3 Toroidal Transformers for Universal Application Application TALEMA Toroidal Transformers meet modern day requirements for a small size, low magnetic interference field transformer. Featuring an ideal physical construction, design engineer can expect outstanding and excellent Performance.Small size and weight (approx. % of the 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 ideo monitors Motor controls Compact power supplies Medical equipment Instrumentation Office machines Industrial control equipment Low voltage lighting olume 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 syetrically 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. Tesla and Hz, giving very small magnetizing current, which contributes to the excellent temperature rating of the toroidal transformer. 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. 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 coon types of transformers to be almost completely eliminated. Mounting Details For sizes up to 1, a low cost assembly can be made with a centering washer and a center screw or bolt. Transformers in the range of 1 through 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 Production program Standard Distribution: Open wound, Standard and Mini; Encapsulated; Print & DIN Rail Transformers - primary, with ENEC KEMA-KEUR marking Customer standards: Open wound, Encapsulated, Print, DIN Rail, a wide range of secondary voltages and mounting styles Specials: As per customer specification : K per Phase Special Sizes; extremely flat or small diameter, i.e., upto 2 with 96 O.D for European P.C formats Electrostatic copper shielding Operating frequencies up to 2KHz Assembled 3 phase sets Magnetic shielding Potting in special housings for sizes upto 1.2K voltage available upto1k 3

5 In-rush Due to lack of air gaps, toroidal transformers generally have a higher inrush current than normal transformers. For mains fuses we recoend the use of slow blowing types, especially for output power rates in excess of. Frequency Range TALEMA Standard Transformers are designed for operating frequencies between 4 Hz and 6Hz and operate up to 4 Hz maximum. With increasing frequency, the transformer size decreases accordingly. Core materials for frequencies up to 1kHz are available in materials such as thin tape wound nickel alloy, molded powder or sintered ferrite. Auto-Transformers An autotransformer allows smaller dimensions and a more economical overall design in cases where galvanically separated windings are not required Graph 1 (Autotransformers) U max.

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 partial loads. Graph 2 (oltage Drop) % oltage Drop [] Toroidal Transformers for Universal Application 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 given. The voltage drop increases proportionately with the current being drawn. Graph 3 (Duty Cycle) Pnom < P load t 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 and 6, TALEMA Standard Toroidal Transformers are designed for a temperature rise of 6 C to 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.
