A DEWETRON DEWE2-PA7 is the solution for the simultaneous analysis of several motors, converters or complete drive trains. Up to 12 power channels and calculation of power parameters even for polyphase motors (from 1 to 9 phases) turn the DEWE2-PA7 into a multi power analyzer.

Mixed Signal Power Analyzer and Recorder

Icon gapless recordingIcon for 1 TB Storage Capacity

Waveform data, mixed signal and power analysis? Reliable gapless recording of any analog or digital signal. High performance power calculation of several power groups simultaneously. Up to 2 MS/s/ch and high dynamic range guarantee data integrity.

Simple Integration into Testbeds

Icon for Gigabit EthernetIcon for USB 3.0icon for ASAM and MDF4 protocol

Smart interface technology makes it easy to integrate a DEWE2-PA7 into automation systems and test bed environments. Further, it聽 guarantees reliable data transmission, easy to use remote control and remote configuration through TCP/IP based protocols and file formats. Protocols are in compliance with standardized protocols such as ASAM.

Predefined Measurement Displays

Predefined measurement displays like vector scope

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.聽 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.

  • IEC 61000-4-7
  • IEC 61000-4-15
  • IEC 61400-21

High Resolution & Multi-touch Display

high resolution screen of power group with multi-touch operation

The 9鈥 high resolution display is very bright for maximum readability and ample space for user defined screens. Also the few necessary settings are easily accessed with just a few swipes on the multi-touch display.
Accessible and orderly arrangement of signal inputs and power parameters directly on the front. 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
  • XCP via LAN
  • High number of mid speed inputs for low dynamic signals (e.g. temperature)
  • GPS synchronisation and positioning
  • Counter and analog output

Integrated transducer supply

The integrated transducer power supply enables the engineer to relinquish an additional supply box and connect the transducers directly to the DEWE2-PA7. 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

Application: DataCenters 聽and the Precision Power Analyzer

Precision Power Analyzers are used to ensure and prove the reliability, failure safety and efficiency of the energy supply/distribution and backup solutions in a data center. With this purpose in mind, the ultimate objective is to keep or raise the failsafe performance and to reduce the PUE! Why is this important?

Generally, an increase of the fail safe performance is an extremely good selling point! On the other hand, a lower PUE is a guarantee for highly efficient SUB-Systems.

Energy Consumption

The energy consumption of SUB-Systems, like power distribution, lightening, cooling and power backup is approximately 50% of the total energy consumption. For example, approximately 33% of the total energy consumption is used for cooling. Up to 65% of 鈥渃ooling energy鈥 is wasted and can be not used for cooling servers. 聽A small optimization of the grey space (2.5%) leads to an additional turnover/profit of up to 0.83 Mio. EURO (or 6.8 Million kWh) for the Data Center[1] per year! Additionally, a DEWETRON Power Analyzer helps to locate energy wastes and reduces energy consumption, therefore increasing of the efficiency of the entire Data Center.


With a precision power analyzer聽it鈥檚 possible to replace or combine at least 3 legacy measurement instruments (Power Quality Analyzer, Power Meter, Recorder, Power Scope, 鈥) with a single device. This creates a common database (鈥渟ingle point of truth鈥), uses a single powerful Software Solution for Measurement and Analysis (the use of additional analysis tools is no longer necessary, reducing the cost of licenses by approx. 8000 EUR per year). The resulting reduction in required resources allows these resources to be re-applied elsewhere (reducing the number of Power Analyzer/DAQ Systems, reducing training effort/expenses, and reducing the cost of calibration and maintenance). Overall a DEWETRON Power Analyzer聽leads to saving of approx. 0.9 Mio. EUR per year!
