REO is an original manufacturer of high quality power equipment, including electronic controllers, components and electrical regulators.
REO can build voltage stabilisers with up to 1MVA (3 phase) power capacity. All units in the range operate on the servo-feedback principle and use a variable transformer, buck-boost combination. There is a standard range available for single and three phase supplies, catering for different mains variation ranges. The three phase units can have common or separate control of all phases.
