Power Transducers measure 3-phase wattage consumption.
Press Release Summary:
Feb 25, 2014 - Housed in compact DIN mounted case, APT Series measures 3 phases of current and voltage and produces analog signal proportional to watts used. Monitor uses current transformers to measure amperes, and line voltage connects directly to transducer, up to 600 Vac. Transducers can be configured to accept 5 A secondary current transformers or ProteCT™ low voltage output sensors. Equipped with finger safe terminals, units are externally powered and offer 4–20 mA, 0–5 Vdc, or 0–10 Vdc output.

Measure Three Phase Wattage Consumption with the New APT Power Transducer from NK Technologies
Press release date: Feb 19, 2014
SAN JOSE, CA – NK Technologies introduces APT Series Power Transducers. The APT measures three phases of current and voltage and produces an industry standard analog signal proportional to the watts used. The monitor uses current transformers to measure the amperes, and the line voltage connects directly to the transducer, up to 600 VAC. By comparing the instantaneous current flow with the circuit voltage, the power factor, whether leading or lagging, allows the APT transducer to produce a signal directly proportional to the wattage used. The APT power transducer can be configured to accept 5 A secondary current transformers, or NK Technologies’ ProteCT™ low voltage output sensors. Either type of current sensing will produce an accurate output signal to help identify areas of excessive energy consumption and allow intervention to reduce demand.
“In many applications, monitoring power usage produces a more accurate result than measuring current use alone,” explains Philip Gregory, President, NK Technologies. “This accuracy makes APT Power Transducers idea for many applications including plant energy management, conveyors and pump monitoring. It’s been used to measure the power usage of a single piece of equipment, an area of a plant, or the entire facility. It can detect conveyor jams and overloads, and check that belts are loaded properly. The APT can also detect dry run from clogged pump intake or discharge lines and monitor impeller cavitation and bearing wear.”
APT Power Transducers are externally powered and offer 4-20 mA, 0-5 VDC or 0-10 VDC output. They are housed in a compact DIN mounted case with a low profile that reduces the need for large cabinet depth requirements. Their finger safe terminals are clearly labeled for quick installation.
