TCS Series

Closed-loop current transducers engineered for railway traction and high-power conversion.

TCS is a compensated, current-output current-transducer platform developed for demanding railway environments. It is designed for accurate AC and DC current measurement, fast dynamic response, strong galvanic isolation and robust integration into traction converters, auxiliary converters, substations and other high-power systems.

Designed around railway traction requirements

TCS is positioned as a strategic ADISENS current-sensing platform for rolling stock and railway power-conversion systems, with emphasis on accuracy, fast response, environmental robustness and electrical isolation.

Closed-loop accuracyValidated references achieve < ±0.4% accuracy, with selected 2000 A versions at < ±0.3%.
Fast dynamicsResponse time below 1 µs and di/dt capability above 100 A/µs.
High isolationValidated dielectric strength from 6.0 kV up to 13.4 kV AC depending on configuration.
Harsh-environment operationOperating temperature down to −50°C and up to +85°C on the validated references.
Configure your TCS

Build a reference from your application requirements

Select the main electrical and connection parameters. The configurator identifies whether the combination matches a validated standard reference or requires ADISENS engineering review.

Engineering review may be required for non-standard configurations.Non-recurring engineering (NRE/NRC) charges may apply depending on the requested current rating, turns ratio, connector, mechanical adaptation, qualification or validation requirements. Any applicable engineering cost will be communicated for approval before development starts.
