This system, for single phase, will switch on electrical lights connected with it when natural light gets darker and will switch off the said lights automatically as soon as natural light brightens up. This way the system not only saves a lot of electric energy and manpower but also prolongs the life of Lamps/LEDs. The system is very useful for Park Lights, Glow Sign Boards & Hoarding etc. with switching contact (inrush/start up) current load capacity up to 4000 Watts for Lights with filaments which is approximately 400 Watts for LED Lights. IMPORTANT NOTE: Contact current load of 4000 watts (Max.) is for normal lights with filaments. In case of LED lights with drivers, calculate Inrush/Startup current (consumed for charging internal capacitor in drivers) which is much more (depending on the manufacturer, model, efficiency and quality of such drivers) than the continuance current rating (watts) mentioned on LED lights. Inrush current load can be found in datasheet of LED Lights. Therefore, please check and calculate current load accordingly before attempting to purchase or install it.
