Section 1.4.4
The LPOD-R features a power supply that is power factor corrected. It supplies several voltages
necessary for the unit to operate:
•
The 10V power supply output state is controlled by circuitry within the RF module. If the RF
module does not have the –5.8V supply for any reason, it will not allow the 10V power supply to
turn on. This protects the power transistors within the RF module from failure due to improper
power supply sequencing.
•
The +24V output powers the cooling fans and is the source of power for waveguide switching
when the SSPA is used in redundant configurations.
•
The +5.8V, -5.8V, +7.8V and +13.5V outputs are used to operate the M&C board and other
overhead functions.
