STW-DI01C-2001H Fluxgate Current Sensor （Analog output）
✨Features
Product Introduction
This High-Precision Closed Loop Current Sensor is designed for critical applications requiring laboratory-grade measurement accuracy. By employing Magnetic Balance (Hall Effect) technology, it delivers a linearity and accuracy rating of 0.05%, making it vastly superior to standard transformers or open-loop sensors.
The device operates on a dual power supply (±12V or ±15V) and outputs a secondary current signal based on a 1:2000 ratio. For example, when measuring a 200A load, the sensor outputs a precise 100mA signal. This makes it ideal for feedback control in precision power supplies, variable frequency drives (VFDs), medical equipment (MRI/CT), and high-end test instrumentation. The Φ 20 mm through-hole design ensures galvanic isolation between the high-power primary circuit and the electronic measurement circuit, ensuring safety and reliability.
