INTRODUCTION
HPS is a power source that supplies a sinusoidal and stable voltage. Its output voltage is adjustable
in frequency and amplitude.
1.1.
MAIN FEATURES
1.1.1.
Output Voltage
The output voltage is guaranteed perfectly sinusoidal, with a distortion of less than 0.6%
regardless of the load. The value of output voltage is kept perfectly stable within 0.1% with linear
load and a full load.
The load that HPS is able to drive can vary from a pure capacity to a pure inductance.
The output voltage is adjustable with continuity from zero to full scale.
Furthermore, HPS is capable to keep the voltage stable with time variable loads, as for example
the pulsating loads. In fact HPS recovers the distortion of the waveform within 0.1% and the
amplitude of the voltage within 0.6% in less than half period.
HPS can in fact provide the nominal power at various full scales and this allows the HPS to adapt
himself to the disparate needs of the user, without having heavy limitations on the output current.
The HPS has only a three phase output, but It is able to supply a single phase load, in this case the
maximum power is 1/3 respect to the nominal power
Furthermore HPS is capable to keep the voltage stable also with time variable loads, as for
example the pulsating loads. In fact HPS recovers the distortion of the waveform within 0.6 % with
linear load and the amplitude of the voltage within 0.1% in less than half period.
Furthermore, HPS can bear a short circuit for an indefinite time without suffering any
consequence.
1.1.2.
Output frequency
HPS allows the regulation of the output frequency from 50 to 80Hz at maximum voltage.
This output frequency can be regulated with continuity within the above mentioned range of
frequencies and it has a stability of 0.01% with respect to the set frequency.
HPS also allows to synchronize the output frequency with the frequency of the supply line; this
synchronization is obtained both in frequency with line.
This allows a completely synchronous output, with a zero phase error regard to the supply line,
but with a completely insulated output and with a far superior voltage stability.
1.1.3.
User interface
HPS is intended to have an user friendly interface. It is also featured the possibility of an host
computer control, thus allowing to perform tests automatically. HPS allows various usage
selections: working range, wires drop compensation, working frequency, syncronization of the
output frequency with the power line. Furthermore, HPS gives the user clear information on the
status of the output. It is monitored both the set voltage and the set frequency and the output
voltage is read with a precision of 0.3%. The user is also warned in case of over current obtainable
by the HPS, or in case of high loss in the wires, that should not exceed 10% of the set voltage.
