Current Sensors datasheet and documents for CR4420S-25
Current Sensors Overview
The CR4420S-25 is a split core average RMS AC current transducer manufactured by CR Magnetics Inc. It provides a calibrated DC output proportional to the AC current input, with an input range of 0-25A and a 4-20mA output signal. The device operates on a 24VDC supply with a maximum supply current of 45mA. It features ±0.5% accuracy, a response time of 250ms, and supports frequencies from 50Hz to 400Hz. Designed for bidirectional measurement, it mounts via DIN rail or panel installation in a module package.
Current Sensors Feature Summary
- Provides calibrated DC output proportional to AC current input
- Split core design allows non-intrusive installation around conductors
- Bidirectional sensing capability for positive and negative current flow
Current Sensors Applications
- AC power monitoring systems
- Industrial process control loops
- Energy management metering
Current Sensors Procurement Notes
Verify that the specific part number suffix matches the required current rating (25A) and output type. Confirm supply voltage requirements align with the 24VDC specification. Ensure the split core aperture size accommodates the target conductor diameter for proper magnetic coupling.
Current Sensors Selection Notes
Select this model when a 25A AC input range is required with a standard 4-20mA analog output. Consider the split core form factor if existing wiring cannot be interrupted. Verify frequency compatibility within the 50-400Hz range for the specific application environment.
Current Sensors Part Context
This component belongs to the CR4420S series of average RMS AC current transducers. The series offers various input ranges, including 5A, 10A, 15A, 25A, 75A, and 100A variants, all sharing similar electrical characteristics and mounting options.
Current Sensors Replacement Considerations
Other models in the CR4420S series such as CR4420S-15 or CR4420S-50 may serve as alternatives if different current ratings are needed, provided the physical dimensions and pinout remain compatible.
