Model G5 -Measuring Module for Cell Voltage Monitoring (CVM)
The CVM measurement modules for precise cell voltage measurement on fuel cells, batteries and electrolyzers have proven themselves hundreds of times and deliver reliable measurement results even in harsh field conditions. Thanks to a variety of interfaces, they can be used excellently with common PC systems as well as in embedded systems. For processing the measurement signals and combining them with other modules of the MCM family, process modules are available that allow PC-independent signal processing up to free programmability via scripting.
The CVM G5 modules are intended for CVM systems used in research & development, laboratories and test vehicles. The ultra-compact design, tightness and temperature resistance not only allow the use on test benches, but also in harsh environmental conditions in mobile applications such as automotive and navy.
Areas of application in detail:
- Marine
- Vehicles
- Stationary systems
- Electrolysers
- Batteries
- Fuel cells
Our CVM systems for test applications can be positioned close to the DUT. They feature galvanic signal isolation, digital signal pre-processing, cascadability as well as CAN and TCP/IP interfaces and are easily adaptable to all typical test bench requirements.
The systems based on the CVM G5 module family are also used in test stands and HiL systems. One example is our test system for fuel cell controls.
Due to their robustness and small size, CVM systems based on the G5 monitoring modules are also ideally suited for use in prototypes. For example, they are used in passenger cars for testing fuel cell drives.
The CVM G5 measuring modules feature an ultra-compact design and a high degree of modularity. Each module has 10 channels. The measurement can take place in the range from -1 to +5 V or from -3 to +3 V.
A measuring system always consists of a communication module, a termination module and up to 59 measuring modules.
