11.5. Power Supply
Switching AC-DC power supplies are used to power the amplifier pallets, the control circuits, and all of
the fans. The DC system voltage is set at either 28 or 48Vdc nominally, depending on the system. All
fans run off this same DC supply. The specific DC system voltage is found in the Final Inspection Report.
AC is fed into the power supply enclosure via a filtered AC entry and then through a circuit
breaker/switch. Specific AC current draw is documented in the Final Inspection Report. AC is then
converted to DC using one or more AC-DC switching power supplies.
The following is the switching power supply data sheet(s) used to convert the AC
to DC for the internal amplifier or transmitter components
Depending on the unit purchased power supplies may change:
TXF-2000: RSP-2000-48 x2
TXF-3000: RSP-2000-48 x3
TXF-5000: DRP-3200-48 x3
