| 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). https://www.delta-elektronika.nl/products/es150-series 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. |

ET has a circuit diagram, but it looks like a different revision: https://elektrotanya.com/delta_elektronika_es-030-5_0-30v-5a_labor-supplies_sm.pdf/download.html |

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. |
