Adjustable and constant high-current power supply for switch test benches
Description
REO high-current power supplies are used wherever test specimens need to be tested with several thousand amperes. Specifically, these include switchgear, fuses, cables, etc. The test specimens are thermally heated and tested under nominal conditions in continuous tests. Tests with defined overload curves are also performed. Traditional voltage adjustments with variable transformers ensure that the input signal is passed through to the output as a clean sine wave. This allows every test with specimens to be conducted with any current value and in a sinusoidal manner, and to be reproduced at any time. The high-current sources are electronically controlled and can achieve a control accuracy of ( 0.5%) and be integrated into the laboratory network via various BUS systems.
Advantages
- Single- or three-phase high-current power supplies
- AC power supplies up to 3x 10 kA
- Modular design of the various modules (control unit, regulation unit, power section)
Typical Applications
Heating tests of components such as cables and contacts, low-voltage distribution, switchgear with
low-impedance.
