LRM4IO expansion module

We would like to present the accessories, which complement our existing range of products and expand it with new, additional functionalities. At Lopi, we constantly strive to ensure that our reactive power compensation systems work as efficiently as possible. At the same time, we want them to be intuitive to use and economical in operation as well as to extend the service life of all the components of the power system. Therefore, we are expanding our solutions for reactive power compensation with new devices.

LRM4IO expansion module

 

  • development of inductive and capacitive reactive power compensation systems by increasing their capabilities and functionality
  • data transmission systems of selected areas
  • management through the power guard
  • registration of changes at signalling inputs with the readout option
