Dual Port LNB Power Inserter

Interact with this product in a Layout Tool:

The 7702LPS-2/7703LPS-2/7803LPS-2 dual port LNB power inserter offers a modular, reliable, high performance, compact and cost effective platform for inserting DC power via coaxial cable to two LNB's. Housed in the 7800FR 3RU frame with dual power supplies, up to 30 (7702) or 28 (7703/7803) LNBs can be powered with a single frame. On their RF input connectors, the cards provide +13 / +18V DC power and 22KHz tone generation with low RF insertion loss. The 7703/7803 version includes SNMP support for remote monitoring and control via VistaLINK® software, including LNB current and RF input power monitoring.

The 7702LPS-2/7703LPS-2/7803LPS-2 occupies one card slot and can be housed in the 1RU 7801FR frame which holds up to four single or two dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU 350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.

特点|

  • Provides DC voltage of +13 / +18V DC with available +1V DC (+14 / +19V DC) cable compensation for long cable runs
  • 22KHz tone generation available on both ports for LNB control
  • DC voltage level and 22KHz tone generation are independently controllable on each port
  • Dynamic or static short circuit current protection -Dynamic mode features continuous short circuit check and automatic recovery, while static mode disables DC voltage until a reset is performed. Both modes indicate the short circuit condition on card edge LED's and VistaLINK® (7703/7803 version)
  • For system diagnostics and troubleshooting, the 7703/7803 version provides RF input power and LNB current monitoring with adjustable high/low alarm thresholds for SNMP/VistaLINK® alarming
  • 7800FR frame power supplies are redundant, front-loading and hot-swappable for reliability and ease of maintenance
  • 7702 and 7703/7803 cards are front loading and hot swappable for simple installation and maintenance
  • 7703/7803 cards feature full SNMP / VistaLINK® support and local card edge monitoring and control via the dot matrix display and toggle switch/pushbutton
