I'm looking for a circuit designer capable of creating a circuit to compensate for a --break-- of the 220v. The 220 volt arrives with an input of 2 milliseconds and then disconnects for 18 milliseconds. Is it possible to overcome? A 12 volt outlet would be good for us

YEs it is possible. I can suggest a circuit , you have to get the components and wire it up. What is the current drawn by your temperature sensor circuit?

Hi. Thanks for posting your project about a 12V circuit for a thermostat. Please find below a summary of my proposal. SCOPE OF THE WORK: If I understand correctly, you look for a circuit to feed a thermostat with 12V pulses of the specified timing and phase, while the contacts are wired to a 220V floor heater. In that case, I can design a simple 12V pulse generator, either self-timed or synchronized to the zero crossings of the Mains 220VAC. The synchronization is done by an opto-coupler. The pulses are generated with logic gates so there is no need to use a microcontroller. The entire board can include a 12V regulator or just an input for external 12V supply. DELIVERABLES: - Circuit diagram (.PDF) - PCB manufacturing files (Gerber, pick & place, drill list, etc.) - Bill of parts (.XLSX) with 3 vendor codes per part and confirmed stock. - 3D CAD model of the board (.STEP) - Render images of the board BACKGROUND: 11+ years of experience in hardware design, including: - Circuit design and simulation (Altium Designer) - PCB layout design, high-speed and multilayer boards - Managing PCB manufacturing, assembly, prototyping and global shipping - Programming in C, C++, Arduino, Python, Pytorch, NumPy Please check my portfolio with examples of past jobs. Hoping it will meet your requirements. Looking forward to helping you with this project. --- Best Regards, Gonzalo Perez, EE

Hi, Despite I am a beginer on freelancer.com, most of all I'm an EE Engineer with decades of experience in designing electronics circuit. Sure I can help you with your project. I've a question however. The 230V mains is 50Hz AC. You states that - for an unknown reason - the main voltage blinks 2ms ON ans 18ms OFF, that is at a 50Hz frequency. Is this synchronous of the 50Hz main frequency ? If yes, how is this phased? I mean is the ON phase in coincidence with peak main voltage? Regards, Jean-Paul PS: my bid assumes that I only deliver a validated schematics (i.e. not the circuit itself)

Ciao, Sono un ingegnere elettronico posso aiutarti a risolvere la tua problematica anche se non mi è tutto chiaro. In pratica la 12 volt DC che alimenta termostato deve essere dervita da una 220V in AC che ha un duty cycle del 10% ( 2ms on 18ms off) giusto? per cui ti occorre un trasformatore con raddizzatore e regolatore. Scrivimi cosi mi dai maggiori dettagli e valutiamo il da farsi e l'offerta economica. Grazie Manuel Chiumarulo

Hello, I am an Electrical Engineering student from Turkey. I started designing electrical circuits a long time ago. I have sufficient knowledge and experience for this task. I can draw a PCB, then you can order it from a PCB manufacturer like JLCPCB... They also provide PCBA service; so you can order the functional PCB directly.
