Although the input voltage range is ±15 % for the standard models, under request, it is possible to
manufacture equipment’s with wide input voltage range up to ±30 % (input voltage window).
The voltage stabilizer protects against sudden changes, irregularities, increasing or decreasing of the voltage
mains by means of an accurate voltage stabilization.
Also, as standard the control electronic unit includes the Maximum and minimum voltage protection signal
(adjustable to input or output, but by default on the last), which is needed to disconnect the output by means
of a contactor. In case of the voltage exceeds the allowed limits or mains fault. In order to keep the protection
against sudden voltage changes, the signal is delayed a few seconds.
It is also possible to include an option that allows disconnecting the output of the stabilizer due to overload.
In this case, the equipment will include the output current sensors to make the overload measurement.
As an option, the stabilizer can be equipped with a manual Bypass, which is not ready to be maneuvered
with load connected. It allows keeping the loads supplied during the maintenances or fixing periods.
