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 protection for LED lighting retrofits can be key to a successful lighting upgrade. Retrofit of LED lighting into an existing electrical system relies on the equipment already in place. This can be problematical due to the high inrush current created by the LED drivers. Falling LED prices and immediate energy savings are propelling the upgrade of older lighting modalities to new LED lighting for commercial and institutional users. For facilities management, benefits of a … Continue Reading
Large power users require mitigation of inrush currents as part of overall energy management strategy. Industrial automation with motor drives and logic controllers, high voltage power supplies feeding industrial robotics and solar panel arrays with large capacity power inverters all require inrush current limiting. Overview Inrush current is the momentary surge of current created when power is turned on to motors, transformers, power supplies and heating elements. … Continue Reading
We couldn’t keep it a secret any longer. Finally, a UL approved circuit protection thermistor (Inrush Current Limiter) that’s just 12.3mm in diameter but packs an energy rating of 40 (J), yes; we said 40 (J) plus a maximum continuous current rating of 6.0A. Meet our upgraded UL certified SL12 10006 for limiting inrush current. We think this device is a game changer! Up until now if an application required … Continue Reading
