A range of moulded case high accuracy universal DC or AC “CT” style current transducers, any AC current measured can be on a frequency range of between 20Hz and 6KHz. As would be expected of a product of this type and specification the measurement technology is TRMS. The output requires a 24VDC auxiliary supply, generating a 4-20mA output proportional and linear to the primary range of the transducer. Measurement ranges of between 0-50 Amps and 0-750 Amps are available in two frame sizes.

These products are particularly relevant with the growing prevalence of DC systems such as in the telecommunications, railway, and renewable energy sectors. Likewise the wide frequency range enables these products to be very suitable for distorted wave form scenarios, 400Hz systems and applications using VFD’s.
