World-leading electrical connectivity and electronics supplier, Weidmuller has launched the new Varitector Logger 30 designed to register and document large current pulses as well as the frequency and time of the incidents.

The new plug and play Varitector Logger 30 surge loggers count the current pulses greater than a set threshold value, which are discharged by PE conductors on surge protection devices. Any lightning strikes and surge voltages are continuously recorded and each measurement issued with a time stamp accurate to the hour. Both the time and date of the incident’s occurrence are recorded.

Using this information, engineers can design and implement appropriate systems as well as tweak existing ones to ensure they are continuously functioning at optimal levels and protected against surges. Maintenance staff can verify installed units and forward plan routine maintenance tasks.

For accurate measurement of currents, the Varitector Logger 30 surge logger features an external sensor with a ferrite toroid. Clipped to the earth cable, it detects current peaks on the PE conductor, which can be caused by events such as a lightning strike.

An ideal complement to Type-II and Type-III VPU surge protection devices, the Varitector Logger 30 can be quickly and simply installed on the terminal rails in almost every switch cabinet via its plug and play housing.

Key features of Varitector Logger 30 surge loggers:

  • Date and time documentation allows the user to historically document incidents to help determine the cause of the surge
  • Generously large device memory ensures comprehensive documentation of data
  • Large and clear, two-line LCD display provides easy visualisation of current/incident data
  • Buttons on the device allow the menus to be navigated effortlessly
  • Standard internal CR123A replaceable 3-V battery with at least 4-year service life
  • Operating temperature range between -20°C and +60°C
  • V-0 flammability rating in accordance with UL94
  • Meets EN62561-6 and VDE 0185-561-6 standards
