HLSR / HO Series Current Transducers
A new standard of performance
with Advanced ASIC Technology
HLSR Series
HLSR / HO
Series
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.
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.

Hall-Effect current

HLSR
- A cost-effective current transducer that out-performs shunts in every way.
The compact package of the
HLSR
requires only 387 mm
2
; less board area than many
shunt solutions. Large clearance/creepage distances ensure safety, and its high
performance supports accurate measurements across a wide temperature range of
-40°C to +105°C.
The LEM
