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
The 87-Series composite video switches are feature rich devices configurable to operate using several different modes of operation.
Highlights
- Modes include; Basic switch functions, Timed switching function, and Automatic switching functions. Models with 8 inputs or more have an integrated 1×2 DA (two outputs)
- A multi-color LED (green/orange/yellow) provides power status and an indication of the selected option during power-up
- The USB port permits the user to change configuration parameters and store the changes into the internal non-volatile memory as the power up default setting
- The internal power supply is fully isolated to permit the user to control ground loops
- Power and control connectors have an integrated threaded/screw flange for shock and high vibration environments.
