SPECIAL AC VOLTAGE TRANSDUCER
	SELECTION GUIDE M100-VS1 Suppressed zero voltage auxiliary powered M100-VX1 1 ph. aux. powered ave. sensing RMS calibrated M100-VX33 ph. aux. powered ave. sensing RMS TYPICAL APPLICATIONS The M100-VS1 is a self powered voltage transducer. The suppression allows the transducer to accurately measure a voltage system over a narrow band either side of a nominal voltage. The range can be between ± 10% to ± 30% which can be specified when ordering. Typical application is to display the voltage on an analogue meter with an expanded scale. This allows the user to read small changes in the voltage in a single or 3 phase system. The output could also be fed to a computer that could then control the voltage of the system, to ensure that it stays within the narrow band. The M100-VX1 and VX3 are essentially the same as the M100-VA1 and VA3, but they have auxiliaries which allow the working range to be 0-125% rather than 10-125%. Used where the average sensing of voltage is required from 0 to 125% of the nominal voltage. ORDERING INFORMATION Product Code Input Un Output Aux Freq.
