| Microwave oven - What kind of DC/DC Converter am I looking at? |
| (1/1) |
| JannB:
Dear community, roughly one year ago I tore down an old microwave oven. Sadly I did not make any pictures of the whole oven (e. g. the type plate). The part of interest is a DC/DC converter populated on one of the PCBs I salvaged for later use. The information I have are the following: Typ / Art.-Nr.: ETXMJ197X1BG Input: ~ 325 Vdc Output: DC 12 V and DC 30 V What I want to know #1: Manufacturer #2: Dataseheet (Rated power, line regulation, load regulation, etc.) #3: Price / Value I attached serveral pictures as well as the service manual for a similar microwave oven. The part of interest is referred with IC10. Unfortunatele the schematics are not searchable so you have to manually scroll to page 28 / chapter 19 to find the converter at the top middle. I tried to find this part at serveral venders without success. On mouser.com I get mostly open frame ones like: RECOM Power RACM30-12DK/277/OF |

Manufacturer is Matsushita / Panasonic. https://www.partmaster.co.uk/images/mediator/121/av359wb.pdf (page 28) https://fcgresources.blob.core.windows.net/fcgpdfs/ED/00230.pdf (page 28) https://www.sm.azhand.co/ServiceManuals/KA/Microwave/NN-C784M(PTE).pdf (page 33) https://www.sm.azhand.co/ServiceManuals/KA/Microwave/NN-C784MF%28TTE%29.pdf (page 31) https://www.commentreparer.com/doc/34435/panasonic-nn-l750wb-nn-l760wb-pdf.pdf (page 92) |

I can at least help with the Manufacturer Logo: https://logowik.com/matsushita-logo-vector-36730.html That distinct M stand for Matsushita. Googling Matsushita ETXMJ197X1BG returns a couple of service manuals like this one, listing the component: https://www.manualslib.com/manual/2800853/Matsushita-Electric-Nn-V688w.html#manual So it's a custom part made internally, there will very likely be no public specs available. |
