Description
Description: 1.Capacitor voltage is 63V 1 million UF 2.Servo voltage regulator output voltage is + - 46V (output voltage can be customized) (There is 1% error of GND voltage ) 3.The maximum current: 2A 4. Size: 198 X 125 X 65mm The power board is the rectifier board filter,design for Class A amplifier board. because Class A power amplifier board has higher requirements of power, are generally used Voltage amplification and current amplification separately power supply,so the rectifier bridge is required to have voltage amplifier servo circuit,to make voltage output will not be affected by It will not be affected by the large dynamic fluctuation of the current amplification circuit, thus improving the stability of Class A amplifier. Recommended transformer : (only need 1pc) Note: Since the voltage amplification power supply using servo regulator circuit, so requirement of voltage is higher, if the voltage is lower than 36V, the voltage regulator circuit will fail, higher than 42V, the filter capacitor will not withstand voltage. Choice of current amplifier circuit main power supply voltage level : Class A power amplifier work in a non-linear state,voltage too high,stability will be worse, while fever also increases. So you can choose a low-voltage power supply, not only stable, but also transferred to a larger current, but the disadvantage is the power will be smaller, so users determines the voltage of the main power supply according to their own needs. Package: 1 x Class A Power Amplifier Board A8 Power Rectifier Bridge with ELNA Capacitance
