Iskra Systemi MVR 54 Series Voltage Monitoring Relay

MVR 54 Series serves to monitor voltage, phase failure and sequence in     switchboards, protection of devices in 3-phase mains

Features

 

  • Upper and lower level of monitoring voltage
  • Adjustable time delay eliminates short voltage peaks and failures in     the main
  • Supply is done from monitored voltage
  • Faulty state is indicated by red LED and by opening of output relay     contact
  • Output contact  1 x Changeover / SPDT 8 A /250 V AC1
  • In case supply voltage falls below  60 %Un (U lower level) relay off     immediately opens without delay
  • MVR 54 - supply from all phases which means that relay is functional also in case when one phase is faulty
  • Variant MVR 54N - supply  L1-N, means that relay monitors also failure of neutral wire
  • 1-MODULE, DIN rail mounting

Relay in 3-phase main monitors size of phase voltage.  It is possible to set two independent voltage levels and thus it is possible to set two independent voltage levels and monitor e.g. undervoltage and overvoltage independently. In normal state when voltage is within set levels, output relay is closed and red LED shines.

In case  voltage exceeds or falls below the set levels, output relay opens and red LED shines ( LED indicates faulty state – flashes when timing). In case supply voltage falls below 60 % Un (UOFF lower level)relay immediately opens without delay and faulty state is indicated by red LED.In case timing is in progress and faulty state is indicated, timing is immediately stopped.
