NN Lite Planner

NN PROJECTSIn order to meet the growing requirement for increased productivity and reduced pollutant emissions, governments & non-government bodies from all over the world have understood & identified not only the need for improved energy efficiency, but also the hindrances that sometimes hold manufacturers back from investing in new technology.

The solution is an intelligent lighting power-saving device that promises new power-saving concept on gas-discharge lighting. Our intelligent lighting power-saving device NN LITE adopts advanced electromagnetic voltage regulation and automatic phase balance technologies to vary voltage in real-time mode while it improves extra power consumption of lights due to imbalance loads in supply circuit. It is applicable for power-saving purposes in a variety of gas-discharge lighting systems, including high pressure Sodium vapor, high pressure Mercury vapor, Fluorescent tubes incandescent bulbs, metal halide lamps. Its power-saving efficiency may reach 25% - 45%, without much effect to light output.

In respect to gas-discharge lamp/tube, at start-up moment, it needs enough rated voltage to activate the electrons inside for 5 to 7 minutes so as to enable the lamp/tube to produce light. Within preset time, NN LITE automatically regulate load voltage after it detects that the power to lamp/tube have been released completely.

Moreover, gas-discharge lamps switches to power-saving mode while NN LITE enters auto-online voltage detection state. According to different configurations of original devices in user's lighting system, its power-saving efficiency may reach 25%-45%.

Features of NN LITE
Intellectualized automatic control system.
  • It can effectively stabilize voltage and realize dynamic optimization in various modes to make sure optimal power-saving effect.
  • It can ensure 25% or more of power-saving efficiency when in normal condition.
  • Safe bypass control in device ensures a stable supply of current to fluorescent tube in case of system failure.
  • Intelligent voltage induction function can prevent fluorescent tube from suddenly becoming yellow or dark.
  • Power-saving level may be set according to user's requirement.
  • 100% full automatic switch-over function.
  • Reduces fluctuatons on lamps because of optimal voltage stabilization & hence increases the life of the lamp by atleast 30%.
Effectively extend service life of electric light source.
  • Reduce working temperature of lighting equipment and effectively filter current fluctuation and impact to provide protection function for the equipment.
  • Visibly extend service life of electrical equipment; also service life of light fixture may be extended to 30%.
  • Improve safety performance of equipment and decrease fault occurrence frequency.
Low risk and high return investment that substantially reduces the operating cost.
  • Sound price performance ratio reduces 10-40% operating cost.
  • Payback period for the investment will be one year or less.
  • Designed operation life of NN LITE Planner may reach 100,000 hours. After the payback on investment, user can enjoy the entire cost saving for the remaining operation life. Reduce working temperature of lighting equipment and effectively filter current fluctuation and impact to provide protection function for the equipment.
Easy installation.
  • No limit on the number of NN LITE Planners installations.
  • Connect to electrical equipment in series while it is directly connected to the circuit of power supply system of fluorescent tube.
  • No circuit modification is needed; simple modification and easy installation.
  • No increase in overall harmonic wave in circuit.
  • Some advantages such as good outlook, compact structure, easy operation, safety and reliability as well as low maintenance cost.
Scope of applications:
Our intelligent lighting power-saving device is applicable to the sites where large quantities of fluorescent tubes equipped with induction ballasts are used.
