PS-4810   Power Supply    
12VDC Power supply from + or - grounded 48VDC sources  

Typical redundant power supply configuration

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.
