SF1_K Sequence Monitor with Adjustment

R422.02

The SF1 Monitors negative phase sequence (NPS) voltage to detect phase failure, phase reversal and phase imbalance. The NPS voltage of the unit can be djusted from 7-15%. When any of these faults occur the unit will de-energize. The relay will only re-energize if the supply voltage corrects itself. The unit will not react to a balanced voltage variation

 

Features:

 

  • Monitoring relay for 3-phase voltage control
  • Measures if all 3 phases present and in sequence
  • Detection of phase asymmetry
  • Insusceptible to balanced supply voltage variation
  • Insensitiveto regenerated EMF
  • Fastresponse to reverse phase sequence
  • Relay ON LED
  • Output 10A SPDT
