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
