Features

Hot-swappable redundant power supply modules
Hot-swappable redundant combiner modules
9 dB of gain in 1dB steps via front panel mounted rotary switches
Current sensing for combiner failure
Redundant backup amplifier replaces failed amplifier in less than 1 μsec
Front panel mounted LED indicators for power supply and combiner status
Front panel mounted momentary switch for manual switching of redundant combiners
RS-422 interface for remote switching of combiner modules
50 Ω BNC termination boards for unused ports (supplied as required)
Dual AC power supply modules

Front Panel LEDs
Front panel mounted LED indicators have been included to indicate power supply and combiner status. Their meanings
are as follows:
DC Power Supply Modules
Green LED on				– normal operation
Green LED off				– power supply failure
Controller Module
AC1 / AC2
LED green			– normal operation
LED off – AC power failure
DC1 / DC2
LED green			– DC power supply operating normally
LED red	– DC power supply failure
NOTE: In those instances when the green LED goes off on a DC power supply module, its corresponding LED on the
controller module will change to red.
Combiner Modules
Green LED on (ACTIVE)						– combiner module is currently online and is operating normally
Yellow LED on (STANDBY)							– combiner module is operating normally, but is currently offline and in standby mode
Red LED on (FAILURE)					– combiner module is offline and is experiencing a failure
NOTES:		For each redundant combiner module pair, only one combiner module can be active at a time; thus, when the
		ACTIVE (green) LED is lit on one combiner module, the STANDBY (yellow) LED will be lit on its redundant
		combiner module and vice versa.
