The LIAM 6005 Linear Power Supply main block diagram, with its principal
features, is hereafter presented in
Figure 3
.
The proposed control scheme is a well-known topology that guarantees high
stability and high reliability for the entire system.
The three-phase transformers convert the mains input power, rated at 200VAC
and 50-60 Hz, to different DC voltages: +V
DD
, -V
DD
and ±V
AUX
and they act as the
main AC/DC section
Please note that, for safety and protection issues, all input phases are protected
with circuit breakers (
carefully read Installation section in order to safely and
correctly install LiAM 6005 power units
).
The V
AUX
voltages are used to power up the control electronic sections of the
power supply and are obtained from different windings with respect to the power
voltages.
The digital control section of the LIAM 6005 takes care of the general power
supply diagnostics, the interfacing to the Ethernet communication module, the control
of the DAC, the display handling and some other tasks.
Module can perform waveforms as sine or square waves (or any other user-
defined waveform) controlling the LIAM 6005 via Ethernet connection; this can
easily be performed by transmitting to the power supply the desired waveform on a
point-by-point basis (the maximum data-rate frequency for the set-points is more than
100Hz).
