Small & Light Package
Small & light package is realized by coreless &
simple design
Improved External Magnetic Field Tolerance
U-shape bus bar structure improves the
tolerance to external magnetic field by detecting
the magnetic field from the bus bar.
Vout
Ibus
Number of components reduced by coreless design
Minimized the distance between components
Dielectric voltage 2.5kV realized by optimized
layout
.
Vibration resistance improved by light-weight
Smaller PCB area
Improvement in Temperature Drifts
Temperature drifts of offset and sensitivity
are reduced by proprietary circuit design.
Offset (mV)
Low Current Consumption
Low current consumption is realized by design,
less dependency to the amount of primary
electric current.
