1. INTRODUCTION
HPS/T is a power source that supplies sinusoidal stable voltage. Its output voltage is adjustable in
frequency and amplitude.
HPS/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.
HPS/T can also be controlled remotely.
One of the HPS/T peculiarity is the 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.
1.1. MAIN FEATURES
1.1.1. Output voltage
The output voltage is guaranteed perfectly sinusoidal, with a distortion of less than 0.6 % with
resistive load.
The value of output voltage is kept perfectly stable within 0.1 % regardless of the load.
HPS/T is also able to compensate possible voltage drops on the output wires, ensuring in this way
the exact voltage you want on the load.
The load that HPS/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 half wave rectifier.
The output voltage is adjustable with continuity from zero to full scale of each range.
HPS/T can in fact provide the nominal power at various full scales and this allows the HPS/T to
adapt himself to the disparate needs of the user, without having heavy limitations on the output
current.
The HPS/T has only a balanced three phase output, but it’s able to supply a single-phase load, in
this case the maximum power is 1/3 respect to the nominal power
Furthermore, HPS/T is capable to keep the voltage stable also with time variable loads, as for
example the pulsating loads. In fact, HPS/T recovers the distortion of the waveform within 0.6 %
and the amplitude of the voltage within 0.1% in less than half period.
HPS/T can bear a shortcircuit for an indefinite time without suffering any consequence.

02/02/22 User Manual HPS/T 62000590_07_ 11
1.1.2. Output frequency
HPS/T 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/T also allows to synchronize the output frequency with the frequency of the supply line; this
synchronization is obtained both in frequency and phase.
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/T is intended to have an user friendly interface.
It is also featured the possibility of a host computer control, thus allowing to perform tests
automatically.
HPS/T allows various usage selections: working range, wires drop compensation, working
frequency, syncronization of the output frequency with the power line.
Furthermore, HPS/T 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 0.6%.
The user is also warned in case of over current obtainable by the HPS/T, or in case of high loss in
the wires, that should not exceed 5% of the set voltage.
We underline again that HPS/T automatically limits the maximum allowed current, avoiding
damages to the equipment; the only consequence is that, in this case, it is not guaranteed the
precision of the output waveform neither the accuracy of the output voltage.
The user can set the output voltage through the numeric keyboard, or he can continuously vary
the voltage through specific keys. The same possibility is valid for the setting of the frequency.
The above possibility makes the HPS/T very flexible in those applications where it is requested a
continuous variation of the two regulated magnitudes, around a given values.

3. NOTES FOR USERS
3.1. SWITCHING ON
As soon as HPS/T switches on, through the switch placed on the control panel of the machine, it
makes different cycles of test, indicated by the progression of the numbers from 0 to 9 on the
displays.
In case of bad working the test stops and the machine indicates on the control panel the type of
alarm checked (see at the voice alarms).
When the test ends HPS/T is set to 0 Volt in the range 300 Volt, 50 Hertz and regulation on the
output terminals (2 wires).
After the appearing of these indications HPS/T is ready to work.
3.2. PARAMETERS PROGRAMMING MODE
HPS/T allows you to change various generator start parameters through the programming mode.
The programming mode allows you to configure a starting profile of the application, different from
the factory one.
The modifiable parameters and how to access the programming mode are illustrated in the
Configure parameters quick guide.
3.1. VOLTAGE MENU
3.1.1. Setting Voltage
There are two ways to set the Voltage: through the appropriate buttons UP and DOWN placed on
the left on the control panel or through the numeric keyboard.

02/02/22 User Manual HPS/T 62000590_07_ 17
The buttons UP and DOWN, respectively indicated with a little arrow upwards and downwards,
permit a continuous variation of the output voltage; the speed of the output voltage variation
depends on time the button is pushed, as time increases, the speed of the output voltage variation
progressively increases.
Instead, if you want to set a fixed output voltage, you can use the numeric keyboard situated on
the right side of the control panel.
To set a fixed output voltage proceed in the following way:
1. Push the button PROGRAM (the corresponding led switches on)
2. Push the button VOLT (the volt display switches off)
3. Digit the required voltage through the numeric keyboard (the numbers are visualized on
the display)
4. Push ENTER.
After pushing ENTER the display begins to blink, this is to indicate the output is going to the set
voltage, as soon as the connection takes place, the display stops to flash and the PROGRAM led
shuts off.
In case of error, you can push the button CLEAR which causes the exit from the programming
routine.
The maximum voltage is equal to the set off range.
Moreover, if the set off voltage is not coherent with the set off range (for example the setting of a
voltage exceeding the range) the datum is not accepted after pushing ENTER.
3.2. RANGE SETTING
The HPS/T range buttons allows to make use of the full output power at different voltages.
There are two different ranges: 300 Volt and 150 Volt.

02/02/22 User Manual HPS/T 62000590_07_ 18
The maximum output power changes according to the nature of the connected load; in case of
resistance loads the power is nominal, in case of pure inductive loads the power increases, in
case of pure capacity load the power diminishes.
To change the range, push the button corresponding to the requested range placed on the left
of the command panel under the voice RANGE VOLT.
When the range is changed, the display showing the set voltage turns off and the output voltage
goes down slowly till zero, then the output power is switched off; after about 15 seconds the
output is switched on again and the Volts display visualizes zero voltage (0.0); since that moment
HPS/T is ready to receive on the new range.
3.3. VOLTAGE VISUALIZATION
The display concerning the output voltage can visualize the set voltage or the output voltage with
four digits both.
At turn on, the display visualizes the set voltage and this is indicated by the led on the button SET
in the DISPLAY VOLT section of the panel.
In order to visualize the actual output voltage, push the corresponding button (OUT); the
visualized voltage indicates the output voltage with a precision of 0.3% at full scale range.
If the set voltage is changed, the display returns to show the set value.
In case of 4 wires operation, the display shows the voltage on the sense inputs.

3.4. FREQUENCY MENU
3.4.1. Frequency setting
The output frequency of HPS/T can change between 40 and 80 hertz.
To set the frequency proceed likewise the setting voltage through the buttons UP and DOWN
(upwards and downwards arrow) and by means of the programming numeric keyboard.
To set the frequency through the programming numeric keyboard you can proceed likewise the
voltage pushing the button HERTZ instead of the button VOLT thus indicating to HPS/T that you
want to program the frequency.
Either in this case after pushing the button ENTER the display concerning the Hertz value
visualization flashes until the output frequency coincides with the set one.
If you plan a frequency exceeding the frequency range, the input value is not accepted pushing the
button ENTER.
3.4.2. Frequency reference setting
The output frequency can have two references: the first one is an inner frequency reference with a
precision of 0.01%, the second one is the line of loading frequency.
At turn on HPS/T is connected to the inner reference and this state is signalled by the led
corresponding to the button INT at the voice FREQ. REF.
To connect the output frequency to the network frequency, push the button LINE; in this case the
output frequency is brought at 50 Hertz (this is indicated by the flashing of the visualized
frequency); when the connections with the 50 Hertz takes place, HPS/T is connected to the
network frequency and the display concerning the frequency switches off.

The state of connections to the network is indicated by the led corresponding to the button LINE.
HPS/T connects itself to the medium frequency of the network (with a period of integration equal
to about 30 seconds) to eliminate probable line voltage failures or spurious impulses arranged on
the same line.
To return to the inner frequency reference push the button INT, after about 10 seconds the
display will visualize 50.00 and the output frequency will be connected to the inner reference.
3.5. MODE MENU
3.5.1. Voltage reaction
The stabilization of the output voltage coincides both on the HPS/T output terminals (2-wires) and
on a possible long distance outlet (4-wires) to eliminate the fall in voltage influence of the
connections.
To operate the long-distance stabilization first connect the SENSE terminals on the back of the
machine following the indications at the voice INSTALLATION.
The choice of the kind of long-distance stabilization can be operated by means of the buttons 4
wires and 2 wires at the voice SENSE.
Notice that HPS/T corrects falls in voltage on the connections until 5% of the set-up voltage to
avoid possible overheating of the line; after exceeding this limit HPS/T doesn’t guarantee that the
value of the output voltage is equal to the set-up voltage and an error signal appears (see at
voltage alarms).
