In everyday industrial current measurement, users often face pain points like inaccurate readings, excessive drift (data still wandering half an hour after startup), slow response that misses transient overshoots, or frequent false triggering due to noise/interference, even sensor burnout from overload.
The LF210-S/SP3 is designed to perfectly solve these “tough problems”.
Fluxgate-level accuracy at Hall-effect price:
This product achieves ±0.2% overall accuracy – a rare high standard in the industry – combined with extremely low thermal drift (offset drift only 0.1% of Ipn). No more worries about measurement errors caused by temperature changes. Its performance directly rivals expensive fluxgate technology but at the cost of a Hall-effect sensor – a true “game changer” for high-precision applications.
Ultra-fast response, nanosecond capture:
With response time typically below 0.5 µs and bandwidth DC ~ 100 kHz, even high-order harmonics, sudden load changes in extreme conditions, or millisecond fault spikes cannot escape its “eagle eye”. Even in harsh environments, its closed-loop Hall technology ensures stable, true signal output for DC, AC, and pulsed current measurements (bidirectional and isolated up to 200 A).
High isolation & extreme environmental resilience:
The LF210-S/SP3 holds multiple rigorous safety certifications including UL 508. It offers an insulation test voltage of 3.5 kV and impulse withstand voltage of 8.8 kV, ensuring downstream circuitry safety in high-voltage environments. It also supports a -40°C to +85°C wide operating temperature range, with all components tested for life at 105°C and strong EMI immunity – truly rugged and durable.
