Quintech RLS 1750A Redundant L-band Splitter offers Hot Swap Amplifiers & PSUs. Quintech RLS 1750A Redundant L-band Splitter is Based on Quintech’s RPS series redundant power supplies and the LS2150 series L-band splitters, the RLS48 1750A provides an active 48 way redundant splitter operating over the 950-1750 MHz frequency range.
Features
Hot-swappable redundant power supply modules
Hot-swappable redundant splitter/amplifier modules
10 dB of gain in 1dB steps via front panel mounted rotary switches
Current sensing for splitter/amplifier failure
Redundant backup amplifier replaces failed amplifier in less than 1 μsec
Front panel mounted LED indicators for power supply and splitter/amplifier status
Front panel mounted momentary switch for manual switching of redundant splitter/amplifiers
RS-422 interface for remote switching of splitter/amplifier modules
Dual AC power supply modules
Front Panel LEDs
Front panel mounted LED indicators have been included to indicate power supply and splitter/amplifier 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.
Splitter/Amplifier Modules
Green LED on (ACTIVE) – splitter/amplifier module is currently online and is operating normally
Yellow LED on (STANDBY) – splitter/amplifier module is operating normally, but is currently offline and in standby mode
Red LED on (FAILURE) – splitter/amplifier module is offline and is experiencing a failure
NOTES: Only one splitter/amplifier module can be active at a time; thus, when the ACTIVE (green) LED is lit on one splitter/amplifier module, the STANDBY (yellow) LED will be lit on its redundant splitter/amplifier module and vice versa.
