SWD insulation for 230V

We are developing devices which are supplied with 230V AC mains supply. The 3,3V supply voltage is made by a switching Power supply but is not potential-free to the 230V mains supply.

So we need insulation (safe separation according to VDE) between debugger and mikrocontroller. We need the insulation voltage below to fulfil the requirements:

4.240 VDC or 3.000 V AC for 1 minute

Segger has a SWD isolator, but it us not for hight mains voltages, only for removing GND loops.

Does anybody sells a SWD insulation for 230V? Or do I have to develop an interface? Does anybody has experience about this?

Best regards

Martin
