TT Welwyn : Current Sense (2)
A Line Input Resistor is typically a fixed resistor connected in series with the mains input of a power supply.
It serves to (a) limit inrush surge current at switch on. (b) Contribute to lightening surge protection. (c) Prevent fire by fusing safely.
Data Sheets are shown where available.
