Hi Roger,

that's a great news. It's worth trying to test it with this model.

I wonder if other people have some more models that support "power on

My EATON 850 has passive cooling without a fan so passively cooled UPS
would also be something nice. Mine makes noise only when it is operating
during power outage. Otherwise it is totally quiet.

Best Regards,
