FIXED HIGH-VOLTAGE & CURRENT INPUTS
The LITE[PA] features 4 or 8 fixed high-voltage inputs and up to 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 selectable sub-Modules are compatible with all current sensors and direct current measurement.

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 the typical power parameters are available to be displayed and stored. Freely design your own views by selecting 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.

ABSOLUTE HIGH 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.

DATA CONNECTION TO HOST SYSTEM
The LITE[PA] is ready to be easily integrated into a wide variety of host systems. In addition to the CAN-bus, the data can also be transmitted via Ethernet, with various protocols such as SCPI or XCP. The remote control is usually done via SCPI; extensive commands are available to e.g. load predefined setups, make trigger settings etc.

USER-FRIENDLY MULTI-TOUCH DISPLAY
The LITE[PA] power analyzer has a bright 11.6” multi-touch Full-HD display for quick and easy operation. You can use our intuitive measurement software OXYGEN via simple multitouch gestures and smart visuals like you would on a smartphone. Alternatively, you can connect a keyboard and a mouse too.
