Electrical testing technology

REO power supplies comply with the applicable EC directives (EN61558-2-14 or the older VDE standard 0552). Our test devices are used in test centres, development laboratories, institutes, schools and universities as well as in industry and in all mobile stations. A clean and sinusoidal current is essential for the reproducibility of the tests. Among other products, REO provides AC and DC 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.

Ohmic load units are used when power supplies or other test objects, such as switches, contacts, or Transformers, need to be subjected to an active load. Ohmic load units find their application in development laboratories, test fields, testing institutes, schools, and universities. REO load units are designed for continuous operation, feature high long-term stability, and are developed to be optimized for every current and load duration. Resistance value and power rating are specifically designed according to customer specifications.

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.

Voltage stabilisers are used as ballasts in single-phase and three-phase networks with fluctuating voltages to regulate these mains voltage fluctuations. Therefore, the consumer who is connected receives a constant voltage which results in a constant level of machine performance that is then independent from the fluctuating mains network.
