The a.c./d.c. rectifiers of this series, are products specially designed to feed d.c. current critical loads that require high reliability .

Associated with the suitable batteries they make up a high reliability d.c uninterruptible supply system.

Its advantages compared to the standard rectifiers are:

-They admit a.c. single phase voltage feeding (from the overhead power cable) or three phase voltage ( from generator ) and, in this case, the currents absorbed are equilibrated.

-They are insensible to any voltage and frequency perturbation, or a.c. voltage distortion, and to all of them simultaneously.

-They present extraordinary dynamic regulation in case of grid voltage and load variations, with response times of 5 milliseconds

-They do not absorb reactive energy, presenting displacement factors higher than 0,95.
