Main specification

HBA-T20 (for controls by a single phase power controller)

  • Input type: Load voltage and current transformer (CV-1-[])
  • Detectable load current: 5A, 30A, 100A ac (depends on CV-1 rating)
  • Settable range: 50 to 100% of CV-1 rated value
  • Accuracy of load setting: ±3% of load set value
  • Alarm sensitivity: Current change by 10% or more of load capacity.
    ※Uncertain for the change of less than 10%

HBA-T30 (for controls by a three phase power controller)

  • Input type: Load voltage and current transformer (CV-1-[])
  • Detectable load current: 5A, 30A, 100A ac (depends on CV-1 rating)
  • Settable range: 50 to 100% of CV-1 rated value
  • Accuracy of load setting: ±3% of load set value
  • Alarm sensitivity: Current change of 15% or more of load capacity.
    ※Uncertain for the change of less than 15%

<Common specification>
