LEM HO 60-NP-0100 Key Advantages

The HO 60-NP-0100 employs open-loop Hall effect technology, delivering ±1.4% accuracy and ±0.5% linearity while providing galvanic isolation between primary and secondary circuits . The multi-range capability through primary layout configuration allows a single transducer to cover 15 A, 30 A, or 60 A nominal currents, simplifying inventory management . The ±150 A measuring range provides ample headroom for overload conditions. The 350 kHz bandwidth and 2.5 µs response time capture dynamic current signals with high fidelity .

A key feature is the dedicated overcurrent detection output set at 2.93 × IPN (peak value), enabling fast system-level protection without additional circuitry . The VREF IN/OUT access provides system-level flexibility for reference voltage synchronization . The single +5 V supply simplifies integration into low-voltage digital systems. The compact through-hole PCB design offers low power consumption (25 mA maximum), high immunity to external interference, fixed offset and sensitivity, and no insertion losses . The device is factory calibrated and meets RoHS compliance .
