Re: Trouble with Daker DK 3000 UPS
it's TO-220-2L part, 8 A/1200 V, you should find it easily

If anyone also knows the value of capacitor C17, that would be a very helpful addition.
This is the input power board of the UPS I’m referring to.Comment

In parallel, they read 24v, but within 24 hours, the meter on the front of the unit dropped from 4 to 3 bars on the battery charge indicator.

I quickly removed everything... -
