In the process of power transmission in the power supply department, in order to avoid the voltage loss and the voltage caused by the peak of power consumption, the lighting power saver is generally used to increase the voltage transmission, so the voltage actually consumed by the user is often higher than the rated voltage of the equipment. These excess voltages not only fail to make the load operate more efficiently, but also cause excessive waste of electrical energy, increase equipment damage rate, and increase cost and other negative effects.
The intelligent lighting saver optimizes the input voltage of the power supply system by electromagnetic induction. The AC-AC direct conversion technology is used to adjust the voltage, and the voltage input to the light load is the optimum value, which achieves both power saving and lighting standard requirements. purpose.
According to the basic principle of electrician P=U2/R, the voltage applied to the luminaire is U, and the impedance of the light is set to a fixed value R. Then, the power consumed by the original voltage U0 is P0, and the voltage is appropriately reduced to U1. The power consumed by P1 will decrease with the square of the voltage. Its active power saving rate is expressed as:
ε%=1-(U1/U0)2×100%
