TDK-EPC, a group company of the
TDK Corporation, has extended
its range of power factor
controllers with a heavy duty version of
the EPCOS BR6000 controller. The new
EPCOS BR6000-HD is particularly well
suited for applications that place high
demands on EMC (electromagnetic
compatibility). The new controller can
also be used in a significantly extended
temperature range from -40 to +80 °C.
This compares well with conventional
controllers, which operate across a
smaller temperature range of between -
20 and +60 °C.
The display of the BR6000-HD is also
improved: the OLED technology used
enables a high contrast of 2000:1, and
thus offers a noticeably better
readability. It displays 2 x 16 white
characters on a black background,
which are equally easily visible from a
distance, in the dark and from
unfavorable angles of vision.
Its other technical parameters and
properties correspond to those of the
standard BR6000 series. They include a
user-friendly plain text menu
(CZ/D/E/ES/F/NL/PL/PT/RU/TR), a
multifunctional display and storage of
various network and system
parameters. These features are
complemented by an intelligent control
mode and various control algorithms as
well as temperature monitoring.
The EPCOS BR6000-HD offers
automatic initialization and is available
in different versions for conventional
and dynamic PFC systems. The most
common types for conventional
systems are the six-stage controller
(BR6000-HD6) and the twelve-stage
controller (BR6000-HD12).
The TDK-EPC product range for
power factor correction includes
controllers, capacitors, thyristormodules,
contactors and chokes.

What is reactive power? |
|
Reactive power occurs whenever the phase
angle between the current and voltage shifts.
It is caused by inductive loads such as
electric motors and transformers. Reactive
power has no use, but is necessarily
generated by power plants. Reactive power
can be almost completely compensated by
connecting-in power factor correction
(PFC) capacitors. This reduces energy costs
as well as environmental impacts. |
