Softstarters | ABB

Motor starting matters. ABB's softstarters increase a motor's lifetime by protecting it from electrical stresses. They do so by letting you optimize starting currents that with conventional starting methods put lots of stress on the motor.

Motor Soft Starter Sizing and Applications

The motor soft starter gradually increases the voltage applied to the motor so that it can accelerate the pump up to speed without experiencing any torque or current peaks. Centrifugal pumps only have normal start capacity and a motor soft starter will allow a centrifugal pump to start at 4 .

power supply - How to limit inrush current? - Electrical ...

The USB specification chapter 11, Interoperability and Power Delivery, places rather stringent limits on power draw. The cited capacitance there is only 10µF, to avoid too much voltage drop. There are specialized ICs (like LM3525) to do both current limiting and power switching, which might help, but make sure the circuitry behind it handles the slow voltage rise correctly.

What is Software? - Computer Hope's Free Computer Help

Sometimes abbreviated as SW and S/W, software is a collection of instructions that enable the user to interact with a computer, its hardware, or perform tasks. Without software, most computers would be useless. For example, without your Internet browser software, you could not surf the Internet or read this page. Without an operating system, the browser could not run on your computer.
