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. Depending on customer requirements, the toroidal transformers are available non-potted, with center hole or fully potted. By using UL-listed materials and various DIN-compliant mounting connections, they meet the highest quality requirements.

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 fulfill these guidelines and distinguish themselves for the following reasons:

• Low stray field – which ensures high EMC compatibility
• High-quality belt quality – for high efficiency and excellent performance
• Fully encapsulated – 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 offers AC and DC power supplies, high-voltage power supplies and three-phase power supplies designed for voltages up to 15 kV and currents up to 30 KA.
