CR4460-30

Current Sensors Overview

The CR4460-30 is a two-element average RMS AC current transducer manufactured by CR Magnetics Inc. Designed for multi-point sensing, it provides a calibrated DC output signal proportional to the input AC current. The device features a 30A sensing range with ±0.5% accuracy and operates within a frequency band of 20Hz to 4kHz. It supports dual channels and offers bidirectional measurement capabilities. Power requirements include a 24V supply voltage with a maximum current draw of 90mA. The unit delivers a 40mA output current and achieves a response time of 250ms. It is constructed as a module suitable for DIN rail or panel mounting.

Current Sensors Procurement Notes

Verify that the specific part number matches the required 30A sensing range and 24V power supply configuration. Confirm that the bidirectional capability aligns with the application's current flow direction requirements. Ensure the 250ms response time is sufficient for the intended control loop speed. Check compatibility with existing instrumentation interfaces accepting the specified output signal type. Validate that the physical module dimensions fit the designated DIN rail or panel space constraints.

Current Sensors Selection Notes

Select this model when precise average RMS measurement of AC currents up to 30A is required. The two-element architecture distinguishes it from single-element variants like the CR4410 series. Consider the 20Hz to 4kHz frequency range against the system's operating frequency. The bidirectional feature is critical if reverse current flow must be detected. Compare the 90mA maximum supply current against available power resources in the control panel environment.

Current Sensors Part Context

This component belongs to the CR4460 Series of Average RMS AC Current Transducers. The series is designed to produce DC output signals proportional to AC input currents. It shares design characteristics with other models in the family, such as the CR4450-40, but differs in sensing range and element count. The series generally meets regulatory standards including UL 61010B-1 and IEC 61010-1.
