CTS Current Sensors: Precision Power Monitoring for Evolving Industries

What is a current sensor?


A current sensor measures the flow of electric current to help optimize system performance, safety, and energy efficiency. They allow us to gauge how much power various parts are using. Whether it’s tracking motor loads in EVs, managing power in data centers, or monitoring energy in solar arrays, CTS sensors provide high-accuracy measurements with minimal phase shift. 

CTS designs and manufactures high-performance Alternating Current (AC) and Direct Current (DC) sensors using advanced Hall-effect technology. Our solutions support a wide range of industrial, automotive, and energy applications – including but not limited to:

 

Application use:

  • Electric vehicles (EV), hybrid electric vehicles (HEV), battery electric vehicles (BEV), and plug-in hybrid electric vehicles (PHEV)
  • Data centers and power distribution systems
  • Solar energy and renewable power systems
  • Marine Power Systems
  • Telecommunications infrastructure and power backup systems
  • Electric aviation
  • Rail and metro systems

  • Industrial automation and heavy equipment

  • IoT-enabled electrical panels

  • Robotics and process automation

Busbar mounted current sensors

Busbar Mount Current Sensors

These sensors range from 250-1500 A and can be directly mounted on a busbar. A variety of customization options are available, such as calibration and analog output range. Our engineers can work with your team to create sensors that will fit within your application constraints. This line of sensing solutions can be as accurate as 1%.

Clamp-On Current Sensors

Our magnetic field concentrators are designed for non-intrusive and isolated measurements of electric currents up to 200A. Thanks to the clamp-on design, these contactless current sensors can be safely installed without the need to interrupt or cut the cable. They are comprised of a soft ferromagnetic shield featuring superior material characteristics such as high linearity and very low hysteresis.
