TIDM-1000: AC input and output issue

Hi team,

Here's an issue from the customer may need your help:

The AC input in datasheet is 400 VL-L 50 Hz, Output 700-V DC Nominal. Is derating possible like input AC 220VL-L 50 Hz, output DC 400V DC Nominal. And can it be adjusted by modifying the parameters in the program?

Could you help check this case? Thanks.

Best Regards,

Cherry
