How to Accurately Measure Current with LEM CTSR0.3-P for Energy-Efficient Designs

When it comes to current measurement in power electronics, precision and reliability are key. The LEM CTSR0.3-P is a standout option for engineers aiming for energy-efficient designs. This compact current transducer offers a nominal primary current of 0.3 A and an insulation voltage up to 1000 Vrms, making it ideal for applications such as solar inverters, motor controls, and battery management systems.\u00a0LEM, known globally for its innovative solutions in current sensing, has engineered the CTSR0.3-P with an accuracy class of 0.6%, ensuring minimal errors even under varying load conditions. For instance, in a recent case study involving a 5 kW solar inverter, the CTSR0.3-P demonstrated consistent performance with less than 0.4% deviation across the entire operating temperature range (-40°C to +125°C). This level of stability is crucial for maintaining system efficiency and longevity.\
