NK Technologies APT-TH Three-Hole Power Transducer Series ×

600 V 3-Phase, 0-5 VDC, 24 VAC/DC, 2.0 Three-hole, Solid-core No external current transformers No chance for loose CT secondary provides added safety LED on base shows correct phase relationship match

The APT-TH Series Power Transducers monitor watt consumption of three phase loads. They provide an analog signal proportional to the active power consumed by the monitored load. The three current carrying conductors pass through the three windows of the top section and the matching voltage input at the terminals. The APT-TH is a one-piece solution for measuring power; no external current transformers are needed and installation is easy. The design of the APT-TH ensures that the monitor is always correctly orientated. If connected improperly by mismatching the current and voltage inputs, or placing a conductor through the sensing window back to front rather than front to back, the LED will change color from green to amber. The LED will also turn amber if the phase A conductor is placed through the phase B sensing window, or if power factor is lower than 0.50.

Current Transducer Applications

Pump Monitoring

• Monitor pumps to detect open intake or outflow lines, cavitation or failing bearings.

Grinding and Milling

• Measure wattage/horsepower to optimize feed rate.
• Detect broken or missing tools or drill bits.
• Detect when the tool contacts the material.

Equipment Monitoring

• Constant output proportional to wattage consumed can be compared with utility bills, providing a cost per hour or cost per operation of a machine or process.
