ES030-5 Delta Elektronika Power Supply schematic needed
(1/1)
hub:
My Delta Elektronika ES030-5 power supply was damaged during normal operation (continuous load about 60% max power for 2-3 hours).

I found several damaged components – transistor (desoldered), converter controller, passive components.
I would like to fix it, but I can't read the value of some elements. Does anyone have such a power supply and could read the values of the components next to the transistor? I searched for a schematic of the power supply, but to no avail. I asked the manufacturer, but he does not provide any service manual or schematic.
I attach a view of the power supply board.
cte:
ET has a circuit diagram, but it looks like a different revision:

Thanks for the schematic.
The diode in the SOT-143 package connected to the transistor gate (I read a part of the signature - JT) is probably BAS28. In the older version, it was 1N4148.
