Alimentaciones de tensión regulables y constantes

fuentes de alimentación de alta tensión de ca y cc, alimentaciones de corriente trifásica y equipos de laboratorio de REOLAB

Las fuentes de alimentación de REO están libres de perturbaciones electromagnéticas y satisfacen las directivas CE vigentes (EN 61558-2-14 o la norma VDE más antigua 0552).

Los equipos de comprobación de REO se utilizan en campos de ensayos, laboratorios de desarrollo, institutos, escuelas y universidades así como en la industria y en todas las estaciones móviles. Para la reproducibilidad de las comprobaciones es indispensable una corriente sinusoidal limpia. REO ofrece, entre otras cosas, fuentes de alimentación de tensión de CA y CC, fuentes de alimentación de alta tensión y fuentes de alimentación de corriente trifásica que están concebidos para tensiones de hasta 15 kV y para corrientes de hasta 30 KA.

  • REOLAB 310

    Three-phase supply with autotransformers

    REOLAB 310
    • Corriente de salida: 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.

  • REOLAB 220

    Variable and constant high-current supply Test station for switching devices

    REOLAB 220
    • Tensión de entrada: 230/400 V / 3 x 230/400 V
    • Tensión de salida: 0...10 V / 3 x 0...10 V
    • Gama de frecuencias: 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.
