AC Current Sensors CS-450/475 & SC-550/575 |
|
The CS-450 / 475SC-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 continuousfeature three jumper selectable current ranges for the highest accuracy. All sensors are factory calibrated to ensure better than 1% accuracy. The CS-450the SC-550 are available with 0-5, 0-10 Vdc or 4 -20 mA output signal types. The CS-475the SC-575 feature a true RMS 4-20 mA loop-powered output signal. All models are CSA certified, UL approvedCE compliant.
