DEV 8120 Managed LNB Powering and RF Monitoring System

DEV 8120 Managed LNB Powering and RF Monitoring System

The DEV 8120 Managed LNB Powering System provides centralized LNB power, current supervision and RF signal monitoring for satellite ground stations, teleports and broadcast facilities. Its standard 3 RU chassis accommodates 16 twin modules for up to 32 LNB channels and can be expanded to 27 modules for as many as 54 channels.

Each short-circuit-protected channel supplies 15.5 VDC at up to 500 mA and provides adjustable upper and lower current-alarm thresholds. When all 54 channels operate simultaneously, the average current must remain at or below 320 mA per channel to maintain power-supply redundancy.

Optional integrated RF monitoring routes any selected channel to a front-panel monitoring port. The DEV Web Interface, SNMP, Ethernet and RS-232 connections provide convenient remote configuration, monitoring and alarm reporting.
