SDK-9 latitude and longitude intelligent street light controllerDetailed product description：

The SDK-9 intelligent street lamp controller adopts the most advanced computer control technology from abroad, using the operating laws of the sun and the earth, as well as the relationship between the earth's longitude and latitude and sunrise and sunset. Based on the seasonal changes, the longitude and latitude algorithm is applied to calculate the sunrise and sunset time. It also has the functions of fine adjustment of switch time and midnight control, which can adapt to the needs of different geographical environments. It is the best time controller for street lamps, advertising light boxes, neon lights and other equipment; It can be widely used in all places that require time control, such as streets, railways, waterways, industrial and mining areas, schools, and power supply departments.

Features
1. Adopting advanced foreign microprocessor chips, high reliability, small error, and strong stability.
2. With power-off data protection, the clock works continuously without the need to replace the battery, maintaining the clock's operation for more than ten years.
Group 0 working mode: The lighting time can be set by the user, ranging from 00:00 to 23:59; The turning off time can be set by the user, ranging from 00:00 to 23:59. The switch time is the same in the same month, but different switch times can be set for different months.
4. One set of all night working mode: Control the on/off time according to latitude and longitude, and adjust it reasonably with seasonal changes. The on/off light time is automatically adjusted every day, and there is a fine adjustment function for the on/off time, ranging from -50 to 50. Turn on/off the light in the negative direction in advance and delay it in the positive direction.
5. One set of midnight working mode: Control the turning on time according to latitude and longitude, and the turning off time can be set by the user, ranging from 00:00 to 23:59, which can effectively save energy.
⒍ It has automatic/manual conversion, which is convenient for the maintenance of electrical equipment or the needs of major celebrations.
Strong anti-interference ability, high-power relay output, can be connected to 220V or 380V contactors, with a long service life.
