A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

DRE120 and DRE240 are compact, efficient DIN rail power supplies 05.05.2016

Chinfa has developed compact and efficient 120W and 240W DIN rail power supplies. The new series of power supplies DRE120 and DRE240 have increased efficiency (efficiency up to 93%), high peak overload capacity (up to 150%), active power correction circuit (l>0.95) and the possibility of parallel operation to increase current (parallel operation is selected by a switch) .

The power supplies are operable in the industrial temperature range from -40°С to +71°С. Products are available for two output voltages 12 and 24 V, and in models with a voltage of 24 V there is an additional relay for remote control ("dry" contact). The DRE120 and DRE240 have a set of protective measures against short circuit, overload, overvoltage and overheating, and in terms of electromagnetic compatibility, they comply with the requirements of EN55022 class B (CISPR22-B).

Given the high overload capacity, it is possible to implement selective low voltage protection in the system. New series of power supplies are designed for industrial automation systems, as well as other systems operating in a wide temperature range, where there are requirements for the efficiency and quality of the supply voltage.

Main technical parameters of DRE120 and DRE240 series:

Output power 120 and 240 W
Output voltage 12 and 24 V
Input voltage range 88-264V (AC) / 120-375V (DC)
Efficiency up to 93%
Power factor l>0,95
Overload capacity up to 150%
Ability to work in parallel mode (up to 3 pcs.)
Temperature range -40°С...+71°С
