Voltage monitoring device

For safe voltage monitoring, eibabo offers a wide range of voltage monitoring devices, voltage monitoring relays and voltage measuring relays, mains voltage monitoring devices, and power supply monitoring relays and grid disconnection relays. Devices to monitor the voltage are usually used for monitoring undervoltage. Many devices are suitable for undervoltage monitoring in three-phase systems (each phase against the neutral wire) with a fixed threshold value. Sometimes the voltage monitoring devices are equipped with a fixed hysteresis as well as an integrated test button. When you press the test button on the device, the output relay drops. The devices can also be used for monitoring a single phase: Connect all unused inputs with a connected phase, because the missing voltage would otherwise be displayed. The output relay of the voltage monitoring device switches on when the measured voltage of all connected phases exceeds the fixed value (including hysteresis). The output relay switches off again when the voltage of one of the connected phases falls below the fixed value. Please remember that no error message occurs in devices for sole undervoltage monitoring if there is reverse voltage from a consumer that is higher than the set threshold value. Mains decoupling relays monitor voltage and frequency in three-phase systems and can, in connection with inverters with integrated isolated network detection, be used for monitoring the NA-protection. Many voltage monitoring devices monitor the presence of the neutral conductor, the current under-voltage and over-voltage. The respective threshold usually has its own adjustable delay. If a voltage fault occurs, the corresponding relay (undervoltage output and overvoltage output) opens after the delay set by you. If the neutral conductor fails, the two relays normally open immediately without delay. We provide high-quality devices for voltage monitoring from all major manufacturers such as Schalk, Finder, Metz Connect, Ziehl, Dold & Söhne and Siemens, Bender, Hager or by Schneider Electric or Tele Haase.
