The Demico AC Voltage Transducer provides accurate, affordable, true RMS monitoring of three phase electrical power circuits. Separate power supply input terminals allow an additional phase to be used for power, if desired. Each Voltage signal is processed through true RMS circuitry before being converted to a linear dc output current. A simple resistor from 0 to 10,000 ohms is all that is required to scale and interface to a standard RTU analog input. The transducer output’s galvanic isolation from the input terminals eliminates ground loops and ground referenced noise. Each transducer is isolation tested from input phase to input phase as well as input to output. The transducer will indicate properly up to 20% over the maximum range. The transducer is accurate to 0.25% over a wide temperature range for dependable data even in non climate controlled environments. Three conveniently located adjustments allow calibration in the field. Use this transducer for three phase circuits or three single phase circuits.
