LEM has three families of split-core current sensors that can be clamped around a busbar or cable without moving the conductor.
Speedy installation for current transducers
LEM has new families of current transducers with an innovative design that dramatically reduces installation time.
Additional features of the AP and APR series are the user-selectable measuring ranges (from 10A to 400A), choice of output options available (4-20mA or 0-5/0-10V), and a large sensing aperture with built-in strain relief for the primary conductor.
In an industry first, the AP and APR products rely on a patented sensing technique known as PRIME technology (planar Rogowski I measurement), where current is sensed without the use of a traditional magnetic circuit.
This unique, technological innovation gives the transducer immunity against saturation due to overcurrent conditions while maintaining an absolute accuracy of better than 0.8% over a broad range of inputs.
This, coupled with a wide, 1kHz bandwidth, an operating range of -20 to +60C, and the availability of a true RMS model (APR) for nonlinear loads or "noisy" environments, make the AP and APR transducers an excellent choice for system designers, system integrators and automation distributors looking for accurate and cost-effective DIN-rail mounted AC current transducers.
