Industrial Power Control PCB Design

Industrial 220V Power Supply & Machine ON/OFF Control PCB Design I am looking for an experienced Power Electronics / PCB Design Engineer to design a compact industrial power supply and control circuit that will work with our existing IoT device. Main Requirements - Input: 220–240V AC industrial supply - Provide stable DC power to our existing IoT device - IoT device will provide the control signal for Machine ON/OFF - Circuit must safely switch/control the industrial machine using an appropriate relay/contactor/SSR or other suitable solution - The machine load current will pass through or be controlled by the designed switching section - Proper isolation between high-voltage AC and low-voltage IoT electronics - Include necessary protection: fuse, surge protection, over-current/short-circuit protection, etc. - Design should be reliable, safe, compact, and suitable for industrial continuous operation Deliverables - Complete schematic - PCB layout - BOM with available components - Gerber/manufacturing files - Design calculations and component ratings - Connection/pin diagram for integration with our existing IoT PCB Please apply only if you have practical experience designing 220V AC power supplies, industrial switching/control circuits, and PCB layouts. We will provide our existing IoT device specifications, required DC voltage/current, and machine load information to the selected freelancer.
