ANP 5kVA
printNumerical power amplifier

amplificateurThe ANP 5kVA numerical power amplifier is a numerical / analogical power converter which functions in horizontal splitting. It is made of modular power levels which each have each their own isolated power supply, switching, and for which the exits are directly coupled in series.

Advantages

  • Each form of a wave is amplified, even at average non nil value
  • Runs using a very large frequency band (from 0 Hz up to 20 kHz) and independent from the phase difference of the charge
  • 4 quadrant running

Applications

We can find :

  • Low frequency and very low frequency piezoelectric power source for transducers, either in linear mode (SONAR antenna transmission) or acoustic cavitation mode (ultrasonic cleaning, dust removal, lamination, industrial process of vibration generation
  • Power source for electrodynamical  transducers which are operational at very low frequencies (some Hz)
  • Power source for magnetostrictive transducers (alternative signal + continuous polarization component
