Compact current transducers run up to
1000A
A new family of current transducers combines Hall effect technology and a signal conditioner in a compact case to offer dramatic savings in size for measuring nominal currents up to 1000A true RMS.
LEM has introduced a family of current transducers that combines Hall effect technology and a signal conditioner in a compact case to offer dramatic savings in size (up to 75% compared with other current transducers) for measuring nominal currents up to 1000A true RMS These new transducers measure only 90 x 70 x 34mm

Current sensors slip on in a trice
LEM has three families of split-core current sensors that can be clamped around a busbar or cable without moving the conductor.
The DHR series has been designed to measure DC signals as well as distorted current waveforms such as variable frequency drive (VFD) outputs.
Additional features include the choice of primary current measuring ranges from 100 to 1000A, choice of output options (4-20mA, 0-5V or 0-10V), a wide power supply range (24 to 50V DC) and a large sensing aperture (32mm) for noncontact measurement.
The new transducers provide an absolute accuracy of better than 1% of the nominal current over a broad range of inputs.
This, coupled with a wide bandwidth from DC to 6kHz, an operating range of -40 to +70C and a true RMS computation for nonlinear loads or "noisy" environments, makes them an excellent choice for industrial system designers, system integrators and automation distributors looking for accurate and cost-effective AC or DC current transducers.
