I'm using the AMC1100 Isolation Amplifier for DC Voltage sensing,
I need to design the Circuit suitable for Insulation resistance at 2000V, With shorted the all terminals with body.
If I use the primary side voltage from my SMPS the Insulation resistance value was very low, and spark will occur. I tried the Zener based high side supply but Burdon was very high.
Suggest the power supply requirements.
