About company

The "MEANDR" electrotechnical company founded in 1992 in St.-Petersburg, specializes in development and production of industrial automation tools.

During more than 20 years of its activities, our company became the recognized leader in production of different domestic electronic relays. Our nomenclature has more than 500 products.
Among our partners there are many large enterprises of various industries, such as: Electrosila, Severstal, Sevzapmontazhavtomatika, Areva, Kaliningradgazavtomatika, Tauras Feniks, Russkaya Trapeza, Zvezda-Energetika, Aurora, Lenenergo, Novaya Era, RAP Holding, Samarskiy Transformator, Severnaya Zaria and many other Russian companies.
Below there is a short list of our products:
  • Electronic time relays

On the basis of our devices, we produce systems for different purposes:
  • edge position control systems for a coiled material
  • speed monitoring systems
  • production calculation systems (flow meters)
On a demand basis, we will produce following products:
  • Relay RKSN-1 to control an escalator stairs’ speed and a motion direction, to account its total operating time, to calculate a braking way and number of switchings
  • Controller KUPT-2 to control a tunnel kiln when manufacturing squeeze bottles
  • Controller UKM-1 to control a molding machine when manufacturing squeeze bottles
