24v DC PSU module


This module uses a Simoco PRF10 SMPU regulator pcb to efficiently regulate an 18 - 35 volt
negative ground DC input down to 14.5v. Linear regulators follow this to supply:

a) 10v for the exciter module
b) 10v for the 3456MHz and 10 368MHz multiplier modules
c) 12v for the 5MHz frequency reference

The 14.5v line also feeds directly both the shelf PA and masthead PA modules.
