AS-210

Current Sense Transformers Overview

The AS-210 is a current sense transformer manufactured by Amgis, LLC. It is designed for applications requiring accurate current monitoring and isolation. The component utilizes toroidal magnetic core technology to provide high-frequency performance and low insertion loss. Key electrical characteristics include a specific current ratio and secondary inductance values tested at defined frequencies and voltages. The device supports primary-to-secondary turns ratios ranging from 1:50 up to 1:500, with testing protocols varying based on the ratio. It features low DC resistance and high insulation capabilities suitable for power supply feedback loops.

Current Sense Transformers Feature Summary

• Provides galvanic isolation between primary and secondary circuits
• Utilizes toroidal core design for efficient magnetic coupling
• Supports variable turns ratios for diverse current sensing needs
• Engineered for high-frequency operation with minimal signal distortion

Current Sense Transformers Applications

• Switching power supply current mode control
• Overcurrent protection circuits
• Active clamp flyback converters
• Resonant converter topologies

Current Sense Transformers Procurement Notes

Verify the specific turns ratio required for your application against the manufacturer's standard offerings. Confirm that the secondary inductance meets the controller's input impedance requirements. Ensure the package dimensions align with your PCB layout constraints. Request detailed datasheets for precise electrical parameters before finalizing the order.

Current Sense Transformers Selection Notes

Choose the AS-210 when isolated current sensing is critical for system safety and control loop stability. Consider the maximum primary current rating to avoid saturation. Evaluate the frequency range of your switching regulator to ensure compatibility with the transformer's bandwidth. Check the physical size limitations if space is constrained within the power stage.

Current Sense Transformers Part Context

Amgis, LLC specializes in toroidal power transformers and high-frequency magnetic components. The AS-210 belongs to their line of current sense transformers, which are distinct from general-purpose power transformers. These components are engineered for precision measurement rather than power transfer, focusing on linearity and phase accuracy.

Current Sense Transformers Replacement Considerations

Direct substitutes must match the primary-to-secondary turns ratio and physical footprint. Verify that alternative current sense transformers offer comparable secondary inductance and DC resistance. Ensure the replacement part maintains the same isolation voltage rating and operating temperature range as the original AS-210 specification.
