For many years, power factor correction (PFC) has been used in applications such as

industry and energy supply for buildings to improve the quality of electric power and

make it more efficient. A major commercial benefit is the saving of energy costs. But

power factor correction also helps to decrease the current load in transmission

networks and distribution grids. By reducing the currents, net losses are lowered,

electric power is saved and CO

emission reduced. The voltage also becomes more

stable due to lower current losses, i.e. voltage drops are decreased.

This product profile is addressed to end customers, panel builders, distribution

companies and power utilities in the low-voltage power distribution sector.

Power factor correction reduces the apparent current, decreases ohmic losses,

lowers the primary power consumption and reduces costs. EPCOS is worldwide

market leader in low-voltage power factor correction.

Important Notes

The following applies to all products named in this
publication:

1. Some parts of this publication contain statements

about the suitability of our products for certain
areas of application. These statements are based on
our knowledge of typical requirements that are often
placed on our products in the areas of application con-
cerned. We nevertheless expressly point out that such
statements cannot be regarded as binding state-
ments about the suitability of our products for a
particular customer application. As a rule, EPCOS is
either unfamiliar with individual customer applications
or less familiar with them than the customers them-
selves. For these reasons, it is always ultimately in-
cumbent on the customer to check and decide
whether an EPCOS product with the properties de-
scribed in the product specification is suitable for use
in a particular customer application.

2. We also point out that in individual cases, a mal-

function of passive electronic components or
failure before the end of their usual service life can-
not be completely ruled out in the current state of
the art, even if they are operated as specified. In
customer applications requiring a very high level of
operational safety and especially in customer applica-
tions in which the malfunction or failure of a passive
electronic component could endanger human life or
health (e.g. in accident prevention or life-saving sys-
tems), it must therefore be ensured by means of suit-
able design of the customer application or other action
taken by the customer (e.g. installation of protective
circuitry or redundancy) that no injury or damage is
sustained by third parties in the event of malfunction or
failure of a passive electronic component.

3. The warnings, cautions and product-specific notes

must be observed.

4. In order to satisfy certain technical requirements, some

of the products described in this publication may
contain substances subject to restrictions in cer-
tain jurisdictions (e.g. because they are classed
as "hazardous"). Useful information on this will be
found in our Material Data Sheets on the Internet
(www.epcos.com/material). Should you have any more
detailed questions, please contact our sales offices.

5. We constantly strive to improve our products. Conse-

quently, the products described in this publication
may change from time to time. The same is true of
the corresponding product specifications. Please
check therefore to what extent product descriptions
and specifications contained in this publication are still
applicable before or when you place an order.

We also reserve the right to discontinue production
and delivery of products. Consequently, we cannot
guarantee that all products named in this publication
will always be available.

6. Unless otherwise agreed in individual contracts, all

orders are subject to the current version of the
"General Terms of Delivery for Products and
Services in the Electrical Industry" published by
the German Electrical and Electronics Industry
Association (ZVEI).

7. The trade names EPCOS, CeraDiode, CSSP, SIMID,

PhaseMod PFC Modules

General

Awareness of the necessity of pow-
er quality is increasing, and power
factor correction (PFC) will be imple-
mented on a growing scale in future.
Enhancing power quality � im-
provement of power factor � saves
costs and ensures a fast return on
investment. In power distribution, in
low- and medium-voltage networks,
PFC focuses on the power flow
(cos

) and the optimization of volt-

age stability by generating reactive
power to improve voltage quality
and reliability at distribution level.

Installing a automatic power factor
correction system provides a com-

fortable and at the actual demand
adapted solution.

The innovative PhaseMod series
represents a totally new approach in
terms of integrated automatic power
factor correction systems (EPCOS-
patented). It will replace the tradi-
tional technology of discrete switch
gears consisting of a bunch of
components such as capacitors,
copper bus bars, contactors and
fuses almost randomly chosen and
assembled onto a mounting plate
and interconnected with cables.

The forward integrated PhaseMod
family provides all the functions of

carefully selected and optimally co-
ordinated key components includ-
ing the necessary interconnections.
It improves the power quality whilst
at the same time extending the ca-
pacitors useful life by using contac-
tors with damping resistors.
