Overview
The CSE187L-B is a low-frequency current sense transformer manufactured by Triad Magnetics. It features a 500:1 turns ratio, designed for PCB mounting applications. The primary current rating is 30A, while the secondary output provides 0.060A. The operational frequency range spans from 50Hz to 400Hz. The component has a maximum seated height of 18.03mm.
Feature Summary
- Provides precise current sensing via a fixed 500:1 transformation ratio
- Engineered for direct printed circuit board (PCB) mounting
- Operates effectively across a wide frequency spectrum from 50Hz to 400Hz
Applications
- Industrial power monitoring systems
- Electrical protection circuits requiring accurate current feedback
- Power supply control loops
Procurement Notes
Verify the specific suffix against official Triad Magnetics documentation to ensure correct pinout and electrical characteristics. Confirm that the 30A primary rating aligns with your system's peak load requirements. Check for RoHS compliance status in the latest datasheet revision before finalizing procurement orders.
Selection Notes
Select this component when a high-ratio current transformer is needed for low-voltage AC signals. Ensure the PCB layout accommodates the specified physical dimensions and mounting style. Validate that the 50-400Hz frequency range matches the source signal to avoid phase shift or attenuation issues in the sensing circuit.
Part Context
This part belongs to the Current Sense Transformers family from Triad Magnetics. It serves as a specialized passive component for measuring alternating current in electronic circuits. The design focuses on providing isolated current data for control and monitoring purposes without introducing significant burden voltage into the primary circuit.
Replacement Considerations
Consult official manufacturer substitution lists for verified alternatives. Generic equivalents may not match the specific 500:1 ratio or 30A primary rating. Verify mechanical footprint compatibility if considering cross-brand replacements.
