Electrical power measuring circuit - has voltage and current input and output protection stages, and feeds voltage and current values to analogue multiplier

摘要

The circuit receives an input voltage or current via a voltage or current input protection stage and delivers its output via a voltage or current protection stage. The input voltage is fed to a voltage input module which prepares it for further processing and feeds it via a controller interface and mother board to an analogue multiplier. The input current is similarly processed and fed to the multiplier. The mother board is connected via a control and counter board, a summer amplifier board and via an analogue/frequency output of the multiplier to an instantaneous power and a total instantaneous power output port. USE/ADVANTAGE - For DC, AC and pulsating DC current. Provides more frequency outputs than conventional ones and has more rapid start-up.
