Soft starting switch assembled heavy duty for high power/current amplifier !

This is an assembled board of a soft start switch for high power/current amplifier. The board makes use of a number of heavy duty thermistors for soft-starting function. The soft switch limits the in-rush current at the time the power amplifier is switched on. The delay time is about 3 seconds. This can prevent the circuit breaker in your home to be false triggered and protect the amplifier's internal electronics too !

This board is for 220V/240V region.
