VT3-OL Three-Phase Voltage Transducers

VT3-OL true RMS voltage transducers monitor all three phases and provide individual phase outputs plus an average output. They help identify under-voltage, over-voltage and phase-loss conditions in three-phase equipment.

Select line-to-line ranges of 0–150, 0–300 or 0–600 VAC, or line-to-neutral ranges of 0–150 or 0–300 VAC. Output choices are 4–20 mA, 0–5 VDC and 0–10 VDC. The VT3-OL uses a 120 VAC power supply and mounts on DIN rail or a panel.

A built-in SPST phase-loss relay closes when voltage falls below the threshold for the selected range. Typical applications include motor protection monitoring, power-quality supervision and process control.
