摘要（英）：

The fluorescent lamp/sodium lamp power economizer belongs to power saving technology. The fluorescent lamp/sodium lamp power economizer includes five circuit modules of control board power source, phase failure signal source, operation state display, SCR module and triphase AC contact module. The SCR module and the triphase AC contact module are connected in parallel; the three phase lines of power supply are connected separately to the three phase line inputs of the triphase AC contact module and the three phase line inputs of the SCR module; and the three power outputs of the SCR module areconnected separately to the three outputs of the triphase AC contact module. The power economizer has also control device and phase shifting drive board inserted for connection with the five circuit modules. The present invention has the advantages of simple structure, small size, soft starting, no contact, low cost and others
