INTRODUCTION
RPS/T is a power source that supplies sinusoidal stable voltage. Its output voltage is adjustable in
frequency and amplitude.
RPS/T has an isolated output thanks to a special isolating transformer at constant power. This
transformer allows to have always the maximum power in any application, keeping the complete
insulation from the electrical line. (the transformer is not supplied with the RPS/T)
RPS/T has to be controlled remotely.

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 % f.s. regardless of the load.
RPS/T is also able to compensate for possible voltage drops on the output wires, ensuring the
exact amount of voltage you want on the load.
The load that RPS/T is able to drive can vary from the pure capacity to the pure inductance; not
only, but also up to non-symmetrical current loads, as for instance a single halfwave rectifier.
The output voltage is adjustable with continuity from zero to full scale of each range.
RPS/T can in fact provide the nominal power at various full scales and this allows the RPS/T to
adapt himself to the disparate needs of the user, without having heavy limitations on the output
current.
Furthermore RPS/T is capable to keep the voltage stable also with time variable loads, as for
example the pulsating loads.
In fact RPS/T recovers the distortion of the waveform within 0.6 % and the amplitude of the
voltage within 0.3% in less than half period.
RPS/T can bear a shortcircuit for an indefinite time without suffering any consequence.
1.1.2.
Output frequency
RPS/T allows the regulation of the output frequency from 40Hz to 80Hz.
This output frequency can be regulated with continuity within the above-mentioned range of
frequencies and it has a stability of 0.01% with regards to the set frequency.
RPS/T 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 isofrequency output, with regard to the supply line, but with a completely insulated
output and with a far superior voltage stability.
It must be remarked that, in three phase version, trough remote interface, it is possible to set a
variable phase delay on all the three outputs, this is useful for example, to study single phase
