Current Transducers with Advanced ASIC technology
Special effort has been focused on a new Application Specific Integrated Circuit (ASIC)
to meet industry trends in power electronics for optimisation of costs & reduction of size,
together with performance improvement, resulting in a new generation of ASIC specific
current transducers based on the Open Loop Hall effect technology leading to the
development of the HLSR & HO series.
New ASIC die, a
complete Open Loop
Hall effect current
transducer on a single
chip.
Open-Loop,
Hall-Effect current
transducers using
an ASIC in the
gap of the core.
With various versions of this ASIC at its heart:
• the HO models have been designed for current measurements from 2.67 A
to 25 A
nominal, with nine possible current ranges selectable either by digital
programmability or by multi-range PCB configuration.
• the HLSR models have been designed for current measurements from 10 A to 50 A
nominal, with five possible current ranges.
