TALEMA PROFILE
The TALEMA International Group of
companies began in 1975 with the
formation of Talema Elektronik
GmbH in Munich, Germany. Five
years later, in 1980 Nuvotem Teo
started manufacturing in Ireland.
In 1988 Talema began production
in India and expanded into the
Czech Republic with the formation
of TALEMA spol s.r.o. in 1992.
Today the TALEMA International
Group, with three manufacturing
facilities and over 1000 employees
in Europe and the Far East, is a
world leader in the manufacture of
toroidal transformers and related
magnetic components. The vast
majority of the output, around 85%,
is of custom built products although
a comprehensive range of standard
devices is also available.
Note: All products manufactured by
the Talema Group are RoHS compliant.
Application
TALEMA Toroidal Transformers meet
modern day requirements for a small
size, low magnetic interference field
transformer. Featuring a nearly ideal
physical construction, the design
engineer can expect excellent
performance. Small size and weight
(approximately 50% of conventional
transformers), extremely low noise and
low magnetic interference field make the
toroidal transformer ideal for compact
power supplies. Modern production
techniques make it possible to produce
toroidal transformers at practically the
same prices as conventional
transformers making them ideal for a
wide range of applications including:
• professional audio equipment
• computers and peripherals
• video monitors
• motor controls
• compact power supplies
• medical equipment
• instrumentation
• office machines
• industrial control equipment
• low voltage lighting
Volume and weight
The toroidal core has the optimal shape
for producing a transformer with the
minimum of material. Because the
quality of the core is such a vital
consideration for sensitive applications,
TALEMA has invested heavily to provide
extensive core manufacturing, annealing
and testing facilities.
All windings are symmetrically spread
over the entire core which makes the wire
length very short. A higher flux density
is possible as the magnetic flux is in the
same direction as the rolling direction of
the grain orientated core allowing
significant savings of volume and weight
. A higher current density can flow
through the wire as the whole surface of
the toroidal core allows efficient cooling
of the copper windings.
The iron losses of the toroidal core are
very small, typically 1.1W/kg at 1.7
Tesla and 50Hz, giving very small
magnetizing current, which contributes
to the excellent temperature rating of the
toroidal transformer.
Transformer hum
Because there are no air gaps, there are
no loose sheets which can vibrate. In
addition, the high quality of the grain
orientated silicone alloyed electric steel
makes the magnetostriction very low,
thus allowing the disturbing hum found
in most common types of transformers
to be almost completely eliminated.
Mounting details
For sizes up to 1000VA, a low cost
assembly can be made with a centering washer and a center screw or bolt.
Transformers in the range of 15VA
through 500VA can also be potted in
standard Polyamid housings. All
transformers can also be center potted
- either with a center hole or with a
threaded insert.

Safety
All TALEMA Stock Transformers from
15VA to 1kVA are delivered with ENEC
KEMA marking according to EN61558
(VDE 0570, EN61558) protection class
II, tested with 4500VAC between primary
and secondary windings. Special types
can be made as safety transformers
according to EN61558. This European
Standard replaces the generally known
VDE Standard 0570. Additionally. upon
request we supply toroidals according
to conventional standards, including UL,
CSA and others, for office equipment,
data processing, entertainment
electronics and medical instrumention.
Efficiency
The toroidal shape gives a significantly
higher efficiency compared to
conventional transformers of the same
size. The advantage is either an
increased output power with the same
size or a lower weight and smaller size
at the same output power.
Internationally Recognized

Product Approvals
TALEMA-NUVOTEM has numerous
approvals covering a wide variety of
international standards, including both
standard and custom designed parts. By
working closely with equipment
designers and international test houses,
the TALEMA Groups’ engineering teams
can assist in ensuring swift and smooth
approval of equipment using its
transformers and inductors.
Family Recognitions
The TALEMA Group have invested
considerable time and effort to obtain
“Family Approvals” enabling automatic
recognition of custom transformers
without having to send each new design
to a certified test facility for approval,
saving the customer both time and
money.

In-rush Current
Due to lack of air gaps, toroidal
transformers generally have a higher
inrush current than normal transformers.
For mains fuses we recommend the use
of slow blowing types, especially for
output power rates in excess of 500VA.
Frequency Range
TALEMA Standard Transformers are
designed for operating frequencies
between 48 Hz and 60Hz and operate
up to 450 Hz maximum. With
increasing frequency, the transformer
size decreases accordingly. Core
materials for frequencies up to 100kHz
are available in materials such as thin
tape wound nickel alloy, molded powder
or sintered ferrite.
Autotransformers
An autotransformer allows smaller
dimensions and a more economical over
all design in cases where galvanically
separated windings are not required
(graph 1)
Duty Cycle
A smaller transformer can be used if the
load is intermittent. Because the output
power in this case significantly exceeds
the norminal power, the secondary
voltage drops below the voltages shown
on page 8. The voltage drop increases
proportionately with the current being
drawn (graph 3).
Efficiency
Graph 4 shows typical efficiency which
can be expected as a function of the
power relationship P out / P nom and
transformer size.

Temperature rise
As can be seen from graphs 5 and 6,
TALEMA Standard Toroidal Transformers
are designed for a temperature rise of
60°C to 70°C at nominal load. When
choosing a transformer size, the ambient
temperature and heat sink coefficient of
the mounting place must be taken into
consideration. Graphs 5 & 6 show the
typical temperature change which
occurs as a function of output power or
overload.

Voltage Drop
The secondary voltages and currents are valid as
shown on page 10 for normal output power. At partial
load the output voltage, as a function of transformer
size, will be accordingly higher. Graph 2 shows the
% voltage increase for TALEMA Standard Toroidal
Transformers at no load conditions.

Rectifying
Graphs 7 and 8 give formulas for calculation of approximate
values of the transformers and are primarily dependent on
the size of the loading capacitor to be used. The applied
form factor “F” is rated between 1.1 for smaller capacitors
and up to 2.5 for for relatively large capacitors.
