Wireless Master Clock

GPS Based Wireless Master Clock Model No: SWDC105M Our wireless synchronized master clock system operates on a very basic concept. The Master clock acquires the time and then transmits it wirelessly to the slave clocks that are in the system. Once the transmitter master clock receives a time update, it then transmits the time to any number of secondary slave digital clocks. The digital clocks need only a 240 VAC power outlet. They include their own internal battery pack with 5 year life. Global Positioning System (GPS) is a radio-navigation system available to the worldwide.  A fleet of 24 satellites orbit the earth broadcasting their position coordinates and highly accurate time code, GPS signals.  Each satellite is equipped with atomic frequency standards they are widely used for time synchronization, frequency calibration, and navigation. This system receives signals via satellite and constantly updates the time displayed on the clock.  In the event of a power failure a battery takes over which is automatically recharged once power is restored.  In the event of longer power failures the clocks will automatically fast advance to the correct time. This system is used widely in public and time critical applications where a reliable maintenance free solution is required.
