DESCRIPTION
As it’s name implies, the Power Amplifier, Power Supply supplies power to the RFL 9508 Power Amplifier.
There are two different types of Power Amplifier, Power Supplies available as shown in Table 9-2.
The 9508 Power Amplifier, Power Supply is a dual output, dc to dc converter. It is a switching power supply
using pulse width modulation. The 107254-4 operates from 38 Vdc to 150 Vdc, and the 107254-5 operates from
200 Vdc to 300 Vdc. Each supply has two outputs, +30 Vdc @ 0.25 Amps and +95 Vdc @ 2.4 Amps. Both
outputs are connected to a common ground. A block diagram of the Power Supply is shown in Figure 9-6.
