Hi, I looking for a pro, that already have a proven and tested design of small board that contains the following elements: 1. SMPS, wide input range (90-250)VAC, double DC output: 12V@ 2. Simple relays driver 3. switching relays for pole and zero (2 single pole relays (each relay holds 16A) OR 1 double pole relay (16A per pole) 4. zero crossing sensor: detector output -> microcontroller (GPIO, not ADC) You can find more details in the attached file. More information will be available the bidders. BR, [login to view URL]

Hi, We can design this hardware with a production cost of $US 2-3. You have to escrow the project cost. After we complete the project only then you have to release the payment. This is just to make clear that I am not asking for any advance payment. I have a 19yrs of design experience in Hardware,microcontrollers, firmware and power electronics. Thanks, Amit

Hi, we have experience in SMPS design and zero crossing which we used for switching IGBT and Triac lighting controllers. We would be able to fulfil your project specification if chosen.

We implemented an I2C converter board for an embedded C board. The project seems similar. Can be done in shorter span of time if you provide us the details.I you require, we shall provide you the layout files also(Eagle) The prices of the micro SMPS has to be checked.
