Overview

The Littelfuse TCSA10 AC Current Transducer is a high-precision, loop-powered current monitoring solution engineered for industrial environments where accurate AC current measurement is critical. Designed as part of the TCSA Series, this transducer provides a linear 4-20mA output directly proportional to the RMS AC current flowing through its onboard toroid, enabling seamless integration with PLCs, meters, and other control systems. With factory-calibrated ranges from 0-5A to 0-50A, the TCSA10 is specifically configured for 0-10A monitoring, offering exceptional accuracy and reliability in applications requiring precise current tracking. Engineered for versatility, the TCSA10 operates on a 10-30VDC power supply, making it compatible with a wide range of industrial control systems. Its loop-powered design eliminates the need for additional power sources, simplifying installation and reducing system complexity. The transducer’s output is factory-calibrated so that 0 amps corresponds to a 4mA signal and full-scale current (10A in this model) produces a 20mA output, ensuring consistent and repeatable measurements across varying load conditions. For applications requiring monitoring of higher currents, the TCSA10 can be paired with an external current transformer (CT). By selecting a 2VA, 0-5A output CT rated for the desired current range, users can extend the monitoring capability up to 1200A AC. This flexibility makes the TCSA10 an ideal choice for power distribution systems, motor control panels, and industrial automation where both low and high current measurements are required. The TCSA10 features zero and span adjustments, allowing for minor field calibration to compensate for installation-specific variations or system drift. This ensures long-term accuracy and reduces maintenance requirements. Additionally, the transducer provides complete electrical isolation between the sensed current and the control circuit, enhancing safety and protecting sensitive downstream equipment from transient events or faults. Industries such as manufacturing, energy management, HVAC, and water treatment rely on Littelfuse transducers for their robust construction and dependable performance in harsh environments. The TCSA Series, including the TCSA10, is trusted by engineers and technicians for applications in motor protection, load monitoring, energy auditing, and process control. With a reputation for quality and innovation, Littelfuse delivers solutions that meet the demanding requirements of modern industrial systems. Whether deployed in new installations or as part of an upgrade to existing monitoring infrastructure, the TCSA10 AC Current Transducer from Littelfuse provides a cost-effective, reliable, and accurate method for measuring AC current. Its compact design, easy integration, and compatibility with standard industrial protocols make it a preferred choice for professionals seeking to enhance operational efficiency and system reliability. For custom current ranges or specialized applications, Littelfuse offers engineering support and custom product solutions to meet unique project requirements.
