Design Electrical Circuit to Power a Laser Directly from 120VAC --

Hi, I am aware of some off the shelf solutions available. Also, i can design such a circuit with very small footprint. I would like to discuss further to understand your footprint limitations for circuit.

Hello there How are you? I am an electrical engineer who has enough experience in electrical engineering and embedded system design. I know you are going to develop the power circuit for a laser, I have done similar project before. I can help you with this project and can start the project right away. Regarding your project I have rich experience in this field, so I think this project is very suitable for me. Thank you Alexander

Hi, Can you give me your dimension constraints? I mean, There is lot of ways to convert 120VAC to 3VDC. And For your case, I will use simple small bridge diode(or even not use it), and add current limiting resistor to limit current drained to your circuit so it won't hurt laser led. we also have to discuss type of laser pointer you want to used, so I can use maximum performance of laser pointer without break it's limit. for sure this project can be finished in 1-2 days if we manage communication propperly. Best Regards, Rijal

Hi There, I am Shahbaz Ali. We will design the circuit and will do the prototyping to ensure flawless working. Once the Prototype is ready we will test it in heat chamber at different temperatures to ensure proper working and avoid thermal failure. After this we will test the circuit against 50,000 on/off cycles this will ensure immunity to any transients occurring while the power switch is turned on or off. Please feel free to contact us. Best Regards, Shahbaz. Summary of Test

I have very good experience to design high voltage power supplies up to 50KV for capacitor charging power supplies using soft switching topologies. I have work experience to design from few watts to KW range meeting all compliances like EMI/EMC and safety standards UL etc.

Hi, I can design this circuit for your application, I'll design, build and test the circuit before I send the design files to you. Do you have the datasheet of the laser diode that you plan to use? if you have any question please let me know.

hi there we are a team of electrical engineers. we have 8+ years experience in circuit design and pcb designs. we have designed many power supply circuits in the past and have very good experience related switching mode power supplies. let us know if you are interested we can discuss further. we will also provide 2 pcb prototypes in this bid

Hell I'm Mohamed Saeed. circuit design engineer. I have checked your job description and I'm ready to help you in your project.

Hello sir, I am a mechatronic engineer, professional at Circuit design and Power electronics. I am really can help you for your needs. I will finish that project perfectly and at less time you need, I am sure. I had done like that project before ,tell me to show you. So, contact me for more details, I am available from this moment . I trust that I will make you completely satisfied. Thanks

I am electrical engineer .I have lot of experience working with various employers globally. Can I do Circuit Analysis and design, Power System Analysis,DC/AC machines Electrical Distribution , translation and technical writer .i use Autocad,Matlab,Revit,Plc simulator, Pspice,word and excel.

I have used experience in desiging of OTDR experiment for students at uni of South Australia. So I kmow how a laser driving board works...Let me know further about your requirements. Thanks,!

I am an electrical engineer, MSC in applied mathematics, MSC in power systems, PHD. Control and automation. I can make your problem at any level, within my proposal, I can offer you additional extras. with 23 years of experience. I can make your proposal with all the details you need. I can improve your proposal, with a mutual agreement. I have worked as heads of automation engineers, processes in several machine design management companies and industrial production plants. other forms of optimization, improving the manufacturing process, etc., we can discuss the details of your needs in the chat. I have already done this type of analysis for this application the matlab, labview, and others. I'm interested in your project I can do your project Atte. ING. Luis Moreno

hello I'm electrical engineer and university laboratory researchers I'm familiar with power supply and power electronic I made that's many times in Univ laboratory you will be happy to work with me

i am a prefinal year student of B.E in Electronic and Communication.I abke to design a pcb for power supply and avr board.I will help to run your project successfully and make you successfull

I am having 3 years of experience in the design field. I have worked in power supply design also. so i am happy to do these kind of circuits. I can give you good quality design.
