New closed-loop current transducers, based on a custom Hall Effect LEM ASIC, perform at the level of fluxgate transducers, achieving the highest levels of quality and traceability using advanced manufacturing techniques.
Offset drift is over four times lower than the previous generation of closed-loop transducers based on Hall cells and very similar to those using fluxgate.
There are 6 families and 22 models available with various options, such as an integrated reference (VREF), footprint (3 or 4 primary pins with different layouts), with an aperture and/or with integrated primary conductors and overcurrent detection.
• 1.5 to 50 A nominal current
• PCB mounting
• Low offset drift (4 - 14 ppm/°C)
• Overcurrent detection output (LPSR models)
• -40 to +105°C operation
• 100 % compatible with previous LEM generation
• Multi-range configuration
At the heart of power electronics.
