RoHS:
Restriction of the use of certain Hazardous Substances
FRIWO completely abandoned the use
of environmentally unfriendly substances;
in this transition, we have for example
implemented lead free soldering. Major
investments in comprehensive laboratory and analysis equip-
ment here at FRIWO will help us to secure such high quality
standards.
Leading position in power supplies
Continuous further development of our high-quality products,
their innovative design, and our technical expertise have made
CEAG AG/FRIWO Group a reliable and experienced industry partner
worldwide. Highly qualified, flexible employees guarantee the
quick development cycles demanded by today’s market.
The market- and customer-oriented design of the individual pro-
duct platforms, the flexible adjustment of production capacities
and the optimum organisation of the sales result in a successful
positioning on the global power supply market. Over 930 million
power supplies and chargers sold in 33 years are a clear evidence
of the Group’s high level of expertise and innovative ability.

CEAG AG/FRIWO Group
All devices are tested for operational safety in our own accredited
testing centres and leave our factories as “zero-fault products“.
FRIWO power supply and charger platforms are approved in
Europe, USA, Canada, Japan and Australia without further
testing.
FRIWO is the wholly owned subsidiary of CEAG AG. Listed in
the Prime Standard, CEAG AG is the holding company of the
FRIWO Group, with its registered office in Bad Homburg and
headquarters in Ostbevern/Westphalia. As such, it is the world’s
leading provider – through the FRIWO brand – of charging
units for mobile phones. The major shareholder of CEAG AG is
DELTON AG with almost 77 percent of the share capital.

Switchmode Power Supply
Switchmode Technology
Switchmode power supply units are particularly suited for fee-
ding portable devices. Their low weight and extremely compact
form mean they can be just as advantageously combined with all
other types of applications.
An additional increase in attractiveness results from the wide-
range input so that the power supply units can be operated all
over the world using mains voltages from 100 to 240 V AC and
50 to 60 Hz. This makes worldwide use possible and means a
drastic reduction in the logistics expenses on the part of our
customers.
Such solutions can either be realised as desktop units with world-
wide standardised IEC sockets (our DT series) or as plug-in power
supply units with exchangeable mains plug adapters (our MPP
series). Details regarding these products can be found on the
following pages.
First, here is some important technical information:
Primary Switched Power Supply Units
In such a power supply unit, the mains voltage is first rectified
and smoothed. After that, it is switched at high frequencies and
transferred via a converter transformer. The required low voltage
is then generated within another rectification and smoothing
step. A high-precision direct voltage with very low tolerances can
be provided by means of an additional stabilisation circuit.
Beyond these advantages of the compact design and wide-range
input, the high efficiency is of decisive importance: at an achiev-
able 90 percent, the losses due to emission of heat are mini-
mized. The requirements for very low stand-by power consumption
(stand-by power) can only be met using this technology.
FRIWO offers an extensive range of standard devices with excel-
lent features. At a corresponding volume, further variants for all
kinds of special requirements can be developed. In the process,
the application considerably determines the design:
■
In addition to output current and voltage, requirements
regarding control stabilisation and ripple of the output
voltage, EMC behaviour, efficiency, etc. influence the power
supply unit design.
Specific requirements regarding size and shape have an
effect on the component expense and thus the costs of
the unit.
Various circuit topologies can be used according to the
requirements.
Designs as plug-in power supply units, desktop devices, or
even as modules (= open frame) for all special applications
can also be realised.

Safety Regulations, Protection Classes, and Connection
Types
Power supply units can be found in a number of applications. For
this reason, the specific safety regulations of the devices being
powered, depending on the regulation of the testing authori-
ties of the respective countries, such as the UL (Underwriter Labo-
ratories), VDE (Association of German Electrical Engineers), etc.,
must be particularly observed.
The EMC conformity according to EN 61000-6-X, under conside-
ration of system perturbations according to EN 61000-3-2 should
be observed for power supply units independent of the switching
concept.
When selecting the housing, the ambient conditions, for ex-
ample in moist environments, must be considered. For general
applications, the type of protection according to EN 60529-IP20
(Operation in Dry Rooms – Protection Against the Penetration
of Solid Foreign Body) suffices. According to application, power
supply units are designed in accordance with the respective appli-

cable regulations. Due to the safe galvanic separation, all devices
fulfil the low-voltage guideline and provide a safety extra-low
voltage (SELV).
Exchangeable Primary Adapters
Primary Adapters
The MPP-series can be variably equipped with the mains plugs as shown.
Your applications and products can be sold and used worldwide due to the
set of all country mains plugs which can be inserted with the unit.
Mobility and dependability with respect to the use of the product are
increased in this way and provide a constant level of functionality and
availability – wherever you are in the world. Beyond that, these plug
modules help reducing the logistic complexity, avoiding the need to plan
and stock mains adapters and chargers in various mains plug configurations.
In countries with mains plugs which are not covered by EURO, UK,
USA/Japan and Australia mains plug types, the IEC adapter with the
2-pin IEC 320 C8 socket provides a standardized alternative.
