CR4111-30

Current Sensors Overview

The CR4111-30 is a True RMS AC current transducer manufactured by CR Magnetics Inc. It features a single element solid core design with dual pass-through capability. The module provides two channels for bidirectional current sensing, supporting an input range of 0 to 30 Amperes AC. It operates within a frequency band of 20 Hz to 5 KHz and requires a 24 VDC power supply with +/-10% tolerance. The device includes integrated conditioning circuitry and demands an output load of at least 2K ohms.

Current Sensors Feature Summary

• Dual channel transformer-based sensing with integrated conditioning
• Bidirectional measurement capability for accurate AC current tracking
• Solid core single element construction for robust signal integrity

Current Sensors Applications

• Industrial motor drive monitoring
• Power quality analysis systems
• Battery management system testing

Current Sensors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct configuration. Confirm that the required output load impedance meets the minimum specification of 2K ohms for proper operation. Check compatibility with the 24 VDC power supply voltage tolerance limits before integration into the control circuit.

Current Sensors Selection Notes

Select this component when dual-channel bidirectional AC current monitoring is required within a 30A range. Ensure the application frequency falls between 20 Hz and 5 KHz. Consider the physical dimensions and mounting requirements for the dual pass-through module form factor compared to single-channel alternatives.

Current Sensors Part Context

This part belongs to the CR4111 series of current sensors from CR Magnetics Inc. The series includes variants such as the CR4111-20 and CR4111-50, which share similar architectural features but differ in their rated current capacities. The CR4111-30 specifically targets applications requiring moderate current measurement with high accuracy.

Current Sensors Replacement Considerations

The CR4111-50 serves as a higher capacity alternative within the same product family. Verify that the increased current rating does not compromise sensitivity requirements. Ensure mechanical fit and electrical interface compatibility remain unchanged during substitution.
