§Small-sized plug-in transducer§
2-outputs type

AC Voltage Transducer
FWVT■ Application
Converts AC current in an electric power system intoa DC signal in proportion to input. With input andoutput insulated, the product offers full advantages intransmitting insulated signals between measuringsystems, cutoff of noise, protecting a control circuit froma sneak current, and transmitting an output signal
directly to a distant place. Because this transducer can
extract two insulated outputs, a single unit can docontrol and monitor. Up to 16 units can be housed in an
installation base.

■ Feature

29.5×76×125mm/180g
Compact and high withstand voltage.
Withstand voltage between input/output/auxiliary supply/outer case is AC2, 000V(50/60Hz) for 1 min..
Withstand voltage between outputs is AC500V (50/60Hz) for 1 min..
Constant voltage/current output type. No need to adjust the product if it operates
within load resistance range.
A LED can confirm status of electric power applied.
Zero/span of 1st and 2nd output can be adjusted individually. (±2% adjustable)
Because the device is RMS value operation type, it can also be used with adistorted waveform or a SCR waveform.
