    LEM AKR 5 C420L True RMS Solid-Core AC Current Transducer


    LEM AKR 5 C420L Product Overview

    The AKR 5 C420L is a solid-core AC current transducer from LEM's AKR True RMS series, designed for the electronic measurement of AC currents with complex, non-sinusoidal waveforms (including distorted VFD and SCR outputs) and galvanic isolation between primary and secondary circuits . The C420L variant features jumper selectable measuring ranges (2A, 5A) and a loop-powered True RMS 4-20mA current output .

    Rated for 5 A nominal with selectable 2A/5A measuring ranges, it outputs 4-20mA with ±1% accuracy . Bandwidth is 10Hz to 400Hz and delay time to 90% of final output is <600ms . Supply voltage is 24V DC (loop-powered) . Mass is 90g and operating temperature is -20°C to +50°C . Insulation test voltage is 3kV with 150V AC rated voltage (CAT III, PD2) .

    LEM AKR 5 C420L Key Advantages

    The AKR 5 C420L employs True RMS responding technology, delivering accurate measurement on distorted VFD and SCR waveforms where conventional average-responding sensors fail . True RMS integrates the actual waveform over time, providing reliable readings even with numerous spikes and dips per cycle. The loop-powered 4-20mA output simplifies wiring and reduces installation costs for industrial control systems . Jumper-selectable ranges (2A/5A) provide flexibility without hardware changes. The solid-core design delivers precision measurement with no insertion losses, and 3kV isolation ensures safety in industrial environments . The device complies with IEC 61010-1 safety and EN 61326 EMC standards .

     

    LEM AKR 5 C420L Typical Applications

    VFD Controlled Loads (motor and load monitoring from VFD output)
    SCR Controlled Loads (phase angle fired or burst fired SCR systems)
    Switching Power Supplies and Electronic Ballasts
    Automation systems and data loggers
    Panel meters and power management

     

    Why Choose the LEM AKR 5 C420L?

    The AKR 5 C420L combines True RMS accuracy, jumper-selectable ranges 2A/5A, loop-powered 4-20mA output, and solid-core design in a compact panel-mount package weighing 90g. Manufactured by LEM, it delivers stable, accurate, and safe AC current measurement for VFD, SCR, and other non-linear loads. The C420L variant is distinguished by its True RMS capability and jumper-selectable ranges, designed for applications where waveform distortion is present . The part is Active, RoHS compliant, and available through authorized distributors.
