Principles of Operation
+24 VDC regulator circuit
The +24 VDC regulator circuit has approximately the same function and employs
the same oscillation circuit as the +5 VDC regulator circuit. In the +24 VDC
regulator circuit, error amplifier AMP2 is used for over-current control and AMP3
is used for constant voltage control. Figure 2-21 shows the +24 VDC regulator
circuit.
