General Characteristics:

The ECOMeter is a meter device which measures the consumed and regenerated active or reactive energy of a traction unit on one hand, and allows transferring information about the line voltage and the line current to the traction control unit (TCU) on the other hand through an expansion box (ECOBox).

The device provides the detection of the type of catenary voltage system. It can be used on railway vehicles which operate in AC 25 kV 50 Hz, AC 15 kV 16 7 Hz, DC 3 kV, DC 1,5 kV and DC 750 V voltage systems.

The device provides a digital fiber optic communication to the expansion box in order to elaborate and convert the measured data according to the requested traction control unit interface with a negligible delay time.


The line voltage and the line current are measured and the energy value is calculated in compliance with EN 50463-2.

According to EN 50463 these functionalities are called voltage measurement function (VMF), current measurement function (CMF) and energy calculation function (ECF). The combination of these three functions is called energy measurement function (EMF). All these functions are integrated in the device.

The energy data is transferred via a digital interface to a data handling system (DHS) to create and storage the Compiled Energy Billing Data (CEBD).

Available options:

  • 1 O.F. Communication
  • 1 RS485 high speed digital sensor
  • 1 RS485 for TCU
  • 1 Ethernet communication
  • 6 Digital outputs configurable

Environmental Performance:

The device is suitable for railway rolling stock application, designed to be installed on the roof close to the pantograph.

The device is compliant with all regulations of the rail market. All the components are homologated for the industrial temperature range (from -40°C to +85°C - Class OT4 - EN 50125-1) and ensures proper function in the worst environmental conditions.

Electrical Performances:

The main feature of the device is the high accuracy in measurement and the high insulation degree between Low Voltage and High Voltage side.

The device is characterized by very low energy consumption and the auxiliary power supply nominal range is 24÷110 Vdc.

The ECOMeter accuracy is 0,5R for current and voltage measurement according to the standard EN50463.
