If you’re working on industrial automation or renewable energy projects, accurately measuring current is crucial. This is where the LEM HAS500-S and SP50 come into play. These current sensors are renowned for their precision and reliability in harsh environments. The HAS500-S series from LEM offers a measurement range of up to 500A, making it ideal for high-power applications such as inverters, motor drives, and uninterruptible power supplies (UPS). According to LEM‘s technical documentation, these sensors can achieve an accuracy of ±0.6% at full scale, which is impressive for demanding industrial setups.”One practical example involves using the HAS500-S in solar inverter systems. As renewable energy adoption grows, ensuring efficient energy conversion is essential. With its galvanic isolation feature, the HAS500-S provides safe and accurate current monitoring even under fluctuating conditions. Similarly, the SP50 sensor complements smaller-scale applications like battery management systems or electric vehicle charging stations. Its compact size and ±1% accuracy make it perfect for space-constrained designs.”Both models use Hall effect technology, which eliminates the need for direct contact with live conductors, enhancing safety and reducing heat dissipation. For instance, in an automotive application, the SP50 could monitor the current flowing through an electric vehicle’s traction system without interfering with the circuit. Additionally, these sensors support both AC and DC measurements, offering versatility that many competing products lack.\
