ATH Series, Solid-Core AC Current Transducers
NK Technologies’ ATH Series
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. 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.
