2082-142 Redundant Unit Controller 1:2
The Model 2082-14X Redundant Unit Controller is used to power, monitor and control LNA or LNB amplifiers configured in 1:1 (2082-141) or 1:2 (2082-142) redundancy. Front panel LEDs indicate power, status (online, standby, alarm), and mode (auto, manual, local, remote). Up to 600 ma is available to power each amplifier and 26 VDC or 47 VDC for -47 version is provided for 1:1 (3A) or 1:2 (3A) waveguide switch drive. The Model 2082-141 has 26 or 47 volt common and the 2082-142P has ground common. LNA or LNB current is measured and a fault is signaled if the current deviates from user selected thresholds. Multi-function switches select Auto, Local, or Remote operation, priorities for 1:2, and the signal path in the Manual mode. Remote operation via the RS232/RS485 M&C interface allows selection of priorities (1:2) and the signal path. Ethernet is available as option, -W8, -W18, or -W28. Contact closure to ground inputs allow selection of Local/Remote, and Auto/Manual Modes. An LCD display shows each amplifierʼs current, and signal path. Form C relay contact closures indicate amplifier and power supply status, waveguide switch position, Auto, Remote, and Manual operation. Connectors are DB37 for contact closure I/Os, MS3112E16-23S for the amplifier plate signals, and DB9s for monitor and control and auxiliary external contact closure alarm inputs. The 2082-14X is housed in a 1RU chassis and is powered by redundant power supplies fed by separate, fused 100-240 ±10% VAC AC input connectors.
