The CYVJ31/41 Series (Average RMS) and CYVJ31A/41A Series (True RMS), Voltage AC Sensors/Transducers are targeted for Measurements of three phase AC voltages. The relation between the output (DC voltage or current) and the input voltage (RMS) is linear. CYVJ31/41 Series can measure the average RMS of AC voltages and applied to long time monitoring of harmonic voltages.

The CYVJ31A/41A Series (True RMS) are especially for applications to monitoring of three phase AC voltages, the waveform of which is not ideal sinusoid. These transducers are accurate and ideal for measurements and monitoring of chopped waveform drivers and quickly varing motor loads etc.

The CYVJ31/CYVJ31A are used for 3-phase 3-wire AC networks/systems, while the CYVJ41/CYVJ41A
are for 3-phase 4-wire systems.
