SCT013-RJ45-10

Current Sense Transformers Overview

The PowerUC Electronics SCT013-RJ45-10 is a split-core current transformer designed for non-invasive AC current measurement. It features a rated input of 10A and an output ratio of 2000:1, producing a 5mA output signal. The device operates within a frequency range of 50Hz to 1kHz and supports a maximum working voltage of 660V. Its compact design includes a 13mm x 13mm opening size, allowing it to clamp around conductors without disconnecting wiring. The unit utilizes a free-hanging in-line mounting type and incorporates RJ45 connectivity for standard interface integration.

• Ferrite core material ensures stable magnetic coupling for accurate sensing
• Compact physical dimensions facilitate integration into space-constrained monitoring systems

Current Sense Transformers Applications

• Building energy management and power monitoring systems
• Smart home automation and load detection circuits
• Industrial equipment current sensing and protection
• Energy efficiency analysis and data logging devices

Current Sense Transformers Procurement Notes

Verify the specific output specification (e.g., 5mA vs 1V) required by your downstream ADC or amplifier circuit, as the SCT013 series offers multiple variants. Confirm that the 10A rating aligns with your maximum expected load current to maintain linearity within the specified ±3% non-linearity tolerance. Ensure the conductor diameter fits within the 13mm x 13mm aperture. Check compatibility with the RJ45 pinout configuration used in your system design.

Current Sense Transformers Selection Notes

Select this model when a 10A rated input is necessary for low-current AC monitoring applications requiring non-invasive measurement. The RJ45 interface simplifies connection compared to bare wire outputs, reducing assembly complexity. Consider the 50Hz-1kHz frequency response to ensure suitability for standard mains frequencies and harmonic analysis. Evaluate the 2000:1 ratio against your signal conditioning requirements to determine if additional amplification is needed before processing.

Current Sense Transformers Part Context

The SCT013 series represents a family of split-core current transformers developed by YHDC and distributed by PowerUC Electronics. These components are widely recognized for their ease of use in retrofitting existing electrical installations. The RJ45 variant specifically addresses the need for robust, repeatable connections in automated testing and permanent monitoring setups, distinguishing it from models with exposed leads.

Current Sense Transformers Replacement Considerations

Direct substitutes include other SCT013 variants with matching 10A ratings and RJ45 interfaces, such as the SCT013-RJ45-100-50 if higher current capacity is acceptable. Verify that replacement units maintain the same 2000:1 ratio and 13mm opening size to ensure mechanical and electrical compatibility.
