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.

Note

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-1shows 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.
