THE ADVANCED POWER ANALYZER: DEWE3-PA8
Description
A DEWETRON DEWE3-PA8 is the solution for analysis of several motors, converters or complete drive trains simultaneously. Up to 16 power channels and the capability for calculation of power parameters even for polyphase motors (up to 9 phases) turns the DEWE3-PA8 into a multi power analyzer.
The new 8-slot PXIe backplane, which supports the brand-new TRION3-series, allows sampling rates up to 10MS/s. Combined with high speed SSD technology a data throughput of up to 1GB/s is possible. With this feature, you get every single sample into your data file, not just a few seconds.
Smart interface technology makes it easy to integrate a DEWE3-PA8 into automation systems and test bed 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.
Dedicated measurement displays with classic design provide critical data values at a glance. A predefined measurement display for each user defined group of power channels presents 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.
The 11.6” high resolution display is very bright for maximum readability and ample space for user defined screens.
Analysis of harmonics, interharmonics and higher frequencies as well as voltage fluctuations and flicker emissions are done according to industry standard.
IEC 61000-4-7
IEC 61000-4-15
IEC 61400-21
You need more input channels? No problem, the PA8-series can be extended in many ways. Just add another TRION™/ TRION3 module, if there is a free slot or use a TRIONet or another Front-end system for a higher channel count. Data is automatically synchronized across all channels.
The integrated transducer power supply enables the engineer to relinquish an additional supply box and connect the transducers directly to the DEWE3-PA8.
Fast acquisition rates 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. Thanks to the low power error of 0.03 %, the DEWE3-PA8 archives a very high accuracy, even with low range utilization. Precision accuracy is guaranteed through the whole analysis.
