I need ERICSSON BML 231 201 PSU modification detail
« on: October 30, 2018, 10:42:32 am »
Hi,
I have seen ERICSSON BML 231 201 PSU modifications on some of Indonesia's web pages "27V to>> 13,8V modification"
Do you have knowledge about model psu modification "ASTEC/EMERSON/ERICSSON BML 231 201"
I see some post-modification sales on some web resources, but I haven't found any details.
Examples;

If you have information about the modification I would like your help.

Best Regards
