System Description

MCIL -WIPLL-SDN_R1_40 Marconi Communications Ltd. 8-1 of 8-16

BSPSBSPS

The Marconi Base Station Power System (BSPS) supplies the following:

• Provides off-line power to sensitive equipment

•

Charges the battery bank that provides backup power during a mains failure.

Thus, this system is essentially a DC-UPS with a battery connected to it. The

size of the battery determines the backup and charging time. Since the system is

current limited, the maximum battery size is based on that limit.

•

Monitors the operation and communicates with a PC or a host to provide full

(remote) control and indication.
