Power Supply Modules are offered to handle:
• ac or dc input power
• low power (250 W) or high power (500 W) station requirements
A high power Power Supply Module (500 W) is used in a station with a high power Power
Amplifier Module (e.g., rated at 100 W or 75 W output power).
A low power Power Supply Module (250 W) is used in a station with a low power Power Am-
plifier Module (e.g., rated at 40 W output power), or if the station is configured as a Satellite
Receiver.
The 250 W models generates the +5.1 V and +14.2 V operating voltages for the station mod-
ules.
The 500 W models generates the +5.1 V, +14.2 V, and +28 V operating voltages for the sta-
tion modules.
These modules have power factor correction and include a connection for battery backup.
