Current Transducers accommodate 120 Vac power supplies.

Press Release Summary:

In addition to 120 Vac solid-core models for heater monitoring applications, ATH Series Current Transducers with Time Integration are available in solid-core or split-core 24 V models. Units provide output signal directly proportional to RMS amperage. Built in signal conditioning eliminates need for shorting block on output, optimizing safety over conventional current transformers. For installation, transducers feature 2-screw panel mount and optional DIN rail brackets.

Original Press Release:

Solid-Core ATH Series Current Transducer from NK Technologies Now Available for 120VAC Applications

SAN JOSE, CA — NK Technologies solid-core case ATH Series Current Transducers with Time Integration now accommodate 120 VAC power supplies for use in heater monitoring applications. ATH current transducers are also available in solid-core or split-core 24 volt models. ATH current transducers are compatible with most automation systems and are ideal for monitoring burst fired time proportional control of heating systems. The ATH series also feature a simple two-screw panel mount and optional DIN rail brackets for quick and easy installation.

These current transducers are factory calibrated and feature industry standard outputs. They provide an output signal directly proportional to the RMS amperage and are accurate even though there are periods of time when the heating circuit is intentionally off, using no power.  Their design enables the sensor to remain installed over the conductor while the heating circuit is powered or when it is being serviced, regardless of what may be connected to the output terminals and even when there is nothing connected. The built in signal conditioning eliminates the need for a shorting block on the output, vastly improving safety over conventional current transformers.

NK Technologies offers no-cost test and evaluation units to qualifying OEMs. Visit the Engineering Resources section of NK Technologies website for access to numerous application notes and a technology white paper on current sensing technology.


Founded in 1982, NK Technologies designed the first the low-cost solid-state current sensing technology that underlies the industry today.
