    Description

    4*10000uF High-end Power Supply Rectifier Filter Board With Speaker Protection
    Parameter:
    ●Input voltage: AC 42V + 0 + 42V
    Output voltage: DC: ± 55V
    The power board also has a speaker protection circuit, which is mainly served by the C1237 application specific integrated circuit. This protection circuit can prevent the speaker from being burnt due to the normal operation of the power amplifier circuit. The relay will not be closed immediately when the power is turned on. It is closed after a delay of one to two seconds. When the midpoint voltage of the power amplifier board is not 0, the relay will be disconnected immediately, cutting away the connection between the power amplifier board and the speakers, thereby protecting the speakers. When the DC level of the power amplifier board returns to normal to 0, the relay will close immediately, and the sound will work normally.
    ●The power supply board adopts 2.0 MM glass fiber board, copper foil thickness 2 ounces, double-sided copper paved, the size of the board is 111.5 × 110mm, 4 100 00UF/100V capacitors, two 104 capacitors, high-speed MUR1620 for rectifier bridge, 20A large current relay.
