    ●Control switch is suitable for self-locking and self-resetting type

    ●Two protection normally open protection interfaces

    ●The product weight is 230g

    ●The rated current of the relay is 30A, which can withstand the power below 1000W.

    ● PCB board is 2MM high-grade fiberglass board

    ●The copper foil of the PCB is 2 ounces

    ●The size of the PCB is 77.5MM*88MM.

    ●The distance of four symmetric holes is 69X79.5MM

    ●The product weight is 230g

    ●The rated current of the relay is 30A, which can withstand the power below 1000W.


    The main function:

    Suppress the inrush current of the power amplifier at startup, because the power of the class A and high power amplifier transformer is large, the load impedance is extremely low, and the capacity of the power supply filter capacitor is too large, resulting in excessive current of the power amplifier when the power is turned on, which easily damages the rectifier bridge and the damage filter capacitor.

    When the temperature of the power amplifier board heat sink exceeds 75 degrees, the board can immediately cut off the power supply, and the power amplifier will not be overheated and burned. Until the temperature of the heat sink drops below 75 degrees, the power amplifier can be turned back on, otherwise the power amplifier can't be turned on.
