LNB-SUPPLY/CONTROL

The LRC1142 is designed for the redundant operation of two LNBs in professional SATCOM infrastructures. Both LNBs can be powered and monitored independently. The system continuously monitors LNB current consumption and RF power and supports automated redundancy management. Additional features include the 850–2450 MHz frequency range, configurable LNB power supply (13/15/18/24 V & 22 kHz), RF power monitoring, 10 MHz reference feed, output attenuation, and control of a waveguide switch. Local and remote control are provided via the front panel, SNMP, and WebGUI, respectively.

The SLC4124 is a compact 4-channel LNB/LNA power supply and control unit in a 1RU/19″ form factor. Four LNBs can be individually powered and configured with 13/15/18/24 V and 22 kHz. In addition, the device offers LNB current monitoring, four –20 dB monitoring ports, a 10 MHz feed, and local and remote configuration via SNMP and WebGUI. A hot-swappable 1:1 redundant power supply enhances operational reliability.
