Features / Benefits

  • Suitable for energy measurement
  • Current loop transmission for noise immunity
  • External shunt to adapt current to consumption
  • Insulated input terminals for limited space
  • Safe against internal arcs
  • Expert customer support
  • Worldwide after-sales service

Our ACX-A and ACX-V series transducers measure voltage and current on board rail vehicles operating at system voltages of up to 4 kVDC. All products in the series are suitable for indoor installation. Both the voltage measurement and current measurement transducers are insulated from the catenary voltage. The output signals on standard versions can interface directly with our REM energy meters.

All products in the series are accurate enough to be used for the catenary Voltage Measurement Function (VMF) and Current Measurement Function (CMF) to EU standards for energy measurement on board rail vehicles.

The ACX-A and ACX-V products can be delivered as stand-alone devices. They can also be integrated into Sécheron Hasler Group’s MODBOX® enclosures, or with Sécheron Hasler Group’s comprehensive Energy Management System, which also includes the REM102 Energy Meter with DHS and DCS.

All of our products are backed by HaslerRail experts, who provide recommendations and support throughout the project lifecycle, and Sécheron Hasler Group’s worldwide network of service locations for assistance throughout the product lifetime.
