DEV 8122 & DEV 8123 L-Band LNB Power Supplies, 2 or 4 Channels

DEV 8122 & DEV 8123 L-Band LNB Power Supplies, 2 or 4 Channels

The DEV 8122 and DEV 8123 LNB Power Supplies provide reliable LNB power and RF signal distribution for two or four L-band channels in a compact 19-inch, 1 RU chassis. Each channel includes an integrated 1:2 splitter, providing two DC-blocked RF outputs so the secondary output can feed a monitoring system.

Both series supply 15.5 VDC at up to 500 mA per channel and are available with 50 Ohm SMA or 75 Ohm precision F female connectors. The controlled DEV 8123 additionally provides per-channel current monitoring, adjustable upper and lower alarm thresholds, front-panel alarm LEDs and dry-contact alarm reporting.

Redundant AC power supplies and two-stage power-failure alarms provide dependable operation in satellite ground stations, teleports and broadcast facilities.
