Adjustable And Constant Voltage Supplies

• Output Current: 10 - 100 A

Applications:

This is the ideal answer for every laboratory requiring a variable voltage source with manual or automatic adjustment and simultaneous voltage stabilization.

• 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 supplyies are used wherever DUTs, with several thousand amperes have to be tested,
particulary 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 any time.

The control of the high-current supplyies is electronically performed with the result that an accuracy of < 0.5% is achieved.In addition, the control can be integrated into custemers laboratory networks via different BUS systems.

Applications:

For endurance tests up to 5 kV, the high-voltage supply with galvanic isolation provides the entire power supply for test fields of quality assurance.

Equipment:

•     Circuit breaker with magnetic and thermal tripping in the mains input


•     Main contactor for switching the transformers in operation

REO develops and manufactures with the series REOLAB 420 the ideal test system for the DC supply of railway or wind converters for higher power ratings.
The REOLAB 420 test system is designed according to the machinery directive ; railway and and wind converters up to 600kW can be tested and documented via the REO Powerformer .

For the series REOLAB 420 we supply electrical or compressed air operated switches. The grounding circuits are constructed in such way that the capacitor in the intermediate circuit is switched off.

On request we will send you the exact operating instructions and technical description - or you can make an appointment with our technical engineer!

Options :

• AC output


• UPS for emergency stop operation


• Compressed air short-circuit mechanism


• Forced air cooling ( water cooling )


• Risk assessment
