AC/DC High Voltage Transducer

VariTrans P 43000 TRMS

The VariTrans P 43000 TRMS isolation amplifiers have been specially conceived for measurements of bipolar currents ranging from milliamps up to 5 amps. 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 100 mA~ to 5 A~
    • 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 
  • Virtually 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 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
