We need a prototype of energy consumption device which would use current transformers and report output values via RS232.
The project should support up to 10 split core current transformers connected via connector to a main board. Sample CT values and send data in realtime to RS232.
It also needs to sample current voltage so the final energy consumption readings are accurate.
The board should be fairly simple with 10 connectors for CT, power connector and output RS232 connector.
The goal of the project is to get accurate readings on each current. It should support 16A and 32A split core CT. This is similar to [url removed, login to view] yet i need more currents. One prototype is validated we'd need about 20 of these broards initially.

Hi there! So, you need device just with sending data over RS232? Validation you provide after receiving the prototype? The bid include schematics, firmware and prototype with shipping through standard mail.
Hello, I am an embedded systems designer and developer and can design this current sensor with 10 inputs for you. Kindly contact for further conversation and award of project. Regards.
