Transducers enable true RMS measurement.

Knick have defined a completely new class of AC/DC transducers for true RMS values with the announcement of their series P 43000 TRMS AC/DC high voltage transducers. Input values range from 100 mA up to 5 A AC. They are output as standardized analog DC signals (0…20 mA, 4…20 mA, 0…10 V).

A rotary switch on the front facilitates comfortable, calibrated switching between up to 16 customized ranges. Traditional AC/DC transducers are very susceptible to errors due to their poor insulation and are only designed for pure sinewave measurement. The Knick P 43000 TRMS, however, has been developed to also accurately process distorted input signals. The highly accurate true RMS circuit converts signals with a crest factor of up to 5 in the frequency range of 40 Hz to 1000 Hz or 8 Hz to 400 Hz. The VariTrans P 43000 TRMS withstands working voltages up to 3600 V AC/DC and test voltages up to 15 kV. Protective separation of the input, output and power supply provide protection from electric shock up to 1800 V AC/DC according to EN 61140.

Knick's own TransShield technology facilitates an extremely compact, shielded design of the high-voltage transformers, allowing the VariTrans P 43000 TRMS to fit into a very compact, only 45 mm wide housing. Vacuum encapsulation provides maximum long-term protection against aggressive environmental influences, shock and vibration. In addition, VariTrans P 43000 TRMS transducers come with an integrated VariPower broad range power supply for supply voltages from 20...253 V AC/DC, which ensures maximum safety even in regions where auxiliary power is shaky.

Knick VariTrans P 43000 TRMS transducers come with a five-year warranty.
