1 COMPUTER PLUS TF POWER FACTOR REGULATORS
The regulators in the Computer plus series are power factor regulators that incorporate the latest advances
in technology regarding power factor compensation and harmonic filtering, both in systems with contacts and
in fast systems. The core of the controller is a state-of-the-art DSP processor that allows the quick and
efficient execution of advanced control algorithms.
The Computer plus TF regulators described in this manual are static switching regulators to be used with
contactor-driven capacitor banks. For information about the Computer plus T8 and T14 types for
contactors, see manual M98223001-01-AAx. (AAx: AA are the last two digits of the year of revision and x is
an alphabetical character, A…Z, used to indicate the version).
