Insu Intelligent street light controller works on Green technology

  • Up to 52% energy saving
  • Reduce carbon foot print
  • Effective public service
  • Track your energy consumption day by day
  • Street lighting management at your finger tip
  • A great software tool for maintenance management
  • Increase luminary life - thanks to hawk eye protection system
  • Easy installation – replace existing feeder pillar…
    and that’s all
  • Works on low cost GSM communication

Street Light Controller communication

Over view of the System

  • Intelligent street light controller is installed in place of existing feeder pillar.
  • Street light monitoring and Control System starts working with normal power ON.
  • Controller switch on/off the connected street lighting as per astronomical parameter programmed.
  • Controller moves in to energy saving mode as per the programmed parameter and in co-relation with the in – coming power parameter.
  • Controller protects the system by tripping the individual fault phase as per programmed protection parameter settings.
  • Controller can restore the tripped phase by its auto resetting features or by acknowledgement of the alarm.
  • Street light remote monitoring and control system sends message to and alarm (in case of GSM option) on the following events: (All configurable)
    • On / Off / energy saver starts
    • Faults like Over/ Under Voltage, Over current, Short Circuit & internal faults which is useful for diagnostic
    • PF low, Neutral open etc

Functional Description:

  • System operates on Sun rise and sunset timing – saves 4% to 8% of energy
  • In normal functional time system corrects voltage if goes beyond certain limit– saves additional 7% to 10% energy
  • At low traffic time (programmable) system enters in to energy saving mode – saves additional 45% to 50% of energy
  • At mid night or very low traffic time staggering starts (programmable) – additional 7% to 10% energy saving
  • At early morning when traffic starts, staggering disabled (programmable)
  • At Dawn (considering civil twilight time) system switch off the power
  • Insu energy saver gives you substantial energy saving by optimized burning time and staggering / dimming at off peak traffic hours
