Test Bench
DEWETRON’s modular measurement solutions are the right tools for developing and testing drive trains, electrical engines, motors and inverters as well as electric & hybrid vehicles on a test bench.
Because of the flexible and modular product concept, it is possible to analyze efficiency, electrical and mechanical power, temperature, torque rotation speed and much more with a single DEWETRON Power Analyzer.
POWER ANALYZER
DEWETRON’s measurement solutions effortlessly analyze efficiency and losses during different drive cycles, calculate the power factor of the electrical engine during acceleration or analyze the battery behaviour at different temperatures. Different interfaces and inputs provide for the capture of CAN-data, video, vibration, rotation speed, and torque simultaneously and synchronously. Sampling rate up to 10 MS/s/ch and bandwidth up to 5 MHz in combination with broadband and high accuracy transducers guarantee accurate and precise data. Plugins such as Combustion Analyzer or Power allow our customers to analyze and test hybrid cars with one DEWETRON Power Analyzer. The modular product concept allows configuring systems with up to 16 power faces in one system. With optional racks and expansions, it is possible to configure the perfect measurement solution for your test bench application. The software OXYGEN with Power option guarantees highly accurate data on a stable, modern and expandable platform. The easy to use software with auto-configuration helps you to save time and get your work done. DEWETRON’s solutions are professional tools for professionals in R&D, certification and test.
