1. Welcome
The Flatpack2 rectifier module is a powerful and cost-effective power supply used in
Eltek’s Flatpack2 DC power system.
About this Guide
This booklet provides users of Flatpack2 DC power systems with the required information
to install and operate the Flatpack2 rectifier modules. The booklet also presents the
rectifier’s technical specifications, such as input voltage range, output power, operating
temperature range, etc.
Read also the generic and site specific documentation that was delivered with your
Flatpack2 DC power system.
System Diagram ⎯Flatpack2 DC Power System
The Flatpack2 rectifier modules are the building blocks of Flatpack2 PS systems, see
Figure 1. The Smartpack controller monitors and controls the whole system, and serves
as the local user interface between you and the system. The PowerSuite application
enables you to configure and operate system from a personal computer.
Figure 1 Example of a typical Flatpack2 PS system for DC power supply of telecom
equipment. The system is fed from an external AC mains supply, and consists of
rectifiers in power shelves, a control unit and DC distribution unit. Battery banks,
LVD contactors, etc. are typically also a part of the system.

2. Flatpack2 Rectifier
The Flatpack2 rectifier module is a hot-pluggable, digitally controlled switch mode power
supply. The module is designed for battery charging and supplying of high quality DC
power to telecom equipment and similar applications.
The rectifier works in stand-alone mode or in parallel with other rectifiers, then
communicating via CAN bus with the system’s Smartpack controller and other connected
rectifiers. Flatpack2 DC power systems are implemented by mounting the rectifiers in 23”
or 19” power shelves (5 or 4 rectifiers across, respectively).
A wide range of features are implemented in the Flatpack2 rectifier, as mentioned below.
Key Features
Highest efficiency in minimum space
Resonant topology makes the module efficiency industry leading, and
contributes to the rectifier’s ultra compact dimensions.
Digital controllers
Primary and secondary controls are digitalized, enabling excellent
monitoring and control characteristics. Also, the number of
components has been reduced by 40% compared to previous rectifier
generation - for highly reliable, long life, trouble free DC power
systems.
Heat management
Front-to-back air flow, with chassis-integrated heat sinks, gives the
module the most suitable working environment and no limitations in
the scalability of the desired system solution.
CAN bus networked
The Flatpack2 rectifier is connected in a CAN bus network for
communication with the controller and other rectifiers.
Unique connection
A true plug-and-play connection system: reducing time-to-install
related cost.
Global approvals
Flatpack2 is CE marked, UL recognized and NEBS certified for world
wide installation.
Typical Applications
Wireless, fiber and fixed line communication
Today’s communications demand state-of-the-art, cost efficient and compact DC power
systems. Flatpack2 rectifiers deliver industry leading power density and superb reliability
at lowest lifetime cost.
Broadband and network access
Increasing network speed demands flexible and expandable DC power solutions. The
Flatpack2 rectifier is your key building block for future needs.

3 Installation of Flatpack2 Rectifiers

3.Installation of Flatpack2 Rectifiers
Safety Precautions
Get acquantied with the satety precautions on page 2, before installing or handling
the equipment.
Mounting and Removing Rectifiers
The Flatpack2 rectifiers incorporate handles that serve both to lock the modules
into position and to pull them out of their housings.
Mounting the Flatpack2 rectifier (hot-pluggable)
1. Open the handles
(insert a screwdriver into the holes to release the
spring mechanism)
2. Insert the module fully into the power shelf
3. Lock the handles
(push the handles up into their housings (locked
position), so that the module is securely locked)
Removing the Flatpack2 rectifier
1. Open the handles
(insert a screwdriver into the holes to release the
spring mechanism)
2. Remove the module
(use both handles to pull the module loose from the
connector; support from underneath)
Figure 2 Flatpack2 rectifiers’s locking mechanism
Removing Blind Panels
Release the panel’s upper left and right corners by inserting a small screwdriver
into the panel’s upper left gap, and carefully press down and out to release the
locking tabs. Repeat on the upper right gap. Refer to the Flatpack2 system’s quick
start guide for more information.

CAUTION: The rectifiers may be warm, but do not hand-carry them by their

CAUTION: Do not relocate already hot-plugged rectifiers to other positions in
the power shelf.
New Flatpack2 rectifiers must be hot-plugged in the power shelf, one at time,
starting with position 1, 2, 3 and so on. This is usually performed before shipment
of the system. Read your system’s quick start guide for more information.
CAUTION: Double Pole / Neutral Fusing. There is a Mains fuse in each line.

3 Installation of Flatpack2 Rectifiers
User’s Guide Flatpack2 Rectifier Module, 350002.013, v5-2006-11 7
Connections
All connections are implemented by inserting the Flatpack2 module fully into the power
shelf, thus plugging the rectifier to the self’s back wiring card (hot-pluggable).
Figure 3 Flatpack2 module’s rear plug-in connections to power shelf’s back wiring card
For details about other power shelf signals, type of power shelf, etc., please read the
system’s generic and specific documentation, or contact your dealer or Eltek
representative.
CAN Bus Addressing (plug-and-play)
When a Flatpack2 rectifier is hot-plugged in the power shelf the first time, the Smartpack
controller automatically assigns the rectifier with the next available ID number (CAN bus
address).
The rectifier will retain its ID (and serial number), even after removing and reinserting it
in the power shelf.
The rectifiers’ IDs are assigned from 1 and upwards. When a module is plugged in, the
Smartpack controller automatically increases the number of communicating rectifiers in
the CAN network.
Correct Rectifier Position in Power Shelves
Flatpack2 DC power systems are usually shipped from factory with the rectifier modules
already installed in the correct position in the power shelves, with respect to their CAN
bus address or ID number.
This relationship is very important for the correct monitoring of the mains three phases,
as the Smartpack controller always uses rectifier ID 01, 02 and 03 to monitor mains
phase L1, L2 and L3 respectively. If these rectifiers malfunction, rectifier ID 04, 05 and
06 will automatically take over.
For example: accidentally inserting a rectifier with ID 02 in a power shelf position
internally connected to mains phase L1, will cause the controller to monitor L1 “thinking“
it monitors L2.
