NK Technologies introduces the ATH Series AC Current Transducer. The ATH is specifically designed to monitor power controlled by phase-angled fired, burst fired or time proportioned silicon-controlled rectifiers (SCRs) in heating applications, without requiring an external current transformer or shorting blocks.

  • Patent pending Time Integration functionality incorporated in the ATH design 
  • Provides an output signal directly proportional to the RMS amperage to ensure accuracy regardless of the AC current wave shape
  • Sensor samples the AC current continuously, updating its own time base when the current returns to the load after a pause
  • Based on the magnitude of the burst and the time interval between bursts, the sensor output represents the amount of power used by the connected load
  • Ideal for monitoring variable frequency drive applications
  • High sample rate allows for a smooth and accurate output regardless of the distortion of the current wave shape created by the drive
  • Installs quickly and easily via a two-screw panel mount or with optional DIN rail brackets, or suspended from the conductor in any position
  • Available in three industry standard outputs: 4-20mA, 0-5 VDC and 0-10 VDC
