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.

PTC Thermistors vs. NTC Thermistors for Inrush Current
Prevent Inrush Current with PTC and NTC Thermistors PTC and NTC thermistors can provide inrush current protection in various equipment, machinery, and systems. Inrush current affects a wide range of products, from transformers to motors, and electronics from power supplies to inverters. Inrush current becomes further complicated by systems that switch on and off quickly, such as welding equipment and HVAC systems. This post will give you a brief overview of … Continue Reading
Inverter Pre-Charge Circuit Inrush Current
Pre-Charge Circuits Prevent Damage to Inverters Severe damage can occur to inverters when the inrush current is too great for the inverter. Pre-charge circuits protect the inverters by controlling the initial power surge. PTC thermistors can help a pre-charge circuit protect the inverter. Inrush current occurs when the maximum instantaneous input current flows through a system when the electrical power is switched on. In power tools, such as power drives, … Continue Reading
How To Limit DC Motor Inrush Current
Choosing An Inrush Current Limiter To Preserve Your DC Motor So, what does an Inrush Current Limiter have to do with DC motor inrush? More than you may think. DC motor inrush is the maximum, instantaneous input current drawn by the DC motor when first turned on and it is important to know how to limit the inrush current to prevent possible damage to the motor. A DC motor converts … Continue Reading
