The new REOLAB 1000 E is an electronic DC supply designed for lab and test operation.
Precise and stepless voltage and current values can be internally and externally predefined. Long-term tests can be programmed via profiles and logged via internal logic.

Operation
All parameters can be set and correspondingly read off by means of a large LCD panel.

• 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.
