3.6 Powering the DFG48044X (DC internal) with 12VDC power input
Each DFG48044X is equipped with an internal DC power supply, and has built-in screw terminals for secure
attachment of the power input leads. Three DC power models support a range of power input types. The three
DC power input terminal block choices are for use with 12VDC power. Where an AC power adaptor is used, DC
is supplied via the jack. Power input from the DC terminal block and the jack and both may be connected
simultaneously for power input redundancy.
