1. The patented technology of electromagnetic voltage regulation and electronic induction can effectively solve the shortcomings of complexity and high cost of electronic ballast and reactor in lighting energy-saving transformation, and it is the first choice system for existing lighting energy-saving transformation. 2. For three-phase lighting equipment, it has the main working characteristics of stabilizing voltage, adjusting working voltage and suppressing harmonics. 3. It has complete functions, is safe and reliable, and is very convenient to install, use and maintain. 4. It can greatly reduce the power consumption of lighting equipment, and can be widely used in the environment of special energy-saving control boxes for lighting street lamps, such as offices, factories, street lamps, schools, supermarkets, community public lighting, large advertising light boxes, etc. , greatly reducing the power consumption of users and saving their operating costs. 5. The reliability is high, and the system host is made of high-quality magnetic materials, which realizes the ideal operation with low consumption and high efficiency. 6, humanized design, simple operation. 7, no harmonic interference, and can suppress higher harmonics. 8. The power saving rate is 10%-40%. 9, with low voltage automatic bypass function, automatically enter the power-saving state after the voltage returns to normal. 10, with low current automatic bypass function, reducing the power consumption of the system itself. 1 1, with automatic bypass function. 12, with manual bypass function, for emergency use. 13, two startup modes: full-pressure startup and low-voltage startup (soft start). Full-voltage start-full-voltage power supply for a certain period of time during start-up, to ensure that the lamps will automatically enter the power-saving operation state after normal use; Low-voltage starting can reduce the starting current and prolong the service life of lamps by reducing the starting voltage under the condition of ensuring the normal use of lamps. Automatically enter the power-saving state after startup. The start time is adjustable. 14, it really has a voltage stabilizing function.
