In the fast-growing world of industrial automation and renewable energy, accurate current measurement is the key to stable operation and high system efficiency. The LEM HAS100-S Hall-effect current sensor, with its high precision, excellent galvanic isolation, and compact rugged design, is the preferred choice of engineers worldwide for variable frequency drives, power supplies, and new energy applications.
The HAS100-S uses an advanced open-loop Hall-effect principle, providing 3.6 kVrms (peak 5000V) galvanic isolation between the primary (high voltage) and secondary (low voltage) sides. In high-voltage DC systems and complex industrial environments, it effectively protects your control circuits and eliminates safety hazards.
Rated primary current 100A, measuring range up to ±300A – DC, AC, or pulsed currents are captured accurately. With ±1% accuracy and ±1% linearity, your control system always receives reliable real-world data.
DC~50kHz frequency bandwidth and a 3µs fast response time enable real-time tracking of rapid current changes. For high-dynamic motor drives and inverters, this means more precise control and higher efficiency.
–10°C to +80°C wide operating temperature, combined with a UL 94-V0 flame-rated housing, ensures stable performance in harsh environments, from freezing cold to extreme heat.
Through-hole/panel mounting, compatible with standard Molex connectors – quick installation, no calibration required. ±15V dual supply, ±4V analog voltage output, easy integration into any control system.
