Ports and Interfaces
Prime Power Connection
The Prime Power Connector is the point where the unit receives input power.
The AC input can operate over a range of 90 - 260 VAC, at 47 - 63 Hz. This connector is a 3
(three) pin circular connector 3100A 14S-7P and the mating connector is supplied with the
unit
Pin Circuit
A - C 110/220V (90-260V) AC
B
Ground
It’s recommended that the BUC should be powered from a 180 - 260 VAC source.
This will keep AC line currents to a safe operating level and minimizes cable losses.
In some cases, the unit may only be specified to operate at higher input voltage levels – please
check the labels or accompanying Test Record for this information.
When wiring up the mating connector, carefully follow the pin descriptions noted in the
accompanying Test Record. Incorrect connections can seriously damage the unit. It is
highly advisable that the installer checks all the pins at the AC connectors for
resistance to the chassis ground to make sure that the live and ground pins are
correctly identified .
Please contact the factory if there are any questions regarding these input connections.
RF Input
The RF Input is an N type connector. The input frequency is L Band. Nominal RF input
levels are -50 to 0 dBm, depending on the output power level and the system gain of the unit.
The maximum input level should be limited to 0 dBm to avoid damaging the unit.
Attention: This BUC Series Y does not require DC Voltages at the L Band Input Port.
DO NOT INPUT DC VOLTAGES!
10MHz Reference is required at the L Band Input .
