Voltage Presence BVPR271

The BVPR271, Voltage Presence Relay provides an economical and compact solution to monitoring of 3-phase voltage up to 800V phase to phase (500V phase/neutral) with tworelay outputs or external LED and relay indicating

Description

The BVPR271, Voltage Presence Relay provides an economical and compact solution to monitoring of 3-phase voltage up to 800V phase to phase (500V phase/neutral) with tworelay outputs or external LED and relay indicating;

  • Loss of three phases

• Loss of one phase.

The 3-phase voltage plus neutral can be directly connected to the BVPR271 as long as the maximum phase-to-phase voltage does not exceed 800V. To use the BVPR271 with higher voltages, a step down transformers (PT) must be used. Neutral must be connected for proper operation. The BVPR271 is signal powered from the incoming ACvoltage.

Function

  • With any phase present the internal step down DC/DC converter will energise AL1 a relay contact or anexternal LED drive.
  • A trip circuit providing LED indication of phase presence monitors each phase.
  • AL2 will de-energise if any one of the three phases fail.
  • If all three phases are present then both AL1 and AL2 are energised
