FRS1000-SBI Industrial High-Precision Current Transducer — The Core Sensing Solution for Intelligent Power Monitoring
The FRS1000-SBI is an open-loop Hall effect current transducer developed by LEM of Switzerland, specifically engineered for industrial-grade high-precision current monitoring. It non-contactly and linearly converts primary currents up to 1000 A (AC + DC) into a standardized 4–20 mA analog current output, enabling isolated, stable transmission and seamless integration of current data into control systems. Designed for applications demanding stringent requirements in safety, accuracy, and electromagnetic immunity, it is ideal for industrial automation and energy management systems.
High Accuracy: Measurement precision of ±0.65%, significantly outperforming conventional current transformers to ensure data reliability.
Wide Frequency Response: Simultaneously measures AC + DC currents without magnetic saturation, ideal for complex waveforms including pulses, harmonics, and ripple.
Interference-Resistant Output: 4–20 mA current loop output provides inherent immunity to electromagnetic interference, suitable for long-distance transmission (>1 km) in industrial environments.
Wide Supply Voltage: Operates on a single 12–24 V DC external supply, fully compatible with mainstream industrial power systems and enabling flexible deployment.
Extended Temperature Range: Functions reliably from -40°C to +85°C, making it suitable for cold, hot, outdoor, and enclosed electrical cabinet environments.
Compact Design: Modular form factor minimizes installation space and facilitates integration into switchgear, inverters, and PLC systems.
