LRS-PS-FEED Power Supply
B.1 Functional Description
LRS-PS-FEED is a standalone power supply unit designed to serve as a source of
remote (phantom) feed power.
LRS-PS-FEED is intended for use in conjunction with modules equipped with a
remote power feeding interface, e.g., HTU-E1C/P, installed in the 24-Card
HDSL/Modem Hub with SNMP Management, LRS-24. The remote power feeding
interface of such modules enables the supply of feed voltage to the remote
equipment connected to the module through standard twisted-pair lines. Each
interface can provide up to 60 mA per output line.
LRS-PS-FEED has one output, terminated in a short cable with a five-pin connector
that can be directly connected to the Phantom Feed connector on the
LRSI-PSP/230/115 or LRSI-PSP/48 interface module.
LRS-PS-FEED is available in two versions:
• AC-powered version that can operates on 115 VAC or 230 VAC
• DC-powered version that operates on –48 VDC.
LRS-PS-FEED is intended for installation in 300 mm and 600 mm ETSI racks, as
well as in ANSI and 19" racks. Unit height is 1U.
When used with LRS-24, the LRS-PS-FEED should be installed above LRS-24.
B.2 LRS-PS-FEED Panels
AC-Powered Unit
Figure B-1 shows the front panel of the AC-powered LRS-PS-FEED unit. The front
panel includes a power switch, a Power indicator that lights when the unit is
powered, and a standard 3-pin IEC AC input power socket with integral fuse.
The output voltage (Phantom Out) is provided by means of a short cable
terminated in a five-pin connector.
