Overview
The CSE187L-P is a current sense transformer manufactured by Triad Magnetics, designed for PCB mounting applications. It features a 500:1 turns ratio with a 30A primary current rating and a 0.060A secondary output. The device operates within a frequency range of 50 Hz to 400 Hz. Physical dimensions include a width of 21.5 mm and a maximum seated height of 18.03 mm.
Feature Summary
- Provides precise current sensing capabilities through a defined 500:1 transformation ratio.
- Supports high primary current handling up to 30 amperes for robust industrial monitoring.
- Engineered for direct printed circuit board integration using surface mount technology.
Applications
- Industrial motor drive current monitoring
- Power supply overcurrent protection circuits
- AC/DC converter feedback loop sensing
Procurement Notes
Verify the specific suffix designation against official Triad Magnetics documentation to confirm exact pinout configuration and mechanical tolerances. Ensure that the selected variant aligns with the required PCB footprint and thermal management specifications for the target application environment.
Selection Notes
Select this component when a compact solution is required for monitoring AC currents in the 50-400 Hz range. The 500:1 ratio suits applications needing accurate signal scaling from high primary currents down to manageable secondary levels for downstream processing or protection logic.
Part Context
This part belongs to the CSE series of current sense transformers from Triad Magnetics. These components are specialized for low-frequency operation and are distinct from general-purpose power transformers, focusing instead on accurate signal representation for control and protection systems.
Replacement Considerations
Consult official manufacturer cross-reference lists for verified substitutes. Generic equivalents may not match the specific 500:1 ratio or 30A primary rating required for safe operation in sensitive control circuits.
FAQ
