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.
