DLA1500i misbehaving

[Anonymous user]

I have a DLA1500i similar to SUA1500i I have been told.

I worked fine for years, apart from need battery replacing every 2/3 years it was just fine. But now it's not working as expected, aproximatly 2 out of 5 power outages it shuts itself down and drops the load. I saw it happening once, heard it beeping with the overload light on, then it turned down right after...

The load is about 20%(one light on) so I don't think it's overloaded.

Any idea about what could be causing this?

Control board defect, replaced all the eletrolytic capacitors except the big one 2700uF 40v and it's working fine now.
