HC-ASA Medium current range / Bolt on type

RoHS compliant







  • Rated current: 200A–900A
  • Small size handles large current (MAX 900A)
  • Ensures broad operating temperature range
    (-40°C ~ +125°C)
  • 5V single power supply ratio metric specifica-
  • Attached to chassis, cable output specifications


xEV inverters (HEV, EV, PHEV, etc)

Note1)The indicated residual voltage is the one after the core hysteresis is removed.

Note2)Output specifications include 100-Ω output resistance and 1-mA maximum output current.

Note3)Since residual output is ratiometric output, it varies according to the control power supply value.

Note4)Code at the end of the model name represents harness specifications.
