Product environment

Sécheron possesses years of experience designing electrical safety products and solutions for railway DC traction power substations. Our know-how covers isolated amplifiers for current measurement.

Our ESTRA-MIU amplifier measures high DC currents in power distribution systems for public transportation networks. With its high-voltage isolation the MIU ensures the electrical safety of people and property.

Technical Data
  • Rated voltage up to 3’600 Volts.
  • Test voltages up to 10 kV AC (15kV for the fixed setting version).
  • Application: current measurement through a shunt resistor.
  • Measurement of bipolar voltages: input settable from 60mV to 5V.
  • Output settable signals: ±5 V, ±20 mA or 4 … 20 mA.
  • Power supply voltage from 24 to 230 VDC/VAC.
  • Protection against electric shocks through protective separation between input, output and power supply.
  • Protective separation up to 1800 V AC/DC according to EN 61140.
  • Designed to withstand permanent voltages up to 3600 V AC/DC and fast transients up to 20 kV.
  • Reference standards: EN 50121-5 when mounted in a cubicle.
  • Reference standards: EN 61326 class B (standard for isolators).
