Introduction
This document describes the Power and Battery Cabinet (PBC) 6200, which
supplies power and battery backup to indoor RBSs, transmission equipment,
and other DC-operated indoor site equipment. The PBC 6200 consists of two
main parts: a power unit and a battery rack.
The battery rack can be equipped with either AGM or OPzV batteries. See
figure below.

Power Unit Overview
Product Overview
This section describes the main features and configurations of the power units.
2.1
Main Features
The power unit supplies power and battery backup to indoor RBSs and priority
loads such as transmission equipment.
2
1/1551-LZA 701 6009 Uen E | 2010-07-07
Function Description
It converts incoming AC power to 048 V DC power and distributes it through
circuit breakers to batteries and main and priority loads.
The power unit is controlled and supervised by a Control and Supervision
Unit (CSU).
2.2
Configurations
The power units can be installed on top of a battery rack or on a wall. The
Power Unit Main can be expanded with a Power Unit Extension.
The power units can be loaded up to the values given in the table below.

Power Unit
The power unit consists of the following:
3.1
•
AC power
•
Rectifiers
•
DC distribution
•
Contactors
•
Control and supervision unit
•
High-voltage protection unit (optional)
AC Power
Incoming AC cables connect to screw terminals, each of which is connected
to a rectifier.
3.2
Rectifiers
A Power Unit can be equipped with up to four or eight rectifiers, which converts
incoming AC power to 048 V DC power. Three types of rectifiers with different
output powers are available: 2000 W, 2700 W, and 2700 W High-Efficiency.
The rectifier types cannot be mixed in a PBC 6200 system.
The rectifiers are hot swappable, which means they can be replaced without
interrupting the operation of the power unit.

1/1551-LZA 701 6009 Uen E | 2010-07-07
Function Description
3.3
DC Distribution
The DC power from the rectifiers is distributed through circuit breakers to
priority load, main load, and batteries.
In the event of AC power failure the batteries supply power to both main and
priority loads.
Circuit Breakers
The power unit has circuit breakers for overcurrent and short circuit protection.
The Power Unit Main and Extension have the following positions for the circuit
breakers:
•
10 positions for main load circuit breakers
•
15 positions for priority load circuit breakers
•
16 positions for up to 4 battery circuit breakers
The PU 200A has the following positions for the circuit breakers:
•
10 positions for main load circuit breakers
•
10 positions for priority load circuit breakers
•
8 positions for up to 4 battery circuit breakers
The following table is an overview of circuit breaker types, their positions and
cables.

Contactors
The power unit has two contactors that are used to disconnect the loads from
the battery power if the battery voltage is too low to protect the battery from
deep discharge.

PBC 6200 Description
The priority load can be disconnected by a Low Voltage Disconnect Switch
(LVDS) contactor (LVDS 1). The main load can be disconnected by the LVDS 2
contactor. In the case of an extension power unit, the main load contactor is
denoted LVDS 3.
3.5
Control and Supervision Unit
The power system is controlled and supervised by a CSU.
In a PBC 6200 system with two power units, only the main power unit has
a CSU.
The CSU is the communication interface between the user and the system and
can be accessed both on-site and remotely.
It has a keypad and display for direct access on-site. It can also be accessed
through a computer equipped with the power management software supplied
by Ericsson, which can be connected to the RS-232 port on the front panel
of the power unit.
Binary Alarms Output
The binary alarms are potential-free relay contacts. The outputs are configured
as described in document PBC 6200 Software Manual. Maximum electrical
rating for each output is 150 mA/60 V DC.
Web Board (Optional)
The power unit can be accessed both remotely and on-site through an optional
web board.
3.6
High-Voltage Protection Unit (Optional)
The optional high-voltage protection unit disconnects the rectifiers from the
incoming AC power if the voltage exceeds 300 V AC.
