APS 113
Ball-bearing ELECTRO-SEIS® Long-Stroke vibration exciter specifically designed to be used alone or in arrays for modal excitation of complex structures, particularly when low frequencies are required. Different operating modes with reaction masses, fixing points or auxiliary table kits multiply the application possibilities.

Performance
One application of the APS 113 ELECTRO-SEIS® shaker is to determine the dynamic characteristics of mechanical structures. At resonance, a large amount of energy is contained in the structure, and the shaker must accommodate the resulting motion. However, it need only supply the real mechanical power dissipated by damping mechanisms within the structure.

APS Reaction Mass
Reaction masses for APS exciters — compatible with models APS 113, APS 400 and APS 420 — extend performance into lower frequency ranges while allowing either horizontal or vertical force to be applied directly through the shaker body.
With an armature weight of 13.2 kg (29 lb) and a total system weight of 47 kg (103 lb), they provide the stability and inertia needed for precise, controlled excitation. Using two blocks, sufficient reaction mass is achieved to deliver the rated force down to 1.8 Hz, even in free body mode.
PA 500 DM
For all vibration exciters that require a 500 VA power amplifier (load impedance 4 Ω). The PA 500 DM offers a max. frequency range DC...200 kHz, small harmonic distortion, excellent stability even with temperature or supply line variations and helpful protection functions.
APS 0109
The APS 0109 automatically controls the zero position of a vibration exciter irrespective of its load. It is essential to employ a position controller of type APS 0109 especially when working with an air-bearing vibration shaker without any integrated automatic load-compensation.
APS Auxiliary Table Kits
Enhance your shaker system’s versatility with auxiliary mounting tables that provide a stable platform for both horizontal and vertical setups.
Designed to accommodate components, model structures, accelerometers and other low-frequency sensors, they enable precise, dependable vibration testing across a wide range of applications.
