Product Description
£462.00
Dynamic measurement of DC signals with 1000 mops (measuring operation per second).
Overvoltage proof measuring input. Galvanically isolated up to 6 kV.
For connecting current ALMEMO® V7 measuring instruments: ALMEMO® 500, 710, 809, 202, 204
Applications
- Monitoring the charge and discharge processes during the development of rechargeable batteries/batteries for electromobility and for other battery-operated devices.
- Monitoring the supply current consumption during switch-on and switch-off processes of DC motors and other consumers.
- Checking switches and circuit breakers using fast switching cycles.
- Measuring the response time of electronic switches.
- Calculating the power by simultaneously measuring voltage and current in one measuring module.
- Monitoring the current of photovoltaic modules and photovoltaic systems while environmental parameters such as temperature, global radiation, and other meteorological parameters are recorded at the same time.
- Measuring fast changes in power during load tests with rapid load changes.
Technical Features
- The digital ALMEMO® D7 measuring module uses its own integrated AD converter. The overall accuracy of the measurement is independent from the ALMEMO® V7 display unit/data logger. The measurement rate is solely defined by the integrated AD converter. On the ALMEMO® V7 measuring instrument all D7 measuring plugs work in parallel at their own measuring rate.
- Dynamic measuring signals are measured by the ALMEMO® D7 measuring module at a fast conversion rate.
- The ALMEMO® V7 measuring instrument saves the measured values, and the measuring software WinControl will display them graphically.
- The maximum, minimum, and average values can be calculated by measuring functions in the measuring device or in the measuring software.
- The measuring input is overvoltage proof and galvanically isolated from the ALMEMO® V7 measuring device.
