Astronomical Timer Based Street Light Controller

The ATS-ST-6A is an Automatic Street Light controller based on Astronomical time. Local Sunset and Sunrise time of the city is automatically calculated internally. Seasonal variation of Sunset & Sunrise time is accurately calculated by the advanced digital controller and is used to switch the street light ON and OFF Helps saving energy bills for service providers. Can be used for Garden light, Security light, Campus & Estate light etc not effected by dust deposit or bird drop unlike photo sensor based controllers.

  • Automatic Dusk to Dawn operation
  • Simple & easy fitment
  • Can fit inside most Streetlight Luminary
  • Operates on the City’s local dusk & dawn time
  • Overvoltage protection for lamp
  • Very Low Power Consumption
  • Single solution for up to 400W lamp
  • Not effected by bird droppings or dust
  • The SH series is an advanced TRUE Solar Power Conditioning Unit (PCU) offering unique and powerful features.
  • The load is automatically powered either from the Inverter or the Grid depending on the availability of Solar Energy and status of battery. Similarly charging happens by solar charger or grid charger depending on battery charge status and availability of solar energy. Solar charger always takes priority over grid charger.
  • It has two modes of operation- SOLAR mode to minimize electricity bills and NORMAL mode to maximize power availability.
  • The Inverter output is a highly regulated and stable pure sine wave which can be used for any type of sensitive and expensive electronic equipments. It can run any domestic loads like incandescent bulbs, CFL lamps, fluorescent lamps, halogen lamps, fans, mixers, blenders, food processors, TV, music system, DVD player, personal computers etc.
  • High efficiency SMPS based Inverter
  • MPPT solar charger with dynamic tracking points.
  • Data logging based on Real Time Clock(RTC)
  • Wi-Fi connectivity with PC/ Laptop through local Router to dump log data
  • Provision for remote disabling of output
  • IGBT based high frequency inverter
  • Multi-function LCD display for status and fault annunciation.
  • High level of protection from overload, short-circuit, over-temperature, battery low and battery overvoltage, reverse phase at output.
  • Speed controlled cooling fan operation to optimize cooling based on loading
  • Low standby loss of <6W
  • Suitable for PC, Laptop, Projectors, Printers, Modem, Audio systems, Routers

  • What is the typical efficiency of a High frequency SMPS based Inverter and a transformer based one?
    Efficiency of 90% and above are achievable in a High frequency SMPS based Inverter. Whereas transformer based design can achieve about 70% efficiency. To get higher efficiency, the transformer has to be over designed making it costly
  • Why is efficiency important in solar application?
    Not only in solar, efficiency is important in all application. Efficiency is the figure of merit of the inverter. It indicates the percentage of power delivered at the output from the input power drawn from the DC Battery. This power loss is wasted inside the inverter as heat. If you notice large heat-sink or more number of cooling fan or if the temperature of the air thrown out by the cooling fan is high then efficiency is poor.
    This power wasted is every day and is direct loss in terms of money.
    In specific reference to solar, it is to be noted that the input power comes from the solar panel. Solar panel is the costliest part of a solar installation. Therefore it is bad economics to waste solar energy inside the inverter. The other way of looking is that if an inverter has 20% higher efficiency, then we need to install only 20% less PV panel for the same performance. Or we can get 20% more output for the same PV panel.
