VT3-OS Three-Phase Voltage Transducers

VT3-OS true RMS voltage transducers monitor three-phase AC systems with individual outputs for phase A, phase B and phase C, plus an average output. They help identify under-voltage, over-voltage and phase-loss conditions.

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-OS uses a 24 VAC/VDC 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. Applications include motor and power-quality monitoring and process control.
