The VariTrans P 42000 TRMS isolation amplifiers have been specially conceived for measuring high voltages up to 3600 V AC/DC. 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.
