POWER_TO_VOLTAGE

Two Oρamρs and inexpensiveIC multiplier provide output voltage directly ρroρortional to instantaneous power through load. Frequency response extends from DC to several kilohertz.Maximum load powerfor linearity is 2 kVA, with maximums of 400 V and 5 A for load voltage and current. Output voltage can vary from -10 V to +10 V depending on instantaneous polarities and magnitudes of load voltage and current. R1 determines current range, and R2 determines voltage range.-D.
