What is Inrush Current?
When motors, audio amplifiers, and
power supplies are first turned on, they present high initial currents as
a result of filter capacitor impedance. |
High Current Inrush Protection
BigAmp Inrush Current LimitersSpecially designed thermistor able to withstand up to 36 amperes of continuous current and 260 joules of input energy. |
