Computer SMART III FAST 12Vdc
4.- OPERATION
The Computer SMART III FAST 12Vdc is a reactive energy regulator unit that measures the cos φ of the
grid and that regulates the connection and disconnection of capacitors in order to correct it.
The control is carried out in the four quadrants, Figure 11 .

In addition to the basic functions of any regulator the Computer SMART III FAST 12Vdc:
 Performs the functions of a network analyzer, measuring and displaying multiple parameters.
 Has a Plug&Play function for automatic configuration of the unit.
 Has an AutoTest and manual Test function for testing the status of the capacitor bank capacitors.
 Has an FCP system which minimises the number of capacitor connections and disconnections.
 Supports step forcing.
 Can work with various connection types.
 Measures leakage current with the option of associating an alarm and conducting a search for and
cancelling the faulty capacitor.
 Has multiple alarms for warning of possible faults, whether in the capacitor bank or in the installa-
tion.
