CTS designs and manufactures busbar current sensors with accurate monitoring, enhanced safety and  efficient power distribution.  Busbar current sensors are devices used to measure electrical current in busbar systems, which are conductors used to collect electric power from incoming feeders and distribute it to outgoing feeders. Efficient sensing for motor current is critical to electric vehicles (BEVs, HEVs, and PHEVs). 

The series CTS-CS-BAX-20 is a current sensing module from CTS Corporation, specifically designed for integration into electrical systems based on busbars. Utilizing Hall-effect measurements, this busbar mount current sensor will provide highly accurate and non-intrusive readings of both AC and DC currents up to 1500 A. The series CTS-CS-BAX-20 is available in four off-the-shelf versions, but can be customized to unique specifications as well. If a standard/off-the-shelf product does not meet the specs, we can offer a customized solution with CTS.

Busbars are used far and wide in all manner of electrical systems. Essentially serving as a central hub for multiple electrical connections, busbars offer advantages such as low electrical losses, high power density to size ratio design simplicity and easy installation and maintenance. Having an integral role in countless systems, distributing power from a central source such as a generator or transformer to multiple circuits, busbars should always be vigilantly monitored. Optimized current flow through these conductors will translate to an equally optimized performance of all sub-systems connected to them. And at the same time, sub-optimal performance at the busbar level will cascade throughout all adjacent circuits, potentially hampering multiple system functions severely. To ensure proper operation of busbar systems in the mid-to-high current range, CTS is launching the series CTS-CS-BAX-20, a range of easily installable and highly accurate busbar mount current sensor modules. CTS provide customized solutions to meet a wide range of performance needs based on our established modular design building blocks. CTS current sensors are accurate within ± 1% and solutions can be tailored to fit unique needs. Our Sensors provide a cost-effective solution for high-amperage drive motors, even with customized packaging and mounting options. Designed using Hall-effect technology, these sensors provide a consistent, high-performance signal in a lightweight, streamlined solution. Regardless of your busbar arrangement or other housing requirements, CTS engineers can build a sensor to exact specifications, guaranteeing that it will fit your needs.
