The Computer SMART III is a reactive energy regulator. The device measures the cos φ of the mains
Power Power
and regulates the connection and disconnection of capacitors, via the relays, in order to correct it.
The control is carried out at the four quadrants, .

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