How to control the HV converter with analog voltage signal?

The HV converter require 24V power supply and some analog voltage signals. I connect two 0~10V voltage signals to the pin of HV converter, 10HVA24-N1. However what I get from the output of HVA is 0V. Is there any thing wrong with my wiring?

Pin 12 is the current monitor output. It will output a voltage that's proportional to the HV current being supplied by the module. Hopefully there's enough resistance in series with the output that you…

So it looks as if your power supply thinks it is working. How is you divider working - (diagram) - its a strange co-incidence that 100uA into 0.63M would give excatly 63V. Your power supply max output…

Interesting device. Reading through the app note that is available on the manufacturer's website I noticed that pin 11 can be driven by TTL. The app note suggests that the level on pin 11 must be at least…

Thank you for reply. I provide the pin11 and the pin6 with 10V for enable or 0V for disable, while pin2 and pin6 with a step voltage between 0 and 10V.
Don't worry, the TTL can afford 10V.

What are you doing with the current-limit programming (pin 13)? If that input is arranged like the voltage programming, it will default to zero without anything driving it.

I just finish a test today, and the pin12 voltage is controlled with an additional 10V AO, but the HVA output is 0V. Interestingly, when my AO is connected to pin12, even though I program the AO to be 10V, the actual measurement shows 0V. And once I remove pin12, my AO can be detected as 10V again.

Pin 12 is the current monitor output. It will output a voltage that's proportional to the HV current being supplied by the module. Hopefully there's enough resistance in series with the output that you haven't damaged it by back-driving it with a voltage.

The programmable current limit input is pin 13.
