    LEM AK 50 B10 AK-B Series Split Core Current Transducer

    LEM AK 50 B10 Product Overview

    The AK 50 B10 is a split-core current transducer from LEM's AK-B Series, designed for the electronic measurement of AC sinusoidal waveforms with galvanic isolation between the primary (high power) and secondary (electronic) circuits. The transducer features jumper-selectable ranges and is self-powered, requiring no external supply voltage.

    Rated for 10 A, 20 A, or 50 A nominal via jumper selection, it outputs a 10 Vdc analog voltage signal with ±1% accuracy. Response time is less than 100 ms and bandwidth is 50-60 Hz. Operating temperature ranges from -20°C to +50°C with 0-95% RH. Mass is 120 g and insulation test voltage is 3 kV AC. The large aperture design simplifies installation without interrupting the primary circuit.

    LEM AK 50 B10 Key Advantages

    The AK 50 B10 employs average responding measurement technology, delivering ±1% accuracy for AC sinusoidal waveforms while providing galvanic isolation between primary and secondary circuits for enhanced safety. The jumper-selectable 10 A, 20 A, and 50 A ranges offer flexibility for various applications without requiring multiple transducers. The self-powered design eliminates the need for a separate supply voltage, simplifying installation and reducing system complexity. The split-core construction with large aperture enables easy mounting without disconnecting existing cables, minimizing system downtime. The 3 kV AC insulation ensures safe operation in industrial environments.

     

    LEM AK 50 B10 Typical Applications

    Automation and process control systems
    Panel meters for power consumption monitoring
    Data loggers for remote current recording
    Motor current monitoring and protection
    Building automation and energy management
    Imaging and vision system power monitoring
    Industrial control cabinets
    HVAC equipment monitoring

     

    Why Choose the LEM AK 50 B10?

    The AK 50 B10 combines jumper-selectable 10 A, 20 A, and 50 A current ranges with 10 Vdc analog output in a compact, split-core package. Manufactured by LEM, it delivers stable, accurate, and safe AC current measurement for industrial and automation applications. The self-powered design offers simplified installation and maintenance, while the large aperture and panel mount configuration provide flexible integration options.
