Current and voltage transducers

IAM transducers

IAM transducers measure currents and voltages in industrial and railway (fixed installations) electrical installations through very high insulation. The insulation level is designed for permanent voltages up to 4000VDC.

Current measurement

The IAM-C amplifies signal measured on a shunt (primary side) and supplies a up to 25 mA output signals on the secondary side. It measures bipolar voltages from a few tens of mV up to 2 Volts.

Characteristics

  • Operating with low voltage and low loss shunt (from 30mV). Current output signal ±20 mA or 4 … 20 mA
  • 2 independent outputs (IAM2 only) for simultaneous measurements with different scales
  • High accuracy < 0.2%
  • Bandwidth 6Khz (-1dB)
  • High galvanic isolation 18.5KVAC 1min (100% production tested)
  • Rugged construction for any type of application
  • Powered directly from the battery (16-150VDC)

Voltage measurement

The IAM-V is intended for measuring AC and DC voltages from a few tens of volts up to high voltage (3KV).

  • For direct voltage measurement from 100V à 4000VDC. Current output signal ±20 mA or 4 … 20 mA
  • 2 independent outputs (IAM2 only) for simultaneous measurements with different scales
  • High accuracy < 0.4%
  • Bandwidth 6Khz (-1dB)
  • High galvanic isolation 18.5KVAC 1min (100% production tested)
  • Rugged construction for any type of application
  • Powered directly from the battery (16-150VDC)

IAS transducers for railway embedded applications

IAS Measurement Transducers measure voltages and currents in railway embedded applications through very high insulation. IAS are products that can be verified and can be (re)calibrated. The high level of insulation is provided for permanent voltages up to 4000VDC. These products comply with rolling stock standards.
