LINETRAXX® VME420

  • Undervoltage, overvoltage and frequency monitoring of AC/DC systems 0…300 V
  • Various monitoring functions selectable < U, > U, < f, > f
  • Adjustable start-up delay, response delay and delay on release
  • Password protection for device setting
  • Preset function (automatic setting of basic parameters)

The voltage relays of the VME420 series are designed to monitor the frequency, undervoltage, overvoltage and the voltage between two threshold values (window discriminator function) in AC and DC systems. The voltages are measured as r.m.s. values. The currently measured value is continuously shown on the LC display. The measured value leading to the activation of the alarm relays will be stored. Due to adjustable response times, installationspecific characteristics, such as device-specific start-up procedures, short-time voltage fluctuations, etc. can be considered. Device version VME420 requires an external supply voltage.
