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!

REOLAB 220
Variable and constant high-current supply Test station for switching devices
- Input voltage: 230/400 V / 3 x 230/400 V
- Output voltage: 0...10 V / 3 x 0...10 V
- Frequency range: 50/60 Hz
REO high-current supplies are used wherever DUTs, with several thousand amperes have to be tested,
particularly switching devices, fuses, cables, etc.
The test items are thermally heated and tested in long duration tests under nominal conditions.
Tests with defined overloaded curves can also be made.
Traditional voltage adjustments with variable transformers ensure that the input signal is passed through to the output as a clean sinus.
Thus, tests with any current value can be sinusoidally tested and reproduced at anytime.
The control of the high-current supplies is electronically performed with the result that an accuracy of < 0.5% is achieved. In addition, the control can be integrated into customers laboratory networks via different BUS systems. -
