New Solid State Relays International Rectifier

16.06.2007

Compared to its peers and predecessors, the PVN012A family has half the AC on-state resistance (Rdd(on)) and 37,5% higher AC load capacity at 100% duty cycle.

The new relay series is also rated for the maximum impulse (overload) current. With low channel resistance and high current carrying capacity combined with a compact housing, the PVN012A relays outperform traditional electromechanical relays.

They occupy a smaller area, are rated for high isolation voltage between input and output, have a stable open resistance throughout the entire service life, high sensitivity and high reliability, and are free from contact bounce.

The new relays are rated for 20 V, with an on-state resistance of 50 mΩ AC and 15 mΩ DC. The current carrying capacity is 4 A AC and 6 A DC. The insulation test voltage between input and output is 4000 V. The new relays are available in lead-free 6-pin DIP and SOIC packages and on tape.

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, ... >>

Link between hunger and mood revealed 03.10.2018

Researchers at the University of Guelph have shown that the sudden drop in glucose we experience when we're hungry can affect our mood.

“We found evidence that changes in glucose levels can have a lasting effect on mood,” said psychology professor Francesco Leri. “I was skeptical when people told me that they become grumpy if they don’t eat, but now I believe it.” "Hypoglycemia is a strong physiological and psychological stress."

The scientists studied the effect of a sudden drop in glucose on emotional behavior by causing hypoglycemia in rats.

"When people think about bad mood and stress, they are talking about psychological rather than metabolic factors," said MSc Thomas Horman, who led the study. "But we found that bad eating behavior can have an impact on mood."

The rats were injected with a glucose metabolism blocker, causing them to experience hypoglycemia, and then placed in a specific chamber. Then several rats were injected with water and placed in another chamber. When given the choice of which chamber to enter, the rats actively avoided the chamber where they experienced hypoglycemia.

"The avoidance behavior in this case is an expression of stress and anxiety," Lehri said. "Animals avoid this ward because they had a negative experience and they don't want to experience it anymore."

The researchers performed a blood test on rats after the onset of hypoglycemia and found elevated corticosterone, which is indicative of physiological stress. In addition, rats treated with a glucose metabolism blocker became lethargic and lifeless.

"You could argue that they need glucose to get their muscles to work," Lehri said. "But when we gave them conventional antidepressants, the sluggish behavior disappeared. behavior changed."

This finding supports the idea that the animals experienced stress and depressed mood in the hypoglycemic state.
