100A 2200W AC 150-220V Power Supply Delay Soft Start Board For Class A Amplifier

The function of the soft start board is to reduce the instantaneous inrush current during startup, to reduce the impact of the machine on the power grid and to extend the life of the switch. This board uses ultra-high current (100A) pure copper lead relays and large thermistor NTC 20D-20, the effective protection of the machine, to prevent excessive power-on current.
