Mean Well LED drivers with Smart Timer Dimming

25.10.2016

Mean Well has introduced a series of programmable LED lighting power supplies with a new Smart Timer Dimming feature. The new range is based on the low cost and reliable ELG family.

The Smart Timer Dimming function provides the ability to program the desired dimming profile with smooth transitions, the ability to program the required constant output current in the range of 10-100%, the ability to compensate for LED aging and obtain a stable light output throughout the life of the lamp, as well as several adaptive dimming options . In this case, you can set or select a self-adjusting dimming profile for changing seasonal daylight hours.

Additionally, it is possible at any time to forcibly turn on the power supply to the maximum output current. The drivers have a control of the total operating time and indication of resource depletion.

Using the programming function, you can set a smooth increase in the output current at the moment the power source starts, which will favorably affect the life of the LEDs and the power supply at the time the line is turned on.

The Smart Timer Dimming function will remove the dependence on LED binning, unaccounted for losses in the secondary optics and ensure an accurate luminous flux of the luminaire.

Power supply models are currently available in series from 75 W to 240 W (ELG-75, ELG-75-C, ELG-100, ELG-100-C, ELG-150, ELG-150-C, ELG-200 , ELG-200-C, ELG-240, ELG-240-C). The presence of the Smart Timer Dimming function is indicated by the ending D2 in the name of the power source.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Cow toilet 15.07.2023

Scientists from Germany decided to teach cows to use a special toilet. They believe this could help farmers reduce water pollution and reduce greenhouse gas emissions.

Cow dung can be a problem, especially if they are in stalls where urine and feces are mixed. Because it produces ammonia, an indirect greenhouse gas.

The experiment was carried out on a farm run by the Research Institute for Farm Animal Biology in Dammerstorf. Researchers Lindsey Matthews and Douglas Elliff of the University of Auckland said that the training was carried out according to the principle of "carrot and stick". To do this, they set up a special area called MooLoos, lined with artificial grass, where cows can safely urinate without endangering the environment.

At the first stage, the calves were driven into the MooLoos in turn and rewarded with food if they did their "easy job" there. The next step was to increase the distance to the toilet. If there were "accidents" in another part of the barn, the cows were sprayed with water. Quite quickly, 11 out of 16 calves were toilet trained.

Cows self-initiated toilet entry, producing an average of 15 to 20 urinations. And at the end of three-quarters, the animals were doing three-quarters of their urination in the toilet.

If in Germany the cows are mostly in barns, the next step is to see how the system will work in the context of New Zealand, where cattle spend most of their time in open units.

However, the animals are collected for milking and supplementation, so during this time they could use a special toilet. In addition, they can be installed outdoors. And even if such an approach is not very successful, scientists are convinced that it would still have significant environmental benefits.
