The devices in four frame sizes enable soft starting of motors in standard applications such as pumps, conveyor belts, or fans up to 55 kilowatts at 400 volts.
The Sirius 3RW30 soft starter improves the startup characteristics of motors with two-phase polarity balancing, and avoids mechanical loads, voltage fluctuations, and current peaks. This protects not only the drive system but also the power network and thus minimizes maintenance overhead and expensive current peaks.
The user can easily set the startup time and the starting voltage using two potentiometers on the device. In the 45-millimeter frame size, the 3RW30 takes the place of a star-delta switch and saves up to 70 percent of control cabinet space while delivering the same performance power.
The device can be easily configured and installed using three motor leads and variable connections.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
