AC/DC High Voltage Transducer

VariTrans P 41000 TRMS

The VariTrans P 41000 TRMS isolation amplifiers have been specially conceived for measurements of bipolar voltages ranging from millivolts to volts. They reliably isolate high potentials at the input circuit. Thanks to the true rms conversion in the transducer, even distorted input signals are captured correctly and output as so-called true rms values.

The isolating distances are designed to withstand permanent voltages up to 3600 V AC/DC and fast transients up to 20 kV.


  • Universal usability:
    • AC Input 60 mV~ to 10 V~
    • DC output 0 (4) ... 20 mA, 0 ... 10 V
  • 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 < 0.5 % with crest factor < 3
    • Gain error < 1 % with crest factor 3 ... 5
    • Response time T90 < 150 ms rising, < 300 ms falling
  • Practically no influence from common-mode voltages: CMRR approx. 150 dB
  • Tremendous flexibility thanks to:

    • calibrated switching of up to 16 input/output ranges
    • up to 16 customer-specific measuring ranges
    • VariPower 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
