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.
