Product Description
High-Accuracy Compact Current Sense Transformer for PCB Power Monitoring
The ACST0908 Series is a high-performance family of Current Sense Transformers engineered for precise AC current monitoring in modern power electronics. Designed for PCB-mount applications, these compact transformers offer stable turns ratios, low DCR, and strong isolation performance, making them ideal for switched-mode power supplies, motor control circuits, lighting systems, and industrial automation equipment.
With primary current ratings of 15A, and secondary inductance up to 60 mH, the ACST0908 Series provides reliable operation across a broad frequency range from 50 kHz to 500 kHz. Each model features optimized construction to ensure consistent output accuracy and excellent thermal stability under varying load conditions.
As part of advanced AC Current Sensors used in power monitoring and feedback loops, the ACST0908 Series helps engineers achieve enhanced efficiency, safety, and control in mission-critical AC systems.
