General Description - Ducati Energia REGO 5 Manuel D'instruction

3) GENERAL DESCRIPTION

The REGO reactive power controller is designed to control and regulate
capacitor banks. It operates on the basis of microprocessor technology,
which provides accurate, reliable power factor measurements.
The power factor is controlled by switching capacitor banks according
to the reactive power requirements of the load: if more than one step
is needed in order to reach the cosϕ required, REGO activates all the
steps necessary with a delay between one and the other equal to the
set time "T2". The number of switching operations is thereby reduced
and where the capacitor banks have an equal value, they will be used
in a homogeneous manner.
The controller features both automatic and manual operating modes.
In addition, the powers associated with the steps can be automatically
acquired thanks to the "AutoAcquisition" function. At the end of this
procedure, moreover, the controller also automatically selects the most
appropriate switching sequence. Alternatively a user program, chosen
among the numerous available options, can be manually set. Thanks
to this function the controller will be able to intervene and correct the
system PF more quickly: in fact, on the basis of real-time power
measurements and the known powers associated with individual steps,
it can calculate how much reactive power is needed to bring the cosϕ
to the desired value and switch on all the necessary steps together
(with just a settable delay "T2" between one and the next), as noted
previously.
The 7- or 12-step model also features an Rs485 serial interface with
standard "DUCATI" communication protocol which enables the user to
connect the device to a network of instruments and read the measured
data remotely from a connected PC.
