Parallel Gate Amplifier

The standard DC bus voltage is +28 VDC, but the PGA module is capable of handling

DC bus voltages up to +100 VDC, if required by the application. Voltages greater than

the standard +28 VDC must be provided by an externally mounted power supply,

connected to the Power Supply module’s P/S 2 and COM faceplate terminals. See

chapter 3.

The PGA module has one internal fuse. The fuse is not user-serviceable. A blown

fuse indicates that the PGA module has failed and must be replaced.

A functional block diagram of the PGA module is provided in figure 4.2. Specifications

are listed in Appendix C.
