Aim Dynamics offers a wide variety of current sensors (also called current transformers or CTs). To help you find what you’re looking for, we’ve broken them down into these categories:
AC Amp Input -> 333 mV Output. These current sensors output 333 mVac at the rated current you select, e.g. 2000A/333mV. These customizations are available. All but the Rogowski coil kits are passive devices.
AC Amp Input -> 5A Output. These “true” current transformers output up to 5 Amps AC at the rated current you select. These are all passive devices except for the 5A Rogowski coil kits, which require external power.
AC Amp Input -> 4-20 mA Output. These current sensors output a 20 mA signal at the rated current and 4 mA at zero. The split-core current sensors are passive but the 4-20 mA Rogowski coil kits require external power.
AC Amp Input -> DC Voltage Output. These current transducers output a DC voltage on the secondary corresponding to the current detected on the primary. These are passive current transducers.
DC Amp Input -> DC Voltage Output (Hall Effect). These hall effect devices output a DC/AC voltage corresponding to the DC/AC signal detected on the primary conductor. These are active devices (require external power).
DC Amp Input -> DC Amp Output (Hall Effect). These hall effect devices output a small amperage corresponding to the DC/AC signal detected on the primary conductor. These are active devices (require external power).
UL Listed Current Sensors. These sensors are UL listed, meaning that they are certified to be field-installed with UL listed meters (or other equipment) and do not require calibration. These sensors adhere to the highest possible safety and reliability standards available.
Revenue Grade Current Sensors. These current transformers are required in order to perform any billing-related activities such as submetering. Whereas most current sensors sold by Aim Dynamics are 1% accurate, these units are 0.5% or better (up to 0.2%). They also have better low current sensitivity.
