I am looking for a high voltage measurement module (1000V DC) that can be connected to the “e.bloxx A3-1 analog input” module. the analog input range is ±10V. can someone help me find the right part?
After looking in our system, I was unable to find anything similar to the e.bloxx A3 unit you referenced that could be used instead.
Technical reference number T4116487
I don’t want anything similar to e.bloxx A3. I want a high voltage sensor measurement that I can use the analog output from it to the analog input module that I have and read the voltage value.
The simplest approach would be to just use a few resistors to divide the HV by roughly a factor of 100. One would need to pay attention to the limiting element resistance figure, since 1 kV exceeds that of typical resistors by quite a ways. 490-18219-ND and 100KXBK-ND might make a suitable pair.
Depending on grounding arrangements, isolation requirements, and the output impedance of the HV source, this may or may not be a suitable approach.
If you are looking for a DIN rail type solution, it looks like the Verivolt ENTUBE SE (1000V 10V) (Digi-Key part number 1780-1159-ND) might do the job. It will take up to +/-1000V and scale it down to +/-10V.
They also make an isolated version, the ISOBLOCK V-1C (1000V 10V) (Digi-Key part number 1780-1049-ND). This one requires a power supply between 8V and 28V, whereas the ENTUBE SE (1000V 10V) is a passive device which does not require a supply, but which is not isolated.
thank you so much. your suggestions help a lot.
