The 12VAC Brick™ is designed to function properly with an input power of 11-13VAC.
The Brick will not operate from a DC voltage. A 2.1mm P5 style connector is used for the power input. If
the input voltage is a grounded system, the center pin of the P5 is the power connection and the barrel is the
ground side. All ProSeries units are shipped with a 12VAC, 600mA floating power supply that eliminates any
ground loops through the power supply connection.
The FlexPwr Brick™ is designed to function properly with an input power of 10-28VAC
(ungrounded) or 12-32VDC (grounded or ungrounded). A 2-pin header (Phoenix Contact #1881448) style
connector is used for the power input. The 12VAC, 600mA wall transformer provided with the product provides
a floating power source that has been designed to eliminate any ground loops through the power supply
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.
