1. INTRODUCTION
CPS/T is a power source that supplies sinusoidal stable voltage. Its output voltage is adjustable in
frequency and amplitude.
CPS/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 less than 0.6 % regardless
of the load. The output voltage value is kept perfectly stable within 0.1 % regardless of the load.
CPS/T is also able to compensate for possible voltage drops on the output wires, ensuring in this
way the exact voltage you want on the load.
The load that CPS/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.
CPS/T can in fact provide the nominal power at various full scales and this allows the CPS/T to
adapt himself to the disparate needs of the user, without having heavy limitations on the output
current.
Furthermore, CPS/T is capable to keep the voltage stable also with time-dependent loads, as for
example the pulsating loads. Indeed, CPS/T recovers the distortion of the waveform within 0.6 %
and the amplitude of the voltage within 0.1% in less than half period.
Furthermore, CPS/T can bear a short-circuit for an indefinite time without suffering any
consequence

1.1.2 Output frequency
CPS/T allows the regulation of the output frequency from 50Hz or 60Hz by panel and 10-80Hz by
remote control.
This output frequency can be regulated with continuity within the above frequency’s range and it
has a stability of 0.01% with regards to the set frequency.
CPS/T also allows to synchronize the output frequency with the frequency of the supply line (from
remote control). This allows a completely synchronous voltage output, with a far superior voltage
stability.
It must be remarked that, through remote interface, it is possible to set a variable phase delay on
all the three outputs.
The resolution of phase setting is 0,088° (12 bits on 360°).
1.1.3 User interface
CPS/T is designed to have a user-friendly interface.
It is also featured the possibility of a host computer control, thus allowing to perform tests
automatically.
CPS/T allows various usage selections: working range, wires drop compensation, working
frequency,
synchronization of the output frequency with the power line.
Furthermore, CPS/T gives the user clear information on the status of the output.
It is monitored both the set voltage, the set frequency and the output voltage and current is read
with a precision of 0.3%.
The user is also warned in case of overcurrent obtainable by the CPS/T, or in case of high loss in
the wires. this should not exceed 5% of the set voltage.
We underline again that CPS/T automatically limits the maximum allowed current, avoiding
damages to the equipment.
When it occurs, the precision of the output waveform and the accuracy of the output voltage are
not guaranteed.
The user can set the output voltage through the knob, for the frequency you can choose
50Hz/60Hz.

3. NOTES FOR USERS
3.1 SWITCHING ON
As soon as CPS/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).
Caution: The front switch is not a security switch, it opens only the three phase power line also
the neutral is connected. High dangerous voltage remains inside the machine.
3.2 PARAMETERS PROGRAMMING MODE
CPS / 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.
3.3 VOLTAGE MENU
To set the output voltage you must use the encoder that you see on the figure, after this step the
set of voltage the display lamp until the output is going to the voltage set up.

28/01/22 User Manual CPS/T 5-40k 62000585_03_ 18
3.4 RANGE SETTINGS
The ranges button allows to make use of the full power output at different voltages, 150V (Low)
or 300V (High).
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 decreases. To change the range, push the button RANGE
highlighted in the figure.
When the range is changed, the voltage display 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 voltage display visualizes zero voltage (0.0); since that moment CPS/T is ready to
receive commands on the new range
3.5 CURRENT AND VOLTAGE VISUALIZIATION
When CPS/T is turned on for the first time, the display visualizes the set voltage. In order to
visualize the actual output voltage, push VOLT button and the SELECT button to choose the line.
The displayed voltage value has a precision of 0.3% 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.
You can see the output current on CURRENT display.

28/01/22 User Manual CPS/T 5-40k 62000585_03_ 19
There are two different selection buttons, the one below the voltage display changes the
displayed line for the voltage and the one below the current display changes the displayed line for
the current.
Both current and voltage displays show four digits
3.6 FREQUENCY MENU
3.6.1 Frequency setting
The output frequency of CPS/T can be set at 50Hz or 60Hz, the FREQUENCY display shows the set
up value and FREQUENCY button switch the set up value.
In this case too after pushing the button FREQUENCY the frequency display flashes until the
output frequency coincides with the set one.
3.6.2 Frequency reference setting
The output frequency can have two different 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 CPS/T is connected to the inner reference; you can change the reference to line only
with PC remote interface.

3.7 CONTINUOUS AND INRUSH MODE
Through the current key you can select the Continuous (Amp) or inrush (Amp%) configurations, it
changes the limit of peak and RMS current. The change is available of until the machine is running
3.8 MODE MENU
3.8.1 Voltage reaction
The output voltage’s stabilization behaves in the same way in both the CPS/T output terminals (2
WIRE) and on a possible long-distance outlet (4 WIRE), to eliminate the fall in voltage due to cable
connections.
To operate the long-distance stabilization, first connect the opposite terminals on the back of the
machine following the indications at the voice INSTALLATION.
The output voltage’s stabilization can be chosen by pushing the buttons SENSE, the 4WIRE and
2WIRE configuration is indicated with a LED.
