3.6 Powering the CS14 & CSN14 with 12V, 24V or –48VDC power input
Each Magnum CS14H/CS14P-Series
is reliably equipped with an internal DC power
supply, and has built-in screw terminals for
secure attachment of the power leads. Three
models support a range of power input types.
The three model choices are for use with
12VDC, 24VDC or -48VDC power. DC power
input may be chosen for high-availability.
The extended temperature capability
of the DC-powered CS14P’s can go outdoors, rated at –40`C to +75`C. If indoors, the DC
jack is also present and optionally can be used with an external AC power supply.
