Power Supply Components
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 24, 30,
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,
and the model and number of power supplies, is documented in the Block
Diagram supplied in the Quickstart package.
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 supplied in the Quickstart package. 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.
