CS-1200-R

Overview

The CS-1200-R is a board-mount current sense transformer manufactured by Eaton Electronics Division. It features a non-invasive solid core design with through-hole termination for PCB integration. The component provides a current ratio of 200:1 and supports primary currents ranging from 4A to 40A. Key electrical specifications include an inductance of 89.7mH, a secondary resistance of 3.3 Ohms, and an operating frequency range of 20kHz to 100kHz. Physical dimensions are 17.15mm in length, 9.53mm in width, and a maximum seated height of 0.800 inches.

Feature Summary

• Non-invasive solid core construction for isolated current measurement
• Through-hole mounting style suitable for standard PCB assembly processes
• Wide operating frequency range supporting high-frequency switching applications

Applications

• High-frequency power supply current monitoring
• Switch-mode power supply (SMPS) feedback loops
• Industrial motor drive current sensing

Procurement Notes

Verify the specific datasheet version provided by Eaton or authorized distributors to confirm RoHS compliance status and lead-free characteristics. Ensure that the required current rating does not exceed the 40A maximum limit for the intended application. Cross-reference the physical footprint dimensions against the target PCB layout to guarantee mechanical compatibility before finalizing procurement orders.

Selection Notes

Select this component when a non-invasive current sensing solution is required for frequencies between 20kHz and 100kHz. The 200:1 turns ratio makes it suitable for stepping down higher primary currents to measurable secondary levels. Consider the through-hole package type if surface-mount alternatives are not feasible for the specific mechanical constraints of the design.

Part Context

This part belongs to Eaton's line of current sense transformers designed for electronic power conversion systems. It serves as a critical interface for monitoring electrical flow without direct galvanic connection to the primary circuit. The product is categorized under board-mount sensors within the broader electronics division portfolio.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Engineers should consult Eaton technical support for equivalent components with matching electrical parameters and form factors.
