AKKN ElectronicsModern power systems demand unprecedented precision in energy monitoring, yet engineers face persistent challenges with thermal drift, space constraints, and measurement accuracy. The LEM HAS50-S/SP50 current sensor redefines these boundaries through innovative closed-loop Hall effect technology.
Precision Engineered for Demanding Applications
- 50A nominal current with ±0.5% accuracy (IEC 61869-10 certified) ensures reliable load monitoring in critical systems
- 200kHz bandwidth captures transient events for predictive maintenance applications
- -40°C to +85°C operational range eliminates thermal compensation needs in harsh environments
- Compact 29mm profile enables direct PCB mounting in space-constrained designs
Case Studies
Smart Factory Motor Control Upgrade
A European automotive plant reduced unplanned downtime by 40% after implementing HAS50-S sensors in their 480V motor drives. Real-time current monitoring detected bearing wear 72 hours before failure (LEM Case Study 2023).
EV Fast-Charging Load Balancing
Network operators achieved 15% faster charge cycles using the SP50 variant's 1μs response time for dynamic power distribution. The solution handled 150kW peak loads while maintaining 0.8% measurement consistency (EMobility Tech White Paper 2022).
With 63% lower power consumption than traditional current transformers, the HAS50-S series demonstrates how advanced magnetic field compensation can transform energy management across industries. Its reinforced insulation (3kV RMS) and <2μs propagation delay make it particularly effective for renewable energy systems requiring both safety and speed.
