    amplifier
    general introduction
    using the mosfet field-effect’s high frequency switch power, through digital circuit to amplify and restore the low-voltage signal which input by controller, then the output the original signal to vibration tester's moving coil circuit, and drive vibration tester's extension table movement.
    functional features
    this system adopts the sine pulse width modulation technology of digital power amplifier. its working principle is: protection function: the power amplifier set up protection of power grid over-voltage, power grid under-voltage, power grid lack of phase, logic fault, power module, power temperature module, output over-current, output over-voltage, driving power, the table’s displacement, table temperature, etc. any failure occurs, shut down output, with sound and lighting alarm at the same time. except the above protection, also has poor rms value the protection, and emergency stop protection.
    high conversion efficiency ( higher than 92%), and high conversion frequency .
