Current Sense Transformers datasheet and documents for AS-104
Current Sense Transformers Overview
The AS-104 is a current sense transformer manufactured by Amgis, LLC. It features a vertical rectangular (VRT) form factor designed for high-current applications up to 15A. The component utilizes a 1:500 turns ratio to provide accurate signal isolation and scaling. Key electrical characteristics include secondary inductance testing at 10kHz with 10mV excitation for ratios between 1:50 and 1:500. The physical dimensions include a maximum seated height of 0.803 inches (20.40mm).
Current Sense Transformers Feature Summary
- Provides galvanic isolation for current sensing circuits via electromagnetic induction.
- Supports high primary current handling capabilities up to 15A.
- Offers precise signal transformation through a fixed 1:500 turns ratio.
Current Sense Transformers Applications
- High-current power supply monitoring systems
- Industrial motor drive current feedback loops
- Inverter and converter protection circuits
Current Sense Transformers Procurement Notes
Verify the specific package orientation and pin configuration against the mechanical drawings provided in the official datasheet. Confirm that the operating frequency range aligns with the 10kHz test conditions specified for the secondary inductance parameters. Ensure the primary current rating of 15A meets the system's peak load requirements without saturation.
Current Sense Transformers Selection Notes
Select this component when a robust, high-current isolated sensing solution is required. The 1:500 ratio is suitable for stepping down significant primary currents to manageable levels for downstream ADC or comparator inputs. Consider the vertical rectangular footprint for PCB layout constraints where space efficiency is critical.
Current Sense Transformers Part Context
The AS-104 belongs to the Amgis LLC family of current sense transformers. These components are engineered for reliability in magnetic applications. The manufacturer specializes in toroidal power transformers and inductors, ensuring consistent quality in magnetic core materials and winding techniques for industrial-grade performance.
Current Sense Transformers Replacement Considerations
Direct substitutes require matching the 1:500 turns ratio, 15A current rating, and vertical rectangular package dimensions. Verify secondary inductance specifications at 10kHz to ensure equivalent signal fidelity. Cross-reference mechanical mounting holes and terminal configurations for board compatibility.
