FIGURE 3-5 - DA-4X POWER SUPPLY OVERALL BLOCK
The A-board in the DA-4X chassis is identical to the A-board in the DA-4 chassis except for small mute and
protections circuits, which will be discussed later. The 120V AC input is applied to the A-board and is applied to
the STBY 5V power supply. Regulator STBY 5V is sent to the M-Board to partially power system control
IC2300, and also to the HA/HC board to power the Remote Control Sensor (SIRCS).
The Main Converter power supply for the DA-4X chassis is located on the G-board. The circuitry and the
operation of the Main Converter power supply in the DA-4X are identical to the DA-4 chassis, except for three
additional output voltages: +/- 19V, 12V and 33V, and the exclusion of the +200V line.
