The AC current and voltage transmitter is an instrument that can linearly scale the measured AC current and voltage and isolate and convert the output DC current or voltage. Equipped with corresponding indicating instruments or devices, the measurement and control of current and voltage can be realized in the power system circuit. The true RMS transmitter does not affect the accuracy with the waveform distortion, and is especially suitable for areas with severe waveform distortion.

It can be fixedly installed on a 35mm standard guide rail, and can also be used for screw fixing.
