Power Amplifier

Power Amplifiers designed for APS ELECTRO-SEIS®
Long Stroke Shakers

 

The APS 125 and APS 145 DUAL-MODE Power Amplifiers are designed specifically to provide drive power for electrodynamic shakers. The amplifiers have features which make them uniquely suited for studying the dynamic characteristics of structures.

They may be operated in either a voltage or current amplifier mode, selectable from the front panel. A remote control 'Mute' input allows to remove the drive signal while the amplifier mode is retained. This feature can be used e.g. for observation of resonance decay in structures.
