I'm need a circuit designed, tested and gerber files for the following microcontroller based approach meeting performance specifications: 1. Scalable from 5-40A load current 2. AI/DSP for Fault Detection and Noise filtering 3. Optically isolated (5kV) 4. 3-32VDC trigger voltage (regulated on the input of the design) 5. 3-32VDC VCC input power (regulated in the input of the design) 6. Circuit timing based on load current (not AC line voltage). 7. RS422 / IEEE 4888 / RS 485 handshake for: a. detected fault diagnostics b. voltage / current monitoring 8. Power down (sleep) mode when not in use 9. 24VDC +/- 20% load voltage with 65 A current spikes Attached is the PCB size/envelope.

Hello, I think there is more work involved in this project than your budget allows for. However, if you are still interested, I will look deeper into this for you. I have a number of questions that I would need you to clarify in order to give you an accurate quote. Best regards, Paul Burger
