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 the customer’s requirements, the toroidal transformers are available non-cast, with centre hole casting or with full casting. Thanks to the use of UL-listed materials and various DIN-compliant mounting connections, they fulfil 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 IEC 60601-1 and IEC 60601-1-2 standards define the safety of medical electrical devices and systems. Knowledge and a great deal of experience are required to implement these standards to ensure a safe power supply.
REO isolating transformers for medical technology fulfil these guidelines and are characterised by the following features:

• 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 are free from electromagnetic interference and comply with the valid EC Guidelines (EN 61558-2-14 and the older VDE Standard 0552).
REO provides DC and AC power supplies, high-voltage power feeders and three-phase supply units that are designed for voltages up to 15 kV and currents up to 30 KA.
