12VDC Power supply from + or -
grounded 48VDC sources
The LiteLink® PS-1260 is a stand-alone or rack mountable
power supply that is specifically designed to provide an isolated 12VDC 1
Amp output from common -48 VDC telecommunications power sources. Both the
inputs and outputs are fully isolated from each other (and from
ground) making the unit ideal for a wide range of applications.
The PS-4810 has integral power, overload and alarm indicators. Internal
fuses protect the unit in the event of an overload and will automatically
reset when the overload condition is removed. The power supplies have the
ability to be paralleled for redundant operation.
