Thermosetting plastic

The enclosure is made of SMC plastic with IP 44 or 54. In the II protection class, with a flammability class from HB to V0, in RAL 7035 color, with the possibility of additional varnishing for temporary resistance to environmental effects and UV radiation.

Aluminum OU-1S/OU-2S

Housing made of aluminum sheet (joining by welding or riveting). Powder coated in any color. Dimensions adapted to the type, amount of equipment and individual customer needs. The housing has a high resistance to degradation, environmental impact and UV radiation.

The housing is made in protection class I or II. Protection class II of the housing is achieved by applying an additional insulating layer, permanently lined on the inner and outer surfaces of the housing. The thickness of the layer ensures the proper degree of insulation.

Ventilation allows constant air flow through the use of a ventilation labyrinth, while eliminating the ingress of dirt and the accumulation of water and moisture. Doors having internal hinges with anti-burglary catch and multi-point locking, basquil lock lockable with padlock or system cylinder.

System capabilities

The system makes it possible to reduce the amount of energy consumed through the use of independent types of diffuse and central reduction, while maintaining all the lighting parameters specified by the standards. The solution works with all types of light sources (mercury, sodium, metahalogen, fluorescent, LED). The system provides advanced control and remote supervision of lighting by means of the LIS controller and additional modules that expand its functionality.

Ways to reduce electricity

The proposed control system offers two ways to reduce electricity consumption.

  • Distributed reduction – is carried out through the use of a reducing controller, powered from 1 phase, mounted in a recess in or on a lighting pole, the power range is adapted to the power of the light source. The reducer reduces electricity consumption in leaps of 30 and 60% on the current lighting network with traditional ignition systems and magnetic ballasts. The retrofit does not require any interference with the luminaire. It makes it possible to work with mercury, sodium, metahalide and LED lamps. In the case of LED lamps, by using additional control systems (SC and PLC) and control systems (DV), we can achieve a reduction of more than 60%. Distributed reduction allows independent control of each luminaire, which is impossible with central reduction. With LED luminaires, it is possible to use motion sensors that will respond smoothly to changes in traffic.
  • Central reduction – is carried out by using a single 3-phase autotransformer or transformer reducer, mounted in the SON-R street lighting cabinet. Load power range: 3.5 kVA to 120 kVA, the reducer reduces electricity consumption by 40% (depending on the configuration of the specific lighting network structure), allows to work with mercury, sodium metahalogen, fluorescent lamps. It allows smooth change of output voltage, stabilization of its level and control independently for each phase on the circuit. The reducer allows you to work in individual or cascade mode. The level of reduction and the time of reduction is set remotely. The retrofit does not require any interference with the luminaire and pole. No independent control of each luminaire.

The system and the presented methods of reduction are configured and selected individually to meet the needs of the Recipient.

Controller characteristics

  • Switching on and off according to the sunrise and sunset table (possibility to modify the table and the difference and intervals of switching on individual circuits);
  • Allows smooth adjustment and setting of the level of central reduction (single reducer in the SON-R cabinet) or distributed reduction (reducers in the pole and/or in the luminaire);
  • Allows you to define the difference in switch-on time, night breaks for individual circuits, modify the lighting switch-on and switch-off table;
  • Remote communication, via GSM modem, in GPRS technology (generating alarms and information about network events), has the ability to send and receive SMS;
  • Built-in GPS module responsible for synchronizing time from satellite and allowing the cabinet to be located on maps;
  • Communication with controllers installed in luminaires over 230V network according to LonWorks standard (PLC) and / or radio;
  • Measures voltages, currents, active power consumed and cos fi;
  • Records the measured values for each phase every 1 minute for 30 days;
  • Controls the operation of circuit protection by measuring power (fuse blown detection);
  • The included configuration program and access through the website allow from a computer workstation to fully read and control the parameters of the controller.
