AMPLIFIERS

a649hv.gif (5790 octets)

During structural analysis, force control is critical.
The forces must be independent of the motions.
PRODERA's current controlled amplifiers solve
this problem.

Specially developed for the PRODERA's modal
electrodynamic shakers, our power amplifiers were
designed for optimum results during modal analysis.

UNIQUE FEATURES

  • From 30 to 4000 Watts
  • Accurately controlled output current
  • High output impedance does not impede motion
  • Constant force of shaker independent of motion
  • Display of the position of the moving assembly (as from the model A 648 S/SM)
  • Remote controlled (as from the model A 648)
  • Accurate measurement of introduced force Newton / Volt therefore no need for force transducer

VIBRATION SHAKERS
Your Vibration Solution

ex520c50.jpg (18050 octets)














During structural analysis, forces are imposed on
the structure, and the resulting movement function
gives us the structure's mathematical model.

As it is the basis for all the analysis, modal shakers
must be able to provide the requested force for an
adapted frequency range, without disturbing the
characteristics of the structure under test.

PRODERA modal electrodynamic shakers are based
on the Laplace Law. A coil is situated inside the thin
air gap of a magnetic field, providing a sine, random
or shock force.

EX 520 C 50 Long stroke shaker

UNIQUE FEATURES

  • Current controlled shakers
    • Nominal forces from 3 to 5 000 N (0.67 to 1124 lbf)
    • Light, linear and robust moving assembly
    • Low stiffness
    • Display of the position of the moving system
          (as from the EX 220 SC type)
