Secheron Voltage & Current Sensors
Sécheron offers on-board voltage and current sensors for Voltage and Current Measurement Functions (VMF & CMF). With its unique and simple architecture without software, TMS compact and lightweight AC sensor is a safe, accurate voltage and current sensor that railway car builders and operators can count on for their energy metering and vehicle protection needs.
For DC vehicles, Sécheron delivers voltage and current sensors with its DC circuit breakers enclosed in DC metal enclosures.
