3.6 Powering the ES42H and ES42P (DC internal) with 12V, 24V or –48VDC power
input
Each Magnum ES42H/ES42P-Series 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, 24VDC or -48VDC 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.
