Dedicated servo stabilized power supply for power amplifier
Source: InternetPublisher:赔钱虎 Keywords: Power amplifier regulated power supply AC power supply Updated: 2020/05/19
It is a set of servo -type regulated power supplies for power amplifiers . It uses two integrated voltage regulators with positive and negative outputs, 78 1 8 and 79 1 8
, and uses LF353 as the servo circuit to output three sets of positive and negative symmetrical 18v voltages . This circuit uses
a double-bridge rectifier for power supply, and the AC input adopts a two-stage AC power supply filtering and purification method, which further improves
the purity of the power supply.
