System description PODS 16.48-16000 1940 HEX
4.1 General
PPS 16 modular DC power cabinet systems are designed to meet rigid telecom applications with very high
reliability and flexibility for future expansion. This cabinet power solution provides rectification, system
management and power distribution while maintaining high reliability and offering flexibility for future
expansion. The PPS 16 Power Systems are based on hot-swappable rectifier modules (FMP 16.48) with
output power available at 1600W per module. Systems are also based on fan cooling rectifiers and it is
therefore important that the ventilation panels are kept free from dust and obstructions that may prevent the
air circulation.
System management is accomplished through messages and alarms displayed on the system controller’s
(PCS) LCD screen and can also be displayed remotely via the PC-based PowCom™1software package.
Note! Normally rectifier modules are installed in the cabinet at shipment, but in some particular cases
rectifier modules are shipped separately.
Note! Before Commissioning and Maintenance are carried out a PC with PowCom installed must be
connected to the RS232 contact.

4.3 Operation
zThe PODS 16.48-16000 HEX is capable of delivering up to 16000W/48V steady state power. The
system is based up on hot swappable 48V/1600W rectifier modules, which are working in parallel
with automatic load sharing.
zThe cabinet system is normally configured with N+1 redundancy, with N as the number of rectifier
modules necessary for feeding the load and charging the battery and 1 as the redundant rectifier
module. In normal operation the rectifier modules, FMP 16, are feeding the load and simultaneously
maintain the batteries in a fully charged state.
zDuring a mains input power failure, the rectifiers are shut down and the batteries deliver the power
required by the load, for a certain backup time. If the battery voltage drops below the pre-set level,
the low voltage disconnection circuit (LVD) disconnects the batteries automatically to prevent battery
deep discharge prolonging the battery life. When the mains input power is restored, the rectifiers
start up automatically feeding the load, closes the LVD circuit and begin to recharge the batteries.

zThe system performance is supervised and controlled from the supervisory unit, PCS. From this unit
output DC voltage is set, alarm thresholds, LVD circuit operation, temperature compensated battery
charging and battery testing. Any malfunction will be indicated by LED, text in the display and
operation of dry contacts. However, PCS is not a single point of failure. In the event of malfunction in
the PCS, basic tasks like feeding the load and charging batteries, will be maintained by the rectifier
modules directly at preset default values.
zThe alarm and threshold setting of the PPS 16 can be set locally by using the PCS push buttons and
menu guided operation or remotely, by using the PowComTM software.
4.4 System Description - PPS 16
This system consists of the following components:
Figure 4-3 Front view of PPS 16.48-16000
4.4.1 FMP 16- Rectifier Module
The Power-One FMP 16 rectifier provides extremely reliable DC power in the highest possible density. The
module incorporates the latest in power monitoring solutions through an internal microprocessor, giving up
to the second updates to the system controller and adjacent rectifiers, guaranteeing tightly controlled load
sharing among rectifiers, and providing status and identification information to the controller.
Other features include 3xLED for rectifier status indication, thermal protection with de-rating and input over
voltage disconnection with automatic reset. The rectifier units are hot swappable and can be quickly
removed and replaced without disrupting the system or load.
See: 9 Product Description FMP 16 on page 9-1
4.4.2 PCS - Controller System
PCS - is a supervisory system with onboard software for monitoring and operation of power supply systems
based up on Power One rectifier modules. The design is based up on the philosophy of having one main
controller supervision for the entire power supply system, and use of distributed intelligence by local micro
controllers. A RS485 data bus takes care of internal communication between the various units. RS232 is
used for remote operation from a PC.
PowComTM software
PowComTM is a communications software package that allows the remote control of the power supply
system. The software uses a Windows based interface to allow access to the PCS. PowComTM is installed

on a remote PC and can access the system by either direct connection, a LAN, or through a dial-up
modem.
Power-One Network interface (option)
The Power-One Network Interface (PNI) is an optional component, that allows the PCS unit to be remotely
accessed via Ethernet and SNMP. The SNMP protocol allows enhanced managing capabilities and
enables the system to be accessed from any location. The protocol uses simple commands to configure
and control the system and relay the system status to the operator. Using this monitoring ability allows the
alarm messages to be transmitted to any location. The PNI also can be used in conjunction with
PowComTM software either through a modem or Ethernet connection.

4.4.3 PPR 16/10 23”- Subrack
PPR 16.48 is a subrack for modules in the FMP 16 series. The subrack has up to ten module positions
(max. 10xFMP 16 rectifiers.) The subrack has a connection for AC in, DC out and RS485 for
communication.
Modules are “hot swappable” under full load conditions.
See: 10 Product description PPR 16/10 23” Subrack on page 10-1
4.4.4 PBDU 23” - Distribution Module
DC distribution module with battery breakers, load breakers, shunt for measurement of current, alarm for
battery and load.
The distribution has no special operation other than switching the battery and load breakers on and off. All
DC distribution breakers are supervised by measuring voltage drop across each breaker.
Breakers that are not connected to any load, will not cause breaker alarm even if they are left open.
Note! Due to a small leakage current (2,5-3 mA) through the alarm circuit the voltage measured with a
DVM (Digital Volt Meter) on an open breaker output, will be nearly equal to output rectifier
voltage.
If a battery breaker fault occurs or is simulated it may take from 2-10 minutes before the fault is indicated,
depending on the battery condition.
The distribution module has common "+" and breakers in "-" leg. For more information see schematic
drawing in Appendix A.
See: 7 Product description PBDU 23”
4.4.4.1 Low Voltage Disconnection (LVD)
The system is equipped with low voltage battery disconnection, which prevents the batteries from deep
discharging, thus prolonging the battery life. A disconnection requires a detected mains failure at the
supervision unit. Threshold for disconnection is available.
If disconnection occurs, the batteries will not supply power to the load until they have been recharged to set
voltage level, which can be adjusted by the user.
If disconnection occurs, the batteries will be reconnected when mains supply return.
4.4.5 Cabinet Door With Heat Exchanger (HEX)
The Cabinet door is a lockable door meant to protect the battery compartment from access of unauthorised
personnel. The system heat exchange unit is also mounted in the door.

Figure 4-4 Cabinet door with HEX, inside view
The principle of the Heat Exchanger unit is to use cool ambient air to cool down the warm air inside the
cabinet, without any ambient air being pulled into the cabinet itself. Two fans pull outside and inside air
respectively through each side of the heat exchanger element. The fan speed is monitored by the controller
and is decided by a temperature sensor positioned by the internal air inlet (see Figure 4-4). Figure 4-5 on
page 4-8 shows external air flow, internal air flow and a principle drawing of the heat exchanger element.
