Description

4*10000uF w/ Speaker Protection High-grade Power Supply Rectifier Filter Board Technical parameters: ●Main technical parameters: ●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 off the connection between the power amplifier board and the speaker, thereby protecting the speaker. 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 board adopts 2.0MM glass fiber board, copper foil thickness is 2 ounces, double-sided copper is paved, the size of the board is 111.5×110mm, four 10000UF/100V Japanese ruby or black diamond capacitors, two 104 U.S. polypropylene capacitors, rectifier High-speed MUR1620 for bridge, 20A high current relay Package： 1pcs 4*10000uF Amplifier Power Supply Board Payment Method: PayPal preferred Shippment: International shipping requires complicated shipping procedures (such as both countries customs, transit stations etc.), also will be affected by many factors, such as holidays, weather conditions etc, If you have not received your shipment after long time days from payment, please contact us.
