Product Overview

1 Introduction

This document is a general description of the power and battery backup systemPBC-02 for outdoor or indoor use that is a variant of the Power and BatteryCabinet (PBC).

1.1 Target Group

The target group for this document is network planning, site acquisition, networkengineeering, and second level support personnel.

2 Product Overview

The PBC converts AC power to �48 V DC power and can supply optionalbattery backup power to various outdoor Base Transceiver Station (BTS)products: Ericsson micro and main-remote WCDMA and GSM RBSs or BTSsproduced by other suppliers.

The standard PBC configuration consists of a PBC Main Unit (PBC-MU), seeFigure 1. Up to two PBC Battery Units (PBD-BU) can be added to the PBC-MUto extend the battery backup time, see Figure 3.

The PBC can be installed on a wall or a pole in one of the following variants:

• Single unit

• Double unit � the first PBC-BU is installed on the MU to form an integratedunit, see Figure 2. The second PBC-BU is always installed separately,see Figure 3.

The figures below show examples of PBC installation.

7.1.1 Earthing Connection Interface

Each separately mounted PBC unit must be connected to the site Main EarthTerminal (MET), using a 35 mm2 earth grounding cable. Depending on PBCconfiguration, up to three cables may be required. In case of a double unit(PBC-MU and PBC-BU) only one cable is required as the PBC-MU and thePBC-BU are galvanically connected.

The earth grounding point for a PBC unit is located on the bottom of the unit(see Figure 10), and consists of an M8 screw, a nut, and a washer.

7.1.2 Alarm Connection Interface

The PBC-MU features a single external alarm output, for alarm communicationto the RBS (or other alarm receiving system) through a single alarm cable. Incases where two PBC-MU are located at the same site and the alarm receivingsystem cannot accept two separate alarm inputs, a summary alarm from thetwo PBC-MU can be created as shown in Figure 11.

8 Power System

This section describes the power system.

8.1 Fuse Recommendations

Outdoor AC power cables connected to the PBC are fitted with either one fuse(TT and TN power systems) or two fuses (IT power systems) rated at 25 A orless for below-maximum output power

One fuse is provided on each line. After operation of the protective device,equipment is still under voltage if it is connected to a power system.

Table 17 Fuse Recommendations

Minimum Fuse Rating forSafe Function (A)

Recommended Fuse Ratingfor Safe Selectivity (A)

Voltage

MU1 MU2 MU1 MU2

230 6 A 10 A 10 A 16 A

100 10 A 16 A 16 A 25 A

Note: In power networks where a fuse is used on both the neutral and line(for example, IT networks), parts of the equipment can still be undervoltage even if one of the fuses is blown. The equipment can thereforeappear to be off but still can represent a hazard. Make sure that bothlines in the power network are disconnected before service.

8.2 AC Input

8.3 DC Output

Table 19 shows DC output values for the PBC and Table 20 shows PBC MUtype and product numbers.

Table 19 DC Output Values

Output voltage Nominal: �54 V DC

Min-Max: �43.5 to �57.6 V DC

Rectifier Capacity The PBC 02 can be equipped with one or two AC/DCrectifiers. The selection of MU type depends on the sumof the peak power consumption for all DC loads to besupported, the desired battery capacity and the ambienttemperature range.

PBC-MU1: The PBC-MU is equipped with one rectifier.The capacity is 525 W (9.6 A) above +15 �C and 600 W(11 A) in the -33 to +15 �C range.

PBC-MU2: The PBC-MU is equipped with two rectifiers.The combined capacity is 775 W (14 A) above +15 �Cand 1200 W (22 A) in the -33 to +15 �C range.

For output current limitations: see Section 8.5 on page24.

Field upgrade from MU1 to MU2 is not supported.

Maximumnumber ofconnected loads

The available output power is shared by the connectedloads. Any single output can support the full outputpower.

Surge andtransientprotection

Integrated, all four outputs

8.4 Battery Capacity

The table below shows the battery capacity alternatives for the PBC.

Table 21 Battery Capacity

Nominal voltage �48 V DC

Battery capacity • MU: 48 V/13 Ah

• MU + one BU : 48/26Ah or 48V/39 Ah

• MU + two BU : 48V/52Ah or 48V/65 Ah

The PBC can operate without batteries connected, if onlyAC/DC conversion is required.

RBS and configuration dependant. Contact your localEricsson office for more information.

8.5 Output Power Dimensioning

The rectifier capacity that is available to the connected DC loads depends on theambient temperature and the installed battery capacity in the PBC 02 system.

Table 22 shows the maximum recommended output power in order to operatethe system within the safety approvals.

(1) Component selection and design stipulate a significantly lower output power above +15 �C inorder to operate the product within its established safety certification.

Output current limitations: The start-up currents of the connected DC loadsmust not exceed 14 A (approximately 750W) for MU-1 respectively 28 A(approximately 1500 W) for MU-2. If the above levels are exceeded for morethan 400 ms, the system will shut down and require a manual restart at site.

9 Alarms

An alarm can be sent to the RBS for one of the following reasons:

• The battery lifetime has expired – maintenance personnel must visit the siteto replace batteries

• The battery has reached its end-of-discharge voltage level and will bedisconnected within a minimum of 10 seconds

• The PBC cannot distribute the required output power

• The PBC cannot provide backup power

• Hardware issues that affect the performance, for example, a temperaturesensor is broken

• The PBC is turned off
