High Voltage Transducer

VariTrans P 43000

The VariTrans P 43000 isolation amplifiers have been conceived for direct measurement of currents up to 5 A (DC). 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.


  • Universal high-voltage isolator for converting input currents up to 5 A
    to impressed ±20 mA, ±10 V or 4 ... 20 mA output signals
  • 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 <0.3 %
    • Cut-off frequency>5 kHz (low-pass filtering possible
    • Rise time T90 <0.1 ms
  • Tremendous flexibility thanks to:
    • Calibrated switching of up to 16 input/output ranges (working voltage up to 2200 V)
    • Up to 16 customer-specific measuring 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
  • Mechanically stable for operation on ships, trains, and vehicles
