PROmax - Weidmueller power supplies for heavy duty applications

02.09.2015

PROmax power supplies are designed in a narrow DIN-rail housing, are highly reliable (MTBF>500000 hours) and are designed for harsh environments.

The PROmax series is guaranteed to start at a temperature of -40°C, allows long-term operation at an overload of 120% and short-term operation up to 300%. The specified overload capacity allows the new series to be used to supply capacitive and inductive loads, as well as to build a system with selective load sharing using circuit breakers.

With high efficiency and well-thought-out technical solutions, PROmax series power supplies can be installed close to other system components during installation, which allows, in addition to a narrow housing, to save space.

The PROmax series is available in output power from 70 to 960 W for operation in single-phase or three-phase networks. The power supplies have a power factor correction circuit, a status relay. They also have a moderate inrush current of up to 15 A. PROmax series power supplies are designed for demanding applications in mining and process industry automation systems.

Main technical parameters of the PROmax series:

Output power from a range: 72, 120, 180, 240, 480, 960W;
Output voltage from a range: 5, 12, 24, 48 V (depending on power);
Peak overload capacity up to 300%;
Long-term overload capacity up to 120%;
Temperature range -25...+70°С (start from -40°С);
Efficiency 91% (typ.);
Power factor >0,95;
Starting current <15A.

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, ... >>

Indian village of twins 16.08.2009

Indian doctors and physiologists are investigating the reasons for the unusually high twin birth rate in the remote village of Kodinhi in northern Kerala. Officially, 250 pairs of twins are registered here, but their real number is 300-350 pairs.

There are an average of about 45 twins per thousand births, while the average for India is more than ten times lower. The phenomenon of the village of Kodinhi, according to the old-timers, arose three generations ago, and over the past 60-70 years, the frequency of twin births has been increasing.

Researchers believe that the reason may lie in some natural substances obtained by local residents with water or food. In any case, contamination with chemical waste can be ruled out, since children are born perfectly healthy and there are no industrial enterprises nearby.
