SPA-K amplifiers are intended for use in combination with LDS air-cooled vibration test systems from the V830 to the V8 and are designed with a built-in field power in addition to the blower power supplies. They are equipped with a micro-processor control unit and LCD function display and feature the Amplifier Controller Software that enables remote operation of both the power amplifier and vibration controller from the same PC, or other vibration test equipment. They are capable of peak current rating of 3-sigma that complies to ISO standards and very low harmonic distortion of less than 0.15% at full power, while the variable field control provides optimal power usage and harmonic distortion.
