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.

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.

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.

When choosing a transformer size, the ambient temperature and heat sink coefficient of the mounting place must be taken into consideration.

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. < 0.5 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.
