Three ranges per unit reduces inventory No field adjustment necessary, factory calibrated Average measurement is equivalent to True RMS  for pure sine waves for the CS-450 / SC-550 series. True RMS measurement for sine waves or variable frequency drives for the CS-475 / SC-575 series. Input / Output isolation via current transformer Solid-state reliability Small compact size Solid, reliable mounting method

The CS-450 / 475 and SC-550 / 575 series of AC current sensors are solid-state transducers that convert a primary circuit current to a proportional output signal. The sensors can monitor up to 200 Amps continuous and feature three jumper selectable current ranges for the highest accuracy. All sensors are factory calibrated to ensure better than 1% accuracy. The CS-450 and the SC-550 are available with 0-5, 0-10 Vdc or 4 -20 mA output signal types. The CS-475 and the SC-575 feature a true RMS 4-20 mA loop-powered output signal. All models are CSA certified, UL approved and CE compliant.
