Street lighting powerline controller

Street lighting powerline controller

Control controllers can be part of Unilight lighting control cabinet or work on existing power equipment. Functioning according to the MQTT protocol makes possible to flexibly integrate into various systems.


Key features of the UNILIGHT lighting powerline controller


  • Automatic, manual or remote control of street lighting networks with any light sources;
  • Schedule group management;
  • Collection and transfer of electricity consumption parameters to the Unilight platform;
  • Control of network parameters (voltage, current, power, etc.);
  • Monitoring the status of connected electrical equipment (protective devices, contactors, etc.)
  • Connection channels to the GSM server / Optical fiber / Twisted pair / WiFi;
  • The device is mounted on a standard DIN rail.
