High Voltage Transducer

VariTrans P 41000

The VariTrans P 41000 isolation amplifiers have been specially conceived for measurements of bipolar voltages from millivolts to volts. They reliably isolate high potentials at the input circuit.
The isolating distances are designed to withstand permanent voltages up to 3600 V AC/DC and fast transients up to 20 kV.
Protection against electric shock is achieved through protective separation according to EN 61140 between input and output and power supply. Specially designed for current measurements using a shunt resistor.


  • Universal high voltage isolator for the conversion of voltages,
    for example in shunt applications, ±60 mV to ±100 V into impressed output signals
    ±20 mA, ±10 V or 4 ... 20 mA
  • New TransShield technology allows for extremely compact modular housing
  • Working voltages up to 3600 V AC/DC
  • Protection against electric shock through protective separation up to 1800 V AC/DC according to EN 61140
  • Test voltages up to 15 kV AC
  • Outstanding transmission properties:
    • Gain error <0.1 %
    • Cut-off frequency>5 kHz (low-pass filtering possible
    • Rise time T90 <0.1 ms
  • Practically no influence from common-mode voltages:
    CMRR >150 dB
  • High immunity to transient noise: T-CMRR >115 dB
  • Tremendous flexibility thanks to:  
    • Calibrated switching of up to 16 input/output ranges (working voltage up to 2200 V)
    • Up to 16 customer-specific ranges
    • Broad-range power supply 20 V to 253 V AC/DC
  • Reliable function even with unstable supply
  • No damage in the case of erroneous power connection
  • Switchable models reduce variety of versions, thus saving storage costs
  • Robust thanks to vacuum encapsulation
  • Suitable for direct current rail systems up to 3000 V DC
  • Mechanically stable for operation on ships, trains, and vehicles
