We are after an energy monitoring device. We need to measure a maximum of 32 amps @ 230volts passively using a current transformer. It needs to have multiple channel support, i.e. measuring 48 branch circuits in a distribution board. We are open to offers re design / programming / production. Initially we are after a system that will measure unto 48 circuits. This can be made up of 6 x 8way boards if needed. The output needs to be able to be queried via a HTTP get process or SNMP get request. The voltage will be regulated by a UPS system @ 230 volts.

We have similar kind of projects in past. We have made ups and voltage conditioners three phase where these kind of ampere meters have been used up to 35Amps with over current and over under voltage protection. Looking forward to hear more details from you soon.
