Volt-Amp Controller with Safety Features

I am building an integrated volt-ampere meter that also serves as a protection and control module for a pump system. The unit must: • Measure voltage and current accurately while reacting instantly to high/low-voltage and over/under-current conditions (these three protections are the top priority)...
