Overview
Power Supply
This unit has a non-isolated internal switcher power supply (FlexPWR). The unit will operate correctly on 10-28 VAC or 10-32 VDC. The power input is protected so power can be applied in either polarity. The supply provides the internal electronics with power with the ground of the video circuits being the same as the input power ground. The power connector is a 2-pin 2.5mm terminal block with detent retention that can support high vibration environments.
Package
The package for this unit consists of a solid epoxy block. The internal electronics are assembled and tested before the encapsulation process. During the encapsulation the printed circuit board(s) are placed in a five sided box made of RTV mold parts. The cavity is filled with epoxy and the lid (top) of the mold is inserted. The curing process takes 24 hours. This type of package seals the electronics so water and contamination cannot affect the internal electronics. This type of package also provides superior resistance to shock and vibration compared to a metal or plastic box enclosure.
Description
This product is designed to work as 20-550-001/20-550-002 (driver/receiver) to protect against ground loops and RF interference for long cable runs.
Highlights
- The driver converts a standard unbalnced baseband video signal to a balanced video signal that is transmitted over two coax cables.
- The receiver converts a balanced video signal from two coax cables into unbalanced baseband video.
- The 12VAC wall transformer provides isolated power to the Brick to control ground loops.
