Inrush Current Solutions
Inrush Current Limiters are used to reduce the inrush current that occurs when an electrical device is switched on. High inrush current is the result of the maximum instantaneous input current drawn by an electrical device during the initial power up. As technology continues to advance, most systems today run efficiently and maintain a low impedance which in turn contributes to high inrush current.
Additionally, devices that produce alternating current such as electric motors or transformers can draw several times their steady state current at switch on. Although this additional draw of inrush often lasts less than ½ of a normal 60 hertz cycle, that is enough time to cause possible damage to the equipment.
Inrush current can cause considerable damage to electrical applications. It is important to control this starting current with the right inrush current limiter. In this article we look at what can happen when you choose the wrong circuit protection device. Then we demonstrate how to choose the right circuit protection device. Finally, we show the dramatic difference between using an inrush resistor and not using one in a vacuum motor. … Continue Reading
There is a lot of information available about inrush current limiters and their different applications, capabilities, limitations, and other particular details. But very infrequently is the most basic question asked, what is an inrush current limiter and why is it used? To access, appreciate, and apply the benefits and solutions that these components provide, it is important to first be able to understand, acknowledge, and answer the question of what … Continue Reading
Regulating Inrush Current at Powerup At powerup, DC/DC converters draw a large amount of electrical current. This inrush current can be fatal to both the converter and the load if not controlled at the beginning. To achieve a soft start, when the electrical current rises gradually to its specified level, the use of an NTC Thermistor Inrush Current Limiter can be vital. DC/DC Converters DC/DC converters transform a source … Continue Reading
