteeing reliable data transmission, easy to use remote control and remote configuration through TCP/IP based protocols. These protocols are in compliance with standardized protocols (e.g. ASAM) and file formats.

Predefined Measurement Displays

Predefined measurement displays like vector scope

Dedicated measurement displays with classic design provide critical data values at a glance. In addition, predefined measurement displays for each user defined group of power channels present an overview table, vector scope and harmonic chart. Different styling presets and data presentation tools are available to tailor the display to your exclusive needs.

Compliance to Industry Standards

Compliance to industry standards like IEC 61000-4-7

Analysis of harmonics, interharmonics and higher frequencies as well as voltage fluctuations and flicker emissions are done according to industry standard.

  • Firstly, IEC 61000-4-7
  • Secondly, IEC 61000-4-15
  • Finally, IEC 61400-21

High Resolution & Multi-touch Display

Accessible and orderly arrangement of signal inputs and power parameters directly on the front. In other words, everything at a glance!

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 synchronisation
  • Counter and analog output

High dynamic range

Fast acquisition rates and 18-bit A/D conversion.聽 As well as the best linearity of the signal conditioning offers the highest dynamic performance in the whole input range. Thanks to the low range error of 0.01 %, the DEWE3-PA8 Power Analyzer achieves a very high accuracy, even with low range utilization. Of course, precision accuracy is guaranteed throughout the whole analysis.

Active transducer supply

The integrated transducer power supply enables the engineer to relinquish an additional supply box and connect the transducers directly to the DEWE2-PA8. Most of the common sensors with 卤15 V or +9 V are compatible, also demanding ones (like zero-flux transducers) can be powered thanks to the superior power supply.

ISO17025 Certified

What is a High Speed Power Analyzer?

A high speed power analyzer is a power analyzer that offers high speed data acquisition and precision power analysis. Record every single sample into your data file, not just a few seconds. 聽

High Speed Power Analysis Applications

DEWETRON鈥檚 Multi Power, High Speed Power Analysis Hardware (DEWE3-PA8) is seamlessly integrated into Automation Systems and Test Benches with smart interface technology. For example, Gbit Ethernet, USB3.0, Ether CAT, SCPI, and XCP. 聽Also standard are gapless data recording, effortless remote control for hazardous or hard to reach environments and remote configuration of the power analyzer through TCP/IP based protocols. Our TCP/IP complies with standardized protocols such as ASAM and file formats.

Analyze multiple motors (even polyphase motors up to 9 phases), converters or complete drive trains simultaneously with guaranteed reliable data transmission. ANother key point; up to 16 power channels are available for any DEWETRON signal conditioning card. What鈥檚 more, all DEWETRON signal conditioning cards have an integrated A/D converter, standard.

In addition, our TRION鈩 signal conditioning card offers 18 bit A/D conversion and the industry鈥檚 best linearity of the signal conditioning. This linearity sets the stage for a continuously high dynamic performance along the complete input range. Even with low range utilization, the DEWE3-PA8 High Speed Power Analyzer鈥檚 lower power error of 0.04% delivers high accuracy throughout the entire analysis.
