 0 RELAY

This device is used to measure and display true RMS AC voltage signals.

 FEATURES INCLUDE:

  • DISPLAY SCALE: adjust the display to match the input of a voltage transformer
  • START-UP DELAY: At START-UP delay relay remains energized for this pre-set time to allow input voltage to stabalize before monitoring starts.
  • REACTION DELAY: (TRIPP DELAY) Once energized, the relay will tolorate fault conditions for this pre-set time before it is de-energized. This allows for short term fault conditions.
  • RECOVERY DELAY: Whenever the relay is de-activated, it will not operate again until this time has lapsed
  • LATCH FACILITY: Once de-energised, the relay will not operate until the short across the latch pins is removed (even if the fault condition has been corrected)
  • Auxilliary supply voltage is isolated from the measured AC
  • keypad lock with code

ADJUSTABLE PARAMETERS:

SCALE: 5V - 3050V
