CVT500, Current and Voltage Transmitter
- Measuring input for DC and sinusoidal AC signals
- Arithmetic average value measurement RMS calibrated
- Frequenca range 40...200kHz
Transmitters CVT500 convert current or voltage signals into proportional industry standard signals. Currents up to 5AAC/DC and voltages up to 400VAC/DC can be fed directly into the transmitter. For higher AC currents a current transformer respective for higher AC voltages a voltage transformer has to be fitted.
The transmitters are available in two versions regarding the supply voltage.
Please select the requested supply voltage when ordering.
