APT-TH Series Power Transducer

The APT-TH measures active power in three-phase loads using three integral current-sensing windows and matching voltage connections. It provides a 4–20 mA or 0–5 VDC signal proportional to the selected full-scale kW range, without external current transformers.

Choose a 208, 240, 480 or 600 VAC monitored-voltage model and a compatible 0.5–200 kW range. The transducer uses a 24 VAC/VDC supply and mounts on DIN rail or a panel. Its indicator is green when phase relationships are correct and amber when the installation is mismatched or power factor falls below 0.5.
