Performance

The possible performance charts for vibration measurements with different payloads are exemplified in the following diagram. Those performance charts are based on operation of the SE-14 with its recommended power amplifier APS 145.

Acceleration with various payloads

PA 800 DM

PA 800 DM

810 VA power amplifier

For all vibration exciters that require a 810 VA power amplifier (load impedance 2.5 Ω). The PA 800 DM offers a max. frequency range DC…25 kHz, small harmonic distortion, excellent stability even with temperature or supply line variations and helpful protection functions.
