Used to monitor power controlled by phase-angled fired, burst-fired or time-proportioned silicon-controlled rectifiers in heating applications, the NKT ATH Series AC current transducer requires no external current transformer or shorting blocks. A time integration functionality provides an output signal directly proportional to the RMS amperage to ensure accuracy regardless of the AC current wave shape. The 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. The transducer is available in 4-20 mA, 0-5 VDC and 0-10VDC outputs.
