ATH Series (patented) AC Current Transducers are the latest innovation from NK Technologies. Monitoring the current or power controlled by silicon-controlled rectifiers (SCRs) can be a challenge, especially the current used by heaters. When used to monitor zero-crossing (burst) fired SCRs, the ATH will provide an output signal directly proportional to the RMS amperage.

ATH Series Time Proportioned

Operating Instructions

Zero-crossing fired controls allow current to flow to the circuit for as short of a time period as one cycle, and off for several cycles. Most current sensors will not work well when there is no current present. This capability is important in case a heating element fails but the process continues operating, which could result in scrapped material.

AC Current Transducer Applications

  • Electrical Heaters
    • Faster response than temperature sensors.
    • Simplest method to monitor pulsed wave forms.

ATH AC current transducers will produce a signal proportional to the current used even when the controller is supplying power in one cycle increments. This is quite common as the "burst-fired" zero crossing witching method produces less harmonic distortion than phase-angle fired controls.

AC Current Transducer Features

  • Industry Standard Outputs
    • 4-20 mA, 0-5 or 0-10 VDC.
    • Compatible with most automation systems.
  • External Powered
    • Split-core models available powered with 24 VAC or DC.
    • Solid-core models powered with 24 VAC or DC or 120 VAC.
  • Factory Calibrated - No need for zero and span adjustment potentiometers.
  • RMS Output - Accurate measurement of sinusoidal or pulsed current wave shapes.
  • Built-in Mounting Feet - Simple, two-screw panel mount or attach with optional DIN rail brackets.
  • Designed for UL, CUL and CE Approval - Accepted worldwide
