As indicated by the name, current sense transformers detect (i.e., sense) electrical current and/or convert (i.e., transform) it into usable forms for various industrial and commercial devices. They find use in a wide range of instrument control and monitoring, switch-mode power supply control, and equipment feedback applications, including ones with demanding operating or environmental conditions. For this reason, they are available in numerous standard and custom designs and configurations to suit different requirements and restrictions.

Custom Current Sense Transformers From Triad Magnetics

 Triad maintains five standard current sense transformer lines, all of which can be modified to meet specific custom application requirements:

  • CST206/CST306 Series High-Frequency Current Sense Transformers: These transformers are suitable for operations involving frequencies ranging from 20 kHz to 200 kHz.
  • CSE5 Series High-Frequency Current Sense Transformers: These transformers are designed to monitor electrical currents from 250 kHz and up.
  • CSE Series Low-Frequency Current Sense Transformers: These transformers are engineered for monitoring current in low-frequency applications.
  • CST Series Low-Frequency Current Sense Transformers: These transformers are ideal for frequencies between 50 Hz and 60 Hz.
  • CST25 Series Current Sense Transformers: These transformers are designed to monitor electrical current in high-frequency applications, such as LED lighting systems and switch-mode power supplies.

In addition to our standard products modification services, we offer complete custom solutions to accommodate highly specific or unique applications. Equipped with extensive industry experience and an ISO 9001:2015 U.S. Design Center, our team has the knowledge, skills, and tools to provide a custom current sense transformer for virtually any customer application. At every stage of the production process—from design and prototyping to manufacturing and testing—we keep the customer’s specifications in mind to ensure the solution we deliver fully meets all of a customer’s needs.  

Some of the design options available for our custom current sense transformers include: 

  • Construction: open toroidal, severe-duty encapsulation, or custom encapsulation
  • Termination: PC mounts, flying leads, custom leads, connectors, or terminals

We can also design and build our transformers to meet various performance requirements (e.g., current ratio, output, accuracy and inductance) or accommodate extreme operating or environmental conditions.
