I ask not about component resp. part numbering like Q1, D1, R1, C1, L1.
Also not about RU stamp (a type of safety certification mark issued by UL Solutions) - go to

It's about numbering related to the printed circuit board itself.
I want to find out the actually manufacturer with help of these amount of numbers for those cases, where I don't get technical manuals when contacting the brand that is to read outside of the envelope.
The attached image show the PCB markings of an "Ultimate Speed Battery Charger" - German's model "ULGD 5.0 D2" (2516) - go to

I guess, a lot of other models/brands use an identical PCB, made in China.
For this PCB charger unit I need a schematic diagram, that isn't available from the German distributor.
How can I identify the manufacturer based on these numbers?
Thank you very much for an information so as posting appropriate URL's concerning this.

P.S.: the silver heatsinks and the electrolytics close to the heatsinks runs very hot while operation without cover (approximately 100-110 °C).

It was bought from Lidl. Authorized service-center is cmc.creative.de in St. Ingbert in Germany.
Schematic will not be published from there.
If I know the actually manufacturer in China maybe I will receive a schematic after sending an email.
Hence the basic question in the header, since one has the problem of not getting a circuit diagram resp. schematic with many devices these days, where the actual manufacturer is unknown.

The supply chain for these cheap products can be quite complex with agents, ODMs, contract manufacturing in the picture. Even if the party you bought it from has the schematic, they may not even be authorised to release it to you because the design is someone elses IPR.
Of course someone somewhere has a schematic for this type of cheap product, but I would never ever count on being able to get it. If you want/need that kind of assurance, buy from a known source where they have control over the design and the supply chain. That might not be how it should be, but that is usually how it is - and yes it will typically cost you more.
