Key Advantages: Why Choose the LTC500-S/SP6?

1. Genuine LEM – Swiss Quality Assured

LEM is a global leader in electrical measurement sensors, widely used in rail transportation, industrial automation, new energy vehicles, energy management, and other high-end applications. Choosing LEM means choosing stability and reliability. 100% original, no counterfeit risks – complete peace of mind.

2. Closed-Loop Hall Effect Technology – Proven Accuracy

The closed-loop Hall effect technology delivers higher linearity, lower temperature drift, and faster dynamic response than open-loop solutions. Whether measuring steady DC or high-frequency AC, the sensor provides high-fidelity output, giving your control algorithms a solid data foundation.

Accuracy: ±0.6% (within rated current range)

Bandwidth: 0~100 kHz

Dynamic performance: di/dt tracking ≥ 50 A/μs – ideal for capturing pulsed currents.

3. Wide Overload Margin – Handles Transient Overcurrents with Ease

With a rated current of 500 A and an ultra-wide measuring range up to ±1200 A, the sensor reliably delivers even during system start-up or load surges. It withstands overloads up to 20 times the rated value without damage – LEM’s engineering margin makes your system more robust.

4. Modular, Flexible Mounting – Easy System Integration

The LTC500-S/SP6 features a compact modular design with integrated mounting feet for panel installation. The primary side has a 27.5 mm through-hole for busbars or cables, while the secondary side uses a Molex MiniFit.Jr pluggable connector for fast and reliable wiring, greatly simplifying field work. Efficient installation and maintenance in tight spaces – invaluable flexibility for system integrators.

5. Wide Temperature Range – Designed for Harsh Environments

The sensor operates reliably across -40℃ to +85℃. Whether in bitter cold outdoors or high-temperature sealed enclosures, the LTC500-S/SP6 ensures stable, accurate current measurement.

6. High Isolation Voltage – System Safety Assured

Galvanic isolation between primary and secondary circuits provides an isolation test voltage of 12 kVRMS (50 Hz, 1 min), effectively protecting low-voltage control circuits from potential hazards on the high-voltage main circuit. Stray capacitance between primary and secondary is negligible for almost all applications.

LTC500-S/SP6 Typical Applications

Thanks to its wide measuring range, high accuracy, and wide operating temperature, the LTC500-S/SP6 is widely used in:

Industrial drives & servo systems – real-time current monitoring for vector control and overcurrent protection in single or three-phase inverters.

Traction systems & rail transportation – current detection in traction and auxiliary converters, meeting the stringent reliability demands of railway systems.

New energy equipment – output monitoring in PV inverters and wind power converters.

Charging infrastructure – DC/AC current measurement in EV charging stations.

Switch-mode power supplies & UPS – current closed-loop control in power conversion stages.

The LTC series has become a hidden critical component in high-end industrial control systems. Its proven performance – 0.6% accuracy, -40℃~85℃ temperature range – makes it a popular choice in the trend towards high-quality components.
