25A AC Solid State Relay Design

@tshibsamuel477

Hi there, I’ve carefully read your project description, and I can help design a compact AC solid-state relay for pump loads, including opto-isolated control, LED status indication, zero-cross or non-zero-cross switching evaluation, PCB layout, BOM, and thermal analysis for 25A continuous operation. I’m Samuel Tshibangu, a mechatronics engineer with hands-on experience in power electronics, AC switching, opto-isolation, PCB design, thermal calculations, protection circuits, and industrial control hardware. I’ve already worked with SSR-style designs, TRIAC/SCR switching, MOSFET drivers, heat-sink selection, fusing considerations, and mains-rated PCB layout. I can deliver the schematic, fabrication-ready PCB files, verified BOM, thermal report, and a short application note for wiring, protection, and pump-duty testing. Feel free to send me your preferred enclosure/mounting style and pump specifications, and I can start right away. Best regards, Samuel Tshibangu

Hi There! As you can see in my portfolio on my profile, I have extensive experience designing PCBs and mass production equipment, just like you need. I can handle your project. I apologize for the simple proposal; I know you're probably tired of reading AI-generated proposals, and I'd rather not waste time on that. If you're interested in working with me, send me a message and we can work out the details! I already have a project for an oven created, in which I made my own solid-state relay to handle a load of about 5kW Best Regards!

I understand that you need a compact and reliable AC solid-state relay specifically tailored for pump loads, which is critical for ensuring efficient operation and longevity. With 12+ years of experience in power electronics design, I have successfully developed solutions that balance performance and reliability. My expertise includes designing circuits with full opto-isolation and zero-cross switching to minimize inrush currents, which is essential for motor-driven applications. I am proficient in creating detailed schematics, PCB layouts ready for fabrication, and comprehensive thermal analyses. I can provide verified BOMs with readily available components from mainstream suppliers. To ensure your project meets industry standards, my deliverables will include everything from schematic designs to application notes detailing wiring and startup testing. Additionally, my understanding of technologies like AWS can help optimize any future integration needs. Could you please clarify the preferred mounting method based on your thermal calculations?

With my background in IoT and embedded systems, I have honed my skills to produce reliable and efficient hardware solutions tailored for automation, sensor interfacing, motor control, and IoT-driven tasks. This project requires a designer who understands the delicate balance between size, power, and performance - qualities that I possess. My experience spans across building clean and scalable designs for BLDC motor control, wireless communication, digital electronics - all of which are essential in the creation of your solid-state relay. From developing the schematic with accurate component values to designing the PCB layout using Gerber, drill files, assembly drawing for easy fabrication – my commitment to delivering well thought-out solutions is unwavering. In addition to providing verified BOM with readily available part numbers from mainstream suppliers and a thermal analysis showing precise heat-sink selection with expected junction temperatures at 25A continuous, I will also furnish you with a detailed application note highlighting recommended wiring, fusing options as well as testing procedures for your specific pump duty needs. Let me put my skills to work on this project for you; together we’ll achieve great success!
