Current Sensors datasheet and documents for CR4220S-30
Current Sensors Overview
The CR4220S-30 is a loop-powered AC current transducer manufactured by CR Magnetics Inc. It features a split-core design for non-intrusive installation and measures an input current range of 0 to 30 A AC. The device provides a standard 4 to 20 mA DC output signal with an accuracy of ±1%. It operates on a 24 V supply voltage and supports frequencies from 50 Hz to 400 Hz. The unit functions within an operating temperature range of 0°C to +60°C.
Current Sensors Feature Summary
- Split-core construction enables installation without breaking the primary conductor circuit.
- Loop-powered architecture eliminates the need for a separate power supply source.
- Provides isolated 4-20 mA DC analog output for precise current monitoring.
Current Sensors Applications
- Industrial motor control systems
- Power distribution panels
- HVAC equipment monitoring
Current Sensors Procurement Notes
Verify that the specific suffix 'S' denotes the split-core variant, distinct from solid-core models like the CR4220-30. Confirm the required input current rating matches the 30A specification. Ensure the application frequency falls within the 50-400 Hz operational range. Check that the ambient temperature remains within the specified 0°C to +60°C limits for reliable performance.
Current Sensors Selection Notes
Select this model when non-invasive monitoring of alternating currents up to 30A is required. The split-core design is essential for retrofitting existing busbars or cables. Ensure the downstream system accepts a 4-20mA loop-powered signal. Consider the physical aperture size of the split core against the cable diameter during mechanical integration.
Current Sensors Part Context
This component belongs to the CR4220S series of average RMS loop-powered AC current transducers. The series covers various current ratings from 10A to higher values. The 'S' designation specifically identifies the split-core configuration, differentiating it from solid-core alternatives in the manufacturer's product line.
Current Sensors Replacement Considerations
The CR4220-30 is a related solid-core model but lacks the split-core feature. Verify if the installation environment allows for conductor removal before considering solid-core substitutes. No direct cross-model equivalents are confirmed in public documentation.
