High-voltage and current inputs
The LITE[PA] features 4 or 8 fixed high-voltage inputs and 4 or 8 selectable sub-modules to connect all state-of-the-art current sensors. The fixed inputs for high-voltages offer a range of ±2000 VPEAK, a 5 MHz bandwidth, a 2 MS/s sampling rate and a CAT III 1000 V safety class.
The current inputs have 1 ARMS (±2 APEAK) measurement range and are the ideal solution for current measurements with zero flux transducers. Other submodules for current measurements with current clamps or direct current measurements are available as well

Motor inputs
The LITE[PA] is equipped with 2 advanced counter inputs to support speed measurement with encoders and 2 basic counter inputs for torquemeters providing a frequency output signal. This allows mechanical power measurements, efficiency analyses and online efficiency mapping when working with the LITE[PA].
OXYGEN measurement software
The LITE[PA] comes with our easy-to-use OXYGEN software. Within a minute, the basic measurement setup is ready, e.g. a 6-phase system with 1000 A current transformers, and all typical power parameters can be displayed and saved. Design your own views by choosing from a variety of displays and assigning signals using drag and drop. Additional online data processing such as mathematics, special statistics, filtering, etc. is easily possible at any time. Also, the efficiency map of a drive train can be calculated and displayed directly during the measurement. For offline analysis and reporting tasks, the software can be installed license-free on any number of analysis PCs.

High wideband accuracy
The power accuracy of DEWETRON’s LITE[PA] is stunning. Compared to other Power Analyzers available on the market, it offers a constant power accuracy of 0.04 % from 0.5 Hz to 1000 Hz fundamental frequency. High-precision measurements over a wide frequency range are an easy task with the LITE[PA] and central requirement for test stand applications.
The system is delivered with a factory calibration certificate. An accredited calibration, traceable according to ISO 17025, can be done on request.
Data connection to host system
The LITE[PA] is ready to be easily integrated into a wide variety of host systems. Data transfer to the testbed control can be easily realized by using the protocols SCPI, Ethernet UDP or CAN. XCP is available on request. The remote configuration and control of the LITE[PA] is ensured by a power SCPI command library to, e.g. load predefined setups, edit the channel configuration or make trigger settings.
Intuitive user interface
The LITE[PA] power analyzer impresses with a very intuitive user interface for direct device operation, e.g. in laboratory use. It has a bright 11.6” multi-touch Full HD display for quick and easy operation. You can operate our intuitive OXYGEN measurement software via simple multi-touch gestures and smart visuals, just like on a smartphone. Alternatively, you can connect a keyboard and a mouse too.
Temperature measurement with XR expansions
Expand your LITE[PA] power analyzer with our low-speed XR modules for the acquisition of temperature, current, voltage or RTD. All different types support either RS-485 or CAN data output. The output type can be programmed by the user. Each of the 8 measurement channels has its own A/D converter with a sampling rate of up to 200 Hz.
