EUROMeter FFF

General Characteristics:

EUROMeter FFF (Form Fit & Function) is a metering device which measures the train feed line voltage and allows transferring the information to the traction control unit (TCU) through an interface adapter device named ECOBOX.

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 750V voltage systems.

The line voltage is measured in compliance with EN50463-2.

In compliance to EN50463-1 the device implements the voltage measurement function (VMF).

The device provides high speed digital communication to the ECOBOX by optical fiber for long distance.

Available options:

  • 1 O.F. Communication
  • 1 Ethernet communication

Environmental performances:

The device is suitable for railway rolling stock application, designed to be installed either on the roof close to the pantograph or inside the vehicle in a cubicle.

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 -EN50125-1) and ensure 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 accuracy is 0,5R for current and voltage measurement according to the standard EN50463.
