Transducers
AC Voltage Demand Transducers (Moderate Time Interval) [Insulated]
AC voltage demand transducers output DC current or DC voltage that is proportional to the
average value (demand value) of the AC voltage within a specified time interval.
Applications
Monitoring of voltage due to load fluctuation
For detecting abnormal voltages in devices such as small-scale generators
For preventing the detection of error due to flicker

Accuracy of time interval (to): ±20%
The accuracy of the time interval is the accuracy of the time at which
the output reaches a value corresponding to 95% of a fixed value
when input.
Error may occur when the waveform of the input voltage is distorted.
For example, when the third harmonic voltage is 15%, the error is approx. ±2.0%.

Manufacturable range
The time interval (to) refers to the time required for
an output (Io) to reach a value corresponding to 95%
of a fixed input value (I) when the input (I) is applied
continuously.
The output becomes substantially 100% at 3 times
the time interval (3to).

Note 1. For low-voltage circuits, grounding of the secondary side of the instrument voltage transformer is unnecessary.
