CVMpro60-R3 / CVMpro90-R3
Cell Voltage Monitoring System
Fuel Cell Voltage Measurement Module
Measurement Module
Features
CVMpro family modules sequentially read the values
from 60 or 90 measurement channels (CVMpro60R3 and CVMpro90-R3, respectively). The measured
values are transferred to a host computer via CAN
bus. An additional CAN bus is used to cascade several CVMpro devices.
■ Measurement module for multiple-cell voltage
measurement
■
■
■
The measurement channels are electrically isolated.
The modules are capable of measuring single or dual ■
cells.
■
■
Applications
■
CVMpro devices are used to measure voltages in
fuel cell stacks, electrolyzers, and high-performance ■
capacitors. They are deployed in mobile systems
(vehicles, submarines) and in test bench instrumentation.
Modules are cascadable
Single cell measurements in the ±1.2 V range
Double cell measurements in the ±2,4 V range
Easily integrated in existing measurement instrumentation
Capable of PC-less, i.e., standalone operation
Open-circuit detection
Wide range of module operating power
Compact aluminum housing w/ IP54 / NEMA 3
enclosure rating
■ Simultaneous availability of both condensed and
individual measurement values for monitoring
and analysis
■ Windows compatible GUI, software drivers, and
programming interfaces
► Simply. SMART.
The CVMpro device family provides a large complement of electrically isolated voltage measurement channels. A CAN bus handles the device configuration as well as the transfer of measurement data to a host
computer. Higher channel counts can be configured by cascading several devices of the same series.
CVMpro devices are ideally suited for monitoring fuel cell stacks.
