ElectricalTest Solutions

Electrical test systems for test laboratories, workshops, schools and universities

REO develops and manufactures electrical testing equipment for standardized design of the devices of our customers.
The production takes place according to the machine directives, specific standards for other countries can be considered.

The construction of the plant and equipment is modular so that later adjustments can be made to increase the power.

For the commissioning of your electrical appliances, a 100% inspection must be relized - with the REOLAB laboratory and endurance test devices you'll find the ideal solution.

Secure testing without EMC problems

Complete high voltage and high power test stands with sinusoidal output belong to our versatile program as well as individual variable transformers, which are the origin of our work, too. True to the motto: "From the variable transformer we have learned it."

We deliver also the necessary load units (resistive or inductive), and current-, voltage- and power regulators or regenerative systems.

As a special service we offer risk assessments according to the machine directives, which are available on demand for our products.
From test systems for relays up to railway converters - with REO you find the right solution!
