Revolutionize Energy Management: LEM HAS100-S/SP50 Sensing Breakthrough

The Current Sensing Challenge

Modern power systems demand millimeter-perfect current measurement while battling electromagnetic interference (EMI), temperature swings, and space constraints. Traditional Hall-effect sensors struggle with ±2% accuracy drift above 85°C (per IEEE Transactions on Industrial Electronics), causing costly calibration cycles.

Precision Redefined

The LEM HAS100-S/SP50 closed-loop current sensor delivers surgical-grade measurement through three engineering advancements:

100A nominal current with ±0.5% accuracy (25°C) ensures compliant operation in ISO 13849-1 safety systems
-40°C to +125°C operating range with <0.1%/K drift eliminates thermal recalibration (LEM Lab Report #HAS-2123)
4kV galvanic isolation withstands voltage spikes in 480VAC motor drives (UL 61800-5-1 certified)
