    When it is enabled, the power supply goes on stand-by mode that displayed on LCD
  • Short Circuit Protection
    In all frequencies, the output is electrically protected from short circuits either with “DC” programming output or with “AC” programming output
     

    TECHNICAL FEATURES AC OUTPUT

    Output Frequency
    The power supply is provided of 3 internally generated frequencies of 50 – 60 – 400 Hz selectable through a push button and adjustable in ± 5% for the frequency limit reachable through a multi-turn trimmer that is located under the push button of selection. The power supply in amplifier mode can work with sinusoidal frequency up to 10 kHz to carry out arbitrary voltage profiles through the reaction time to remote programming, better than 8 V/µs
    Frequency stability
    better than ± 0,1%
    Frequency distortion
    Measured in voltage mode and in all frequencies (up to 10 kHz) better than 0,5 %
     

    TECHNICAL FEATURES DC OUTPUT

    Reaction to remote programming
    better than 8 V/µs
    Recovery time
    better than 200 ms within ± 0,2% of set voltage from no load to full load
    Ripple and noise
    measured in V mode, better than 0,02% of the voltage rated
