CST-1015

Overview

The CST-1015 is a current sense transformer manufactured by Triad Magnetics, designed for through-hole mounting. It features a primary current rating of 15 A and operates at frequencies between 50 Hz and 60 Hz. The device has a turns ratio of 1000:1 and a primary DC resistance of 40 Ohms. It utilizes a three-terminal PC pin configuration for board integration.

Feature Summary

• Provides electrical isolation while sensing high-frequency current signals
• Supports through-hole PCB mounting via three terminal pins
• Engineered for industrial applications requiring precise current monitoring

Applications

• Industrial power supply current monitoring
• Switch-mode power supply feedback loops
• Overcurrent protection circuit design

Procurement Notes

Verify the specific datasheet version with Triad Magnetics to confirm mechanical dimensions and thermal ratings. Ensure the application environment supports the specified operating frequency range. Confirm that the 15 A primary current limit aligns with system requirements before finalizing procurement.

Selection Notes

Select this component when a non-invasive current sensing solution is required for AC or pulsed DC signals. The 1000:1 ratio suits applications needing signal reduction for downstream processing. Verify that the 40 Ohm primary impedance does not introduce excessive voltage drop in the target circuit topology.

Part Context

This part belongs to Triad Magnetics' current sense transformer portfolio, which includes various models for different current ratings and core sizes. The CST series is distinct from their WSU wall mount adapter line, focusing specifically on board-mounted magnetic components for signal conditioning rather than power delivery.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Engineers should consult Triad Magnetics directly for cross-reference recommendations based on specific performance criteria.
