1. INTRODUCTION
CPS/M is a power source that supplies sinusoidal stable voltage. Its output voltage is adjustable in
frequency, amplitude and phase.
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 0.1% with linear
load and a full 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.
The load that CPS/M 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.
CPS/M can in fact provide the nominal power at various full scales and this allows the CPS/M to
adapt himself to the disparate needs of the user, without having heavy limitations on the output
current.
Furthermore CPS/M is capable to keep the voltage stable also with time variable loads, as for
example the pulsating loads. In fact, CPS/M recovers the distortion of the waveform within 0.3 %
with linear load and the amplitude of the voltage within 0.1% in less than half period.
CPS/M can bear a short circuit for an indefinite time without suffering any consequence.
1.1.2 Output frequency
In AC configuration CPS/M allows the regulation of the output frequency from 10 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.
CPS/M also allows to synchronize the output frequency with the frequency of the supply line; this
synchronization is obtained both in frequency and in phase with the line.
This allows a completely synchronous output with regard to the supply line.
02/02/22 User Manual CPS/M 62000584_05 11
1.1.3 User interface
TPS is intended to have a user-friendly interface.
It is also featured the possibility of a host computer control, thus allowing to perform tests
automatically.
TPS allows various usage selections: working range, wires drop compensation, working frequency,
synchronization of the output frequency with the power line.
Furthermore, CPS/M 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 CPS/M, or in case of high loss in
the wires, that should not exceed 5% of the set voltage.

2. NOTES FOR USERS
2.1 Switching ON
As soon as CPS/M 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 CPS/M is set to 0 Volt in the range 300 Volt, 50 Hertz and regulation on the
output terminals (2 wires).
After the appearing of those indications, your CPS/M is ready to work.
2.2 PARAMETERS PROGRAMMING MODE
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
Parameters Manual, you can find it here or in the USB-Key supplied with your CPS/M.
2.3 VOLTAGE MENU
02/02/22 User Manual CPS/M 62000584_05 17
2.3.1 Setting Voltage
To set the output voltage you must use the encoder that you see on the figure, after this step the
display lamp until the output is going to the setup voltage.
2.3.2 RANGE SETTING
The CPS/M range buttons allows to make use of the full output power at different voltages.
There are two different ranges: High (300 V) and low (150 V)
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.
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
CPS/M is ready to receive on the new range.
2.4 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.
02/02/22 User Manual CPS/M 62000584_05 18
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.
02/02/22 User Manual CPS/M 62000584_05 19
2.5 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
2.6 FREQUENCY MENU
2.6.1 Frequency setting
The output frequency of CPS can be 50 or 60 hertz, the FREQUENCY display shows the set-up value
and FREQUENCY button switch the set up value.
In this case after pushing the button FREQUENCY the frequency display flashes until the output
frequency coincides with the set one.
It is possible to set the frequency between 40-80Hz only via remote control.
2.6.2 Frequency reference setting
The output frequency can have two references: the first one is a inner frequency reference with a
precision of 0.01%, the second one is the line of loading frequency.
At turn on CPS is connected to the inner reference; you can change the reference to line only with
PC remote interface.
02/02/22 User Manual CPS/M 62000584_05 20
2.7 MODE MENU
2.7.1 Voltage reaction
The stabilization of the output voltage coincides both on the CPS/M 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 CPS/M 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 CPS/M 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).
2.7.2 Output Relay
If you press the button OUT you can turn-on or turn-off the output relay. Before the turn-off the
output voltage is set to 0 voltage so the relay switch with low current. Also, the turn-on is at 0
voltage and after that, the voltage goes to the setting value with an internal ramp.
The turn off of the output relay does not allow operations on the connection of the EUT.
2.7.3 DC/AC mode
By pressing the Mode button, the CPS/M switch from AC to DC and vice versa.
