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 test devices are used in test facilities, 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 if power supplies or other test objects such as switches, contacts or transformers must be loaded with an active load. Ohmic load units find their usage in development laboratories and test facilities, test institutes, schools and universities.
REO load units are designed for continuous operation, possess a high level of long-term stability and are optimised for every current and every load duration. The resistance value and the measurement of power are laid out, especially in accordance with the customer’s specifications.
A variable transformer is used if it is essential that output voltages are adjusted with a constant sinusoidal waveform. 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.
