Ports and Interfaces

Prime Power Connection

The Prime Power Connector is the point where the unit receives input power. A connector

3100A 14S-7P is used.

The AC input can operate over a range of 90 - 270 VAC, at 47 - 63 Hz. This connector is a 3

(three) pin circular connector and the mating connector is supplied with the unit

AC Input Connector Pin out:

Pin A Line 90-260 VAC, 47-63Hz

Pin B GND

Pin C Neutral

Units with higher output power levels (> 50 W for Ku Band and > 100 W for C Band)

should be powered only from a 180 - 270 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 a type WR75 Flange Grooved . Make sure that a properly sized gasket is used

at the flange, with silicone paste. The input frequency is in the KU Band. Nominal RF input

levels are approximately + 20 dBm depending on the output power level and the system gain

of the unit.
