1. INTRODUCTION
TPS/T is a power source that supplies sinusoidal stable voltage. Its output voltage is adjustable in
frequency and amplitude.
TPS/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.
TPS/T can also be controlled remotely.
1.1. MAIN FEATURES
1.1.1. Output voltage
The output voltage is guaranteed perfectly sinusoidal, with a distortion of less than 0.3 %
regardless of the load.
The value of output voltage is kept perfectly stable within 0.3 % regardless of the load.
It’s designed for harmonics and flicker test. It meets the corresponding specifications as per EN
61000-3-2 and EN 61000-3-3.
TPS/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 TPS/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.
TPS/T can in fact provide the nominal power at various full scales and this allows the TPS/T to
adapt himself to the disparate needs of the user, without having heavy limitations on the output
current.
Furthermore TPS/T is capable to keep the voltage stable also with time variable loads, as for
example the pulsating loads.
In fact TPS/T recovers the distortion of the waveform within 0.3 % and the amplitude of the
voltage within 0.3% in less than half period.
TPS/T can bear a shortcircuit for an indefinite time without suffering any consequence.
1.1.2. Output frequency
TPS/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.

27/01/22 User Manual TPS/T 10-90kVA 62000560_09_ 11
TPS/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 a completely syncronous output, with a zero-phase error 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
motor with starting capacitor, or in all those cases where a different phase displacement than
three phase is required.
The resolution of phase setting is 0,088° (12 bits on 360°).
1.1.3. User interface
TPS/T 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.
TPS/T allows various usage selections: working range, wires drop compensation, working
frequency, synchronization of the output frequency with the power line.
TPS/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 0.3%.
The user is also warned in case of overcurrent obtainable by the TPS/T, or in case of high loss in
the wires, that should not exceed 5% of the set voltage.
We underline again that TPS/T automatically limits the maximum allowed current, avoiding
damages to the equipment; in 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 TPS/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 TPS/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 TPS/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 TPS/T is ready to work.
3.2. PARAMETERS PROGRAMMING MODE
TPS/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

3.3.1. 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.
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.
3.4. RANGE SETTING

27/01/22 User Manual TPS/T 10-90kVA 62000560_09_ 19
The TPS/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.
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
TPS/T is ready to receive on the new range.
3.5. 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.
3.6. FREQUENCY MENU
3.6.1. Frequency setting
The output frequency of TPS/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 TPS/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.
3.6.2. 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.
