Overview
The clock is an intelligent quartz clock for construction, mainly used in stations, squares, docks and high-rise buildings to make your building more beautiful and practical. The main functions include travel time function, timekeeping function, microcomputer monitoring, GPS correction, power failure compensation function and night lighting function. Various tower clocks can be referenced to the external standard time source as the system travel time reference. The diameter of the tower clock is usually 1 to 10 meters, and the diameter of the disk can be customized according to customer needs.
Feature
1) Time indication function: three-needle (or two-needle) time indication of hour, minute and second hand.
2) Intelligent drive function: The number of drive plates is 1-32, and the disk surface diameter is 1-10 meters.
3) Automatic calibration function: The sub-master clock system adopts closed-loop control, and the movement feedback time condition is automatically calibrated.
4) Automatic chase time function: After the system is powered off, the memory unit automatically memorizes the sub-clock data, and automatically catches up to the standard time after the call within 6 months.
5) Intelligent timekeeping function: Automatic high-fidelity CD sound quality music time, using standard British Big Ben music, timekeeping content can also be customized. Automatic timing turns on and off the time amplifier. The timekeeping power is: 100-600W, which can be customized.
6) Intelligent lighting function: Automatically turn off the lighting device.
Choose from three lighting methods:
a, LED lighting: the use of wide viewing angle LED light-emitting diodes, the night scene effect is excellent. The lighting life is over 100,000 hours. Available colors: red, yellow, green. Users can also customize special colors: blue, white, etc. The clock hands are inlaid with illumination.
b. Fluorescent lighting: Philips three-color pure white fluorescent tube is used, and the lighting effect and life is much higher than ordinary fluorescent lamps. The entire interior of the clock face is illuminated.
c, metal halide lighting: Osram double-ended metal halide lamp, color temperature 5200K, super bright pure white lighting. The overall illumination of the clock face.
7) Security function: The working voltage of the whole system is 12V DC safe voltage supply, providing users with effective security.
8) Maintenance-free function: The whole tower clock system has reasonable design, long service life and no manual maintenance.
Application
The clock can be put on any place like office building,school building,playground,government office and other public area.
