Product environment

Sécheron TMS is a versatile Traction Measurement System for rail vehicles. It provides signals that can be used for voltage detection, traction control and protection, and energy measurement functions. The current product configuration ensures voltage measurement for 15 kVAC and 25 kVAC traction system supply voltages. It transmits safe, isolated, and accurate signals to a variety of on-board equipment.

The TMS is available on a stand-alone basis so that car builders and operators can install it on the vehicle roof. It can also be integrated into our smart, compact MODBOX® high-voltage enclosure with other high- and low-voltage functions for the electrical safety, measurement and control of the traction chain.

If you are looking for a more comprehensive solution, the TMS can also be delivered as part of the Sécheron Hasler Energy Metering System with REM102 energy meter including the Energy Calculation Function (ECF) and the Data Handling System (DHS).

All of our components and solutions are backed by Sécheron expert service during all phases of your project. Let us recommend the best solution to meet your needs. Whatever your choice, you can count on efficient support worldwide for the entire lifetime of your product.
