USER MANUAL TPS/M 62000595 REV 03_ – 01/06/2021
1.1.3. User interface
TPS 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 allows various usage
selections: wires drop compensation, working frequency. Furthermore, TPS gives the user clear
information on the status of the output. Set voltage and set frequency are monitored and the
output voltage is read with a precision of 0.3%.
The user is also warned in case of over current obtainable by the TPS, or in case of high loss in the
wires, that should not exceed 5% of the set voltage.
We underline again that TPS 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 LCD touchscreen, the same possibility is valid for
the setting of the frequency and the phase.
The above possibility makes the TPS very flexible in those applications where it is requested a
continuous variation of the two regulated magnitudes, around a given values.
1.1.4. General performances
All the following features are valid within the range of the normal operating limits; they are not
valid during the limitation of the output current
(1)
With linear load.
1.1.5. General specifications
The voltage is referred phase to neutral, with neutral connected to the earth.
PARAMETER VALUE
Output Frequency Range DC or 10Hz - 80Hz
(1)
Phase Resolution 1°
Frequency Resolution 0.02Hz
Frequency Precision and Time Stability 100ppm
Output Voltage
(2)
300Vac - 300Vdc
Output Voltage Resolution 0.025% f.s. (12 bit f.s.)
Operating Temperature 0°C - 35°C
(1)
Frequency can be increased up to 320 Hz at lower performance than the nominal.
(2)
The RPS works at constant output current so if you decrease the voltage you decrease also the
maximum power.
PARAMETER VALUE

(1)
<0.3%
Stability of the output voltage <0.1%
Accuracy of the output voltage <0.5%
Recovery-time of the output waveform <200us
Maximum compensated drop on wires 5% f.s.
Recovery time of RMS <200ms
