Phase Sequence Monitor / Phase Failure:

  • Installing the Electro 11 pin plug-in series of control and timing devices is simple and straightforward since they are designed to fit into a conventional 11 pin base.
  • Phase failure, phase reversal, and phase imbalance are detected by the SF1 by monitoring the negative phase sequence (NPS) voltage.
  • The unit's NPS voltage is set at 7%.
  • The unit will de-energize if any of these malfunctions take place.
  • Re-energizing the relay is contingent upon the supply voltage self-correcting.
  • If there is a balanced voltage variation, the unit won't respond.

Features:

  • 10A SPDT Relay ON LED Output.
  • Finding phase asymmetry.
  • Unable to react to regenerated EMF.
  • Quick reaction to reversing phase sequence.
  • Relay monitoring for three-phase voltage regulation.
  • Checks to see if all three stages are present and happening in the right order.
  • Unaffected by balanced supply voltage fluctuations.
