Ipetronik has introduced an innovative new dummy head for climatic/acoustic engineering and a specially developed measuring system for safe HV measurement in electric and hybrid vehicles.
The IPEacoustic head, which has a wedge-shaped design, features a binaural microphone arrangement for aurally compensated noise recording as well as a third microphone in an acoustically neutral measuring position. It is equipped with 0.5in microphones with IEPE or 200V power supply.
The IPEacoustic head enables climatic/acoustic tests to be conducted in a reproducible manner in the vehicle – with an identical installation position. The head provides space inside its torso for a noiseless high-performance PC for online measurement data processing with IPEmotion. The dummy head is compatible with standard acoustic measuring systems.
Ipetronik’s HVshunt2 features an expanded measuring range for current measurement up to +/-900A, which has been extended via a current transformer with an accuracy of +/-0.2%. Thanks to the pre-assembled customer-specific cables with HV connectors, the module facilitates tool-less and safe integration into the HV onboard power supply, which reduces instrumentation and disassembling time of the test vehicle.
