100A 4000W Soft Start High Power Power Power Strip For Class A Amplifier

Description: Features:The soft-start board function is designed to reduce the instantaneous impact current to reduce the impact of the machine on the mesh and prolong the service life of the switch. This board uses an ultra-high current (100A) pure relay with copper feet and an oversized NTC 20D-20 thermistor, which effectively protects the machine from excessive inrush current. This board does not need additional power supply, only two terminals, one connected to the power input (before the control switch can be connected), output load, use very convenient. Working principle: Turn on the power supply early, through the negative temperature coefficient of the thermistor to power the load, as the thermistor temperature increases, the resistance decreases, the voltage increases slowly, Thus effectively suppress the surge current on the line impact and other electrical impact. About 5 seconds after pulling the relay, short-circuit thermistor, the power supply through the relay directly s the load power supply, it charges to the normal working state.
