LEM introduces split core transducers for high currents

LEM introduces split core transducers for high currents LEM has introduced the AHR series of AC and DC current transducers that offer versatile and precise measurement of nominal currents up to 2000A true RMS, extending the existing family that ranges from 100A to 1000A. These split-core transducers combine Hall-effect technology and signal conditioning in a compact case to offer substantial savings in size (more than 50 percent compared to existing current transformers). They measure only 174 x 86 x 54.1 mm. Devices in the AHR series have been designed to measure DC signals as well as distorted current waveforms such as variable frequency drive (VFD) outputs. They offer a choice of primary current measurement ranges from 500A to 2000A, a choice of standard output types (4-20mA, 0-5V or 0-10V), a wide power supply range (20 to 50 VDC) and large sensing apertures for non-contact measurement (104 x 40 mm busbar, in addition to a 32 mm diameter cable version). The new transducers provide an absolute accuracy better than 1 percent 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 +70degC and true RMS computation for non-linear 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.
