Spec Sheet
RSP 2150

The RSP 2150LNB Redundancy Switch provides two (2x1) L-Band sensing switches for LNB redundancy of both horizontal and vertical polarities on a TVRO satellite. In addition, it provides 24 VDC, enough to power four LNBs. Each L-Band sensing switch contains a single (2x1) RF detector switch which detects the presence of a 950-2150 MHz LNB satellite signal on the primary relay that terminates the off path with 75 Ω. The primary RF input is filtered, amplified and detected to operate the relays. When the input level is above the preset threshold, which is adjustable using the rear panel mounted push buttons, the relays are de-energized and will pass RF even under a no power condition. When the signal falls below the preset threshold, the relay is energized and the secondary signal path is selected. A front panel has been included for each sensing switch to allow manual override to the secondary input. The rear panel has been equipped with 15-pin connectors that provide an interface for contact closure alarms and remote override via contact enclosure

Features & Benefits

• The RSP 2150 LNB Redundancy Switch detects loss in signal level from LNB’s & switches to the secondary / back-up if the primary signal level falls below set threshold.

• Hot swappable power supplies to redundant power LNB’s

• LNB power feature provides two separately fused power supply modules, each capable of handling 2.5 amps.

• AC and DC power status is indicated via the front panel mounted LEDs
