Paid on delivery
I am in need of a power supply expert to assist me with a project. The specific expertise I need is Power Supply Design, and I already have a schematic prepared for the project. I am looking for an engineer who is available to work on this project remotely and support me for a solution to fix the identified problem.
Attached documents:
1. Schematic PSU with SMR20.8/10111
2. Datasheet SMR20.8/10111
3. Schematic2 to be used with connected ESP32-S3 and Display
4. Oscillograph records referred to schematic2 (Channel1: VCC_IN, Channel 2: +3.3V, Channel 3: VCC)
5. I5 conducted radio frequency report
The product (room controller) has failed the requirements for the CE certification especially in "I5 conducted radio frequency". The expert should have good knowledge in power supply design and CE certification tests.
