CR5211S-30

Current Sensors Overview

The CR5211S-30 is a Hall effect, closed-loop, unidirectional DC current transducer manufactured by CR Magnetics Inc. It features a split core design for non-intrusive installation and measures direct current inputs ranging from 0 to 30 A. The device operates on a 24 VDC supply with a tolerance of +/-10%. It provides a proportional analog output voltage ranging from 0 to +10 VDC, suitable for driving loads with an impedance of at least 2 kΩ. This component is engineered for precise average DC value sensing in industrial control systems.

Current Sensors Procurement Notes

Verify that the application requires a split core configuration compatible with the specific conductor size. Confirm that the system power supply strictly adheres to the 24 VDC +/-10% specification to ensure proper operation. Ensure the downstream signal processing circuit presents a load impedance of no less than 2 kΩ to maintain output accuracy. Check that the current direction aligns with the unidirectional design constraints of the module.

Current Sensors Selection Notes

Select this model specifically for direct current measurements up to 30 A where non-invasive monitoring is required. It is suitable for environments needing isolated sensing without breaking the primary circuit. Consider the split core geometry when planning physical integration. Ensure the application does not involve AC or pulsed currents exceeding the device's frequency response capabilities.

Current Sensors Part Context

This component belongs to the CR5211S series of DC current transducers from CR Magnetics Inc. The series is designed to measure wide ranges of direct current using Hall effect principles. The CR5211S-30 represents the 30 A rating variant within this family, sharing common architectural features such as split core construction and analog voltage output characteristics with other models in the series.

Current Sensors Replacement Considerations

Direct substitutes within the same series include the CR5211S-20 (20 A range) and CR5211S-10 (10 A range) if lower current ratings are acceptable. Verify that any replacement maintains the split core form factor and identical electrical specifications regarding supply voltage and output load requirements.
