2.3. Rectifiers
Fig. 2-5 APR48-3G Rectifier
Powerware APR48-3G Access Power Rectifiers are designed specifically for network access
applications such as cellular base stations, customer premises equipment and road-side cabinet
installations.
The new generation 3G architecture is reliable, power dense and compact.
The APR48-3G rectifier incorporates a combination of leading-edge high frequency switch mode
technology for a flexible and efficient DC power source, with high reliability fan cooling which further
contributes to its high overall reliability.
The APR48-3G is a high powered rectifier with 1800W output. It is designed for operation at up to
70°C (158°F) and under a wide range of AC power conditions.
These features make the APR48-3G perfectly suited to the wide variety of equipment and demanding
environmental conditions found in network access applications.
The APR48-3G has power factor correction, (up to 92% efficient), with optimum performance available
at typical load currents. Together these give the APR48-3G some of the lowest running costs for any
DC power system of its type available.
Operating with the Powerware SC100 or SC200 system controller, the APR48-3G rectifier modules
will provide years of cost-effective, and trouble free service for your 48V network access equipment.
2.3.1. Outline Rectifier Technical Specifications
AC Supply 220/240V, 50/60Hz (nominal) 175-275V full output power up to 50°C [122°F]

2.4. SC200 System Controller
Fig. 2-6 SC200 Controller
The SC200 system controller is an advanced control and monitoring solution which provides a full
suite of communications options, including built-in Ethernet interface, Web server, and SNMP agent.
Alarm notifications may be by SNMP traps, SMS text messaging, dial-out to PowerManagerII remote
monitoring software, or relay contact closures.
The SC200 is supplied pre-configured with either a default configuration file, or with one factory
customized for a particular application. Some configuration file changes can be made with the keypad,
or all settings can be changed via a PC connected to the USB interface (see details on page 8).
For connector pin-outs see document no IPN 997-00012-50, SC200 System Controller Operation
Handbook.
For Troubleshooting regarding the SC200 alarm LEDs, see document no IPN 997-00012-50, SC200
System Controller Operation Handbook.
2.4.1. Input/Output Board
The input/output (I/O) board provides the system I/O interfaces and connections for the SC200 system
controller.
The I/O board includes a range of sense inputs for dc power system control and monitoring. It also
allows real time data collection from building services and other external devices, and relay outputs for
alarm signals or control of external devices.
The I/O functions are:
Sensors: Current - 3, Bus voltage - 1, Temperature - 2, Battery Mid-point - 4
Input/Output: Digital inputs: 4 pre-defined system functions, 6 user-defined
Relay outputs: 6 (one also used as Monitor OK alarm)
LVD contactor outputs: 2
For input and output specifications see document no IPN 997-00012-50, SC200 System Controller
Operation Handbook.
For connector pin-outs see document no IPN 997-00012-50, SC200 System Controller Operation

The Power Supply Unit is mounted directly on the floor.
3.1. Cabinet Position
1. Clearly identify the area where the equipment is to be installed.
 Refer to the site documentation/job pack to verify cabinet position, as layout can change.
2. Measure up as per supplied floor plan and mark cabinet positions.
3. Ensure that the floor surface where the equipment is to be installed is level.
4. Ensure that the floor surface where the equipment is to be installed, and any areas over which the
equipment must be moved, are sufficiently strong to take the weight of the cabinets and the point
loading of the transport mechanism.
 The mass of the cabinet is given in Cabinet Dimensions and Mass on page 74.
5. Ensure that all areas of floor are protected from damage by the transport of the equipment. Use
hardboard or a similar material. This material must be removed once installation is complete.
6. The installation area is clean and dry.
3.1.2. Positioning
No space is necessary at the sides or rear. In locating the equipment, the following must be
considered:
1. Allow distances from other equipment as required by the installation requirements of that equipment
(although the Power Supply Unit does not require space at the sides or rear, adjacent equipment
may do so).
2. Bear in mind the space required for door opening. The minimum recommended space is 840mm.
the doors are removed by opening to 45º and lifting off the hinges.
 The doors are right opening (hinges on the right hand side).Do not open the door beyond 90˚
otherwise damage to the door/hinge may result.
3. When installing on a raised "Computer floor", locate the first cabinet over one tile. If load spreading
is required due to cabinet weight then this must be installed prior to cabinets being installed.
 The cabinet sizes are given in Cabinet Dimensions and Mass on page 74.
4. The cabinet is suitable for mounting on concrete or other non-combustible surface only and is to be
fixed to the building floor.
5. The cabinet must be positioned in a room with restricted access.
