Voltage relay


DOLD voltage control modules, available from ELTRON, ensure continuous voltage monitoring in single-phase, three-phase, AC and DC systems. They protect devices against the effects of overvoltage, voltage drops and incorrect phase sequence, supporting the stable operation of installations in automation, power engineering, construction and critical infrastructure.

The offer includes, among others:

  • Voltage relays with LCD display (e.g. MK 9064N, MH 9064) – enable easy setting and reading of parameters,
  • Protection against overvoltage and voltage drops (e.g. BA 9054, IL 9079) – for the protection of power and industrial networks,
  • Medical solutions compliant with VDE 0107 (e.g. IP 9109.27/107) – for use in healthcare facilities,
  • Modules for battery and emergency systems (e.g. BA 9054/331) – with short-circuit and sulphurisation protection,
  • Compact surge arresters (IK 9172, IL 9070) – for installation in confined spaces,
  • Phase failure and short voltage interruption detection (BC 9190N) – ensures high sensitivity in applications requiring reliability.

DOLD modules available from ELTRON offer a wide range of measurement voltages (up to 690 V AC), various output configurations (C/O, NO, NC), and compact sizes from 17.5 mm wide – facilitating integration into existing installations.
