Instant indicator
Min.setting time:15 minutes. Max.setting timer:24 hours
With hand switch,can be switched to operating and
1. Set program: 1 pin is equivalent to 15 minutes. Determine desired start time and push down pins until desired
off time.
For instance, if you want electrical devices to work from 8:00am to 11:00am and from 13:00pm to 17:00pm, you
just need to put down allthe pins between the three period time.
2. Set the current time: Turning the dial clockwise until the arrow pointing to
current time.
For example,if now it is 8:00 am, please turn the dial and make sure the
arrow point to 8. (See the picture.)
3. Plug the electrical device directly into the timer. Make sure the electrical
device is power-on.
4. Plug the timer into electrical outlet and the electrical device will be work
according to the setting program.
Note: = Normal Ope n = Timing
Make sure the switch on the Timing position. If it
is on the [Normal Open" mode, the electrical device is
always power-on and the timer function no work.

Application:
1. To enable high-power electric appliances to run automatically at off-peak time if there is different electricity
price according to different periods of time in some areas.
2. To use for electric appliances which need time control, such as water heaters, air conditioners, drinking
fountains, rice cookers, advertising lights and so on.
3. To control the charging time. For example, battery of electric bikes or mobile phones, storage batteries, etc.
4. Occasions which need switch on/off frequently, like interval spray irrigation for flowersand lawn, cyclical
adding oxygen to fish jar, fountains and so on.
5. Home safety precautions and lighting.

The first antenna of the international scientific project, the Square Kilometer Array (SKA), known as SKA-P, was officially launched today at the 54th Research Institute of China Electronics Technology Group Corporation. This groundbreaking development marks a significant milestone for China in the global race to build one of the most advanced radio telescope arrays ever conceived.
At 3:15 PM, the SKA-P antenna began its operation. With a 10-meter-high base, it slowly rotated its reflector, resembling a smart and flexible "big ear" that scanned the sky with precision. It adjusted its pitch from 15° to 90°, sweeping across the heavens, and turned horizontally up to 270°, showcasing its remarkable capability to monitor the skies effortlessly.
Liu Liehong, General Manager of China Electric Power, stated, "The successful development of SKA-P demonstrates China's leading role in the research and development of SKA core equipment and provides a world-class 'antenna solution' for international science projects."
The SKA is the largest integrated aperture radio telescope ever planned by the global astronomical community. It represents a major international science project involving over 20 countries, with scientists and engineers from hundreds of institutions working together. The SKA will be built in remote radio-quiet zones across Australia and South Africa, covering an area of about 3,000 kilometers. It will feature 2,500 15-meter-diameter antennas, creating a total receiving area equivalent to 140 football fields.
Wang Feng, Deputy Director of the SKA Office at China Electric Power, highlighted that the SKA will bring a qualitative leap in engineering and R&D, challenging our current understanding of the universe and fundamental physics. According to experts, SKA will have 50 times the sensitivity and 10,000 times the survey speed of the current largest radio telescope array, the US EVLA. Its performance is expected to remain at the forefront of astronomy for at least 30–50 years.
SKA-P, developed by the 54th Research Institute after five years of research, sets a new benchmark in antenna technology. It features a main reflector of 15×20 meters, made up of 66 triangular panels, each with an accuracy of 0.1 mm. The design ensures high sensitivity and electromagnetic shielding, allowing it to capture faint cosmic signals while minimizing interference from Earth-based sources.
Equipped with a full digital control system, SKA-P can accurately point to targets with a precision of three thousandths of a degree. This level of precision enables synchronized observations across thousands of antennas spread over 3,000 km, maximizing data collection efficiency.
With the launch of SKA-P, the SKA project has entered its construction phase. The initial stage, SKA1, involves building around 130 antennas over three years, laying the groundwork for future large-scale operations. Once completed, SKA will enable astronomers to explore the origins of the universe, search for alien life, and test fundamental theories of physics, such as Einstein’s general relativity.
As Du Fu, chief designer of the SKA reflector antennas, noted, "SKA will see farther and observe more clearly, potentially discovering new galaxies and bringing unexpected scientific breakthroughs. This will significantly advance China's research in astronomy, physics, and information technology, enhancing its global influence."
