High-Voltage Safe Measurement Systems High-Voltage Safe Measurement Systems

HV AD ECAT Measurement Modules

Measurement Ranges up to ±90 V and up to 1 MHz data rate

Specifically designed to be operated in high-voltage environments, these measurement modules, equipped with 4 analog inputs, provide safety for analog voltage measurements, optional with galvanically isolated sensor excitation.

HV AD4 ECAT Modules convince with their compact design and are ideally suited for use in the field of e-mobility, e. g. in engine compartments. In the test bench version, the modules can be easily embedded in existing configurations thanks to the 19-inch plug-in module. With a measurement data rate of 1 MHz per channel, even very fast analog signals can be recorded very precisely.

Quick and easy module configuration is done via CSM’s free configuration tool CSMconfig. The modules are either operated at a CSM XCP-Gateway (measurement data acquisition via XCP-on-Ethernet) or can be connected directly to a standard EtherCAT® master (max. 10 kHz/channel).

High-Voltage Measurements - Safe, fast and precise measurements with CSM

E-Mobility: Sicher messen an Hochvolt-Komponenten von Elektro- und Hybrid-Fahrzeugen Electric mobility is the future of transportation. The development of modern electric and hybrid vehicles poses new challenges for measurement technology. Not only must the measurement technology for eMobility match the traditional attributes of being accurate, mobile, and easy to use, it must also be safe for the users and the system. CSM high-voltage measurement technology ensures the safety of all measurement applications by means of a HV safe measurement chain from the sensor to the data acquisition.
