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.
