Power amplifier for vibration exciters Spektra PA 800 DM

Specification PA 800 DM

The SPEKTRA Power Amplifier PA 800 DM has been developed to drive any type of exciter requiring a 810 VA power amplifier with a load impedance of 2.5 Ω. It has a useable frequency range from 20 Hz to15 kHz at full power or from DC to 25 kHz small signal; the harmonic distortion is very small. The power amplifier can tolerate temperature and supply line variations while maintaining excellent stability.

Thereby, the product can be used as a voltage generator with low output impedance and a flat voltage frequency response, or as a current generator with high output impedance and a flat current frequency response. The maximum RMS output-current limit is adjustable. For standard applications, we recommend using the product in voltage mode.
