LED drivers Mean Well HLG-240H-C - 250W L

11.05.2016

Mean Well has expanded its popular HLG family of industrial and outdoor LED power supplies. Power supply models of the HLG-240H-C series with an output power of 250 W and current stabilization (with a high voltage output) are currently available.

The new HLG-240H-C series, as well as the entire HLG family, is covered by a manufacturer's warranty for up to 7 years, which indicates the high reliability of this product. Models of the new series are available for standard output currents of 700/1050/1400/1750/2100 mA, have power factor correction (p>0,95), high efficiency (typ. 94%) and a wide operating temperature range of -40°C. ..+70°С.

If necessary, HLG-240H-C models with dimming can be selected. In the new series, Smart Timer Dimming (D3; model available on request) has been added to the "standard" 1-in-2 dimming. This feature implies that the output current can be reprogrammed by the user. Several levels of output current can be programmed to be applied automatically during power supply operation. When programming, you can enable the mode of smooth current rise, LED aging compensation and other features.

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, ... >>

Earth weighed with neutrinos 31.10.2018

For the first time, physicists used data on the motion of ultralight neutrino particles to determine large-scale parameters of the entire planet Earth, including mass. The scientists also managed to obtain information about the change in the density of the medium from the surface to the core.

They are born in a variety of reactions, for example, in the center of stars, nuclear reactors on Earth, and when cosmic rays interact with the planet's atmosphere. Neutrinos interact very weakly with ordinary matter, so with a high probability they can fly through the entire planet. However, some particles are still absorbed, which can be seen due to their high fluxes. This allows you to explore the interior of the planet, since the probability of absorption depends on the energy of the particle and the path traveled.

In the new work, for the first time, physicists have been able to collect enough statistics to determine the parameters of the Earth only on the basis of data on the absorption of neutrinos. The work was done on the largest IceCube neutrino detector at the South Pole in Antarctica, which captured particles passing through the Earth. Neutrinos that appeared at the North Pole had to pass the entire planet, including its core, for registration, while those that arrived at large angles crossed only the crust. This made it possible to restore the mass distribution throughout the volume.

The new method has become an independent addition to the existing methods for determining the properties of the planet by the features of the gravitational field and based on the propagation of seismic waves, the speed of which depends on the density of the medium. The results of all methods are consistent and confirm the correctness of modern ideas and the structure of the Earth.

At the moment, neutrinos have not allowed to obtain new information about the planet, but this is not excluded in the future. For example, some models of dark matter assume the accumulation of its particles in the centers of all large bodies, and discrepancies in determining the properties of the nucleus from the gravitational field and neutrino absorption may indicate the presence of dark matter in the Earth's core.
