INTERESTING FACTS ABOUT TRANSFORMERS
The amount of energy consumed is significantly reduced by using an REO toroidal transformer. In a comparison between a traditional transformer and a toroidal transformer, the losses can be reduced by up to 40%.
REO toroidal transformers possess a low magnetic stray field and very low intrinsic losses. They can achieve a reduction in weight of up to 50% as a result of their special construction. For use in aggressive environments, the toroidal transformers are equipped with a special full-bonded grouting. With the use of UL-listed materials and various DIN-compliant fastening connections, you will fulfil the very highest quality standards.
A variable transformer is used if it is essential that output voltages are adjusted with a constant sinusoidal wave form.
The REO variable transformers create no interference or harmonics and are therefore particularly suited for use in test facilities or research institutes, where high frequency interference could falsify the results.
The IEC60601-1 Standard and EU Guideline 93/42/EEC define the level of safety for medical electrical systems.
A lot of knowledge and experience is necessary to implement these standards to guarantee a safe power supply.
REO medical transformers fulfil these guidelines and distinguish themselves for the following reasons:
- Low stray field – a high level of EMC compatibility can be guaranteed as a result
- High strip quality − for a high level of effectiveness and outstanding performance
- Full grouting - as protection against mechanical influences and for better heat dissipation
REO leakage transformers filter harmonics and therefore ensure a limiting of the ripple current.
Due to the spatial separation of the primary and secondary windings and the targeted enlargement of the magnetic stray field that is linked to it, a loose magnetic coupling is achieved with the REO leakage transformer. In this way, the function of a transformer (voltage transformation and galvanic separation) and a sinusoidal filter choke are combined.
Particularly in the railway sector when the highest possible level of comfort and safety for the passengers is important, space-saving, safe and long-lived components are essential.
REO power supplies and free from electro-magnetic interference and comply with the valid EC Guidelines (EN 61558-2-14 and the older VDE Standard 0552). REO test devices are used in test facilities, development laboratories, institutes, schools and universities as well as in industry and in all mobile stations.
