The LTC500-SF/SP6 is a high-performance current transducer specifically designed for modular railway traction systems. With a rated measurement current of 500 A, it is ideal for critical current monitoring in railway traction, industrial drives, renewable energy generation, and many other demanding fields.
High Accuracy & Linearity: ±0.1% linearity and ±0.6% accuracy ensure true, reliable current measurement for precision control applications such as EV chargers, photovoltaic inverters, and servo drives.
Ultra-Fast Dynamic Response: 1 μs response time dramatically improves dynamic performance in motor control, variable frequency drives, and other applications requiring fast current feedback, effectively reducing overcurrent risks.
Wide Temperature & Strong Immunity: Stable operation from -40°C (severe outdoor cold) to +85°C (high-temperature enclosed cabinets). Built-in shielding effectively suppresses electromagnetic interference, ensuring signal purity.
High-Safety Isolation: 12 kV isolation voltage effectively blocks potential interference and fault conduction from the primary high-current circuit, protecting downstream control systems and operator safety.
High Reliability: Compliant with the EN 50155 railway standard, UL94-V0 flame rating, and CE EMC directive; also meets NFF 16101/2 fire and smoke requirements. Provides long-term stable operation in harsh industrial environments.
