VACUUMSCHMELZE GmbH
& Co. KG introduces a new family of Powerline Transformers.
The new product line provides the enhanced performance required by the
standards Homeplug 1.0,
EIA 709.2, CEA R7.3, and European CENELEC EN 50065-1. The Transformers
feature outstanding
size and cost optimized designs by using advanced magnetic cores and materials.
The high performance of Powerline Transformers is a result of VAC’s superior
magnetic core technology.
Magnetic cores based on VITROVACTM and VITROPERMTM alloys yield superior
electrical performance
over the whole spectrum of transmitted frequencies. Very compact designs
are accomplished by exploiting
the highest saturation flux density of the cores. VAC’s state of the art
packaging technology is the basis
for high-quality galvanic separation that complies with all aspects of
the UL1950/ EN60950 safety standards.
In addition, VAC’s surface mount components are optimized for high-speed
pick & place manufacturing techniques.

VAC also designs components for CE BUS and X-10 applications as well as custom tailored solutions.
What is Powerline Communications?
At some point in time,
we have all thought about a smart house and running our homes with a computer.
Consider a future where all appliances, ones that have a power cord, can
be networked using universal plug and play.
This would include computers, telephones, stereos, and even refrigerators.
You could have a DVD drive in one room sending video to a TV or PC in
other, while a computer in a bedroom
could switch on your web-enabled dishwasher.
A household network
using Powerline Communications modems which connect the Internet to appliances,
will make that possible without rewiring your home.
In Powerline Home Networking, often called Homeplug, you can connect for example your computers to one another through the same outlet. Powerline networking is the cheapest method of connecting computers in different rooms, because it requires no new wiring and the network adds no cost to your electric bill.
The obvious advantage
of the PLC concept is the ubiquity of the electricity network, which is
available in every room
and almost every house in the developed world. It is denser than the existing
telephony infrastructure.
The areas of developing data transmission solutions via power lines include
outdoor (local loop) and in-house
(Home Networking, Homeplug) solutions.
Electricity, gas and
water meters can be read on-line. Alarm systems, heating and household
appliances
can be controlled over the internal power network and maintained via Internet.
Powerline is also opening up new possibilities in other areas – for instance
care for the elderly and disabled.
Although this technology
has been in use for special applications for several decades, e.g. street
lighting
is frequently operated according to this principle and the well-known
baby intercom sends voice signals over
the internal household power network, communication in these cases is
exclusively in the narrowband range
and transmission rates are correspondingly low.
For energy suppliers,
the potential inherent in Powerline technology is enormous.
Gaining direct access to end customers provides them with an opportunity
to enhance their market image
with individual, innovative offerings, and penetrate new business areas.
In view of the deregulation of
the electricity market and the associated intense pressure on pricing
and competition, this is a welcome
development as well as a new way of using existing assets at a relatively
low investment cost.
