POWER FACTOR REGULATOR Controller
The Controller
/
PF regulators measure cosϕ in a supply system and control the connection and disconnection of capacitors to
obtain a target programmed value.
This manual is an easy guide for the use and operation of the
Controller
/
. For more information, the complete
manual can be downloaded from the web site of ZEZ SILKO

Any manipulation or use of the equipment out of the conditions
specified by the manufacturer may put in risk the user safety. Before
any maintenance operation the equipment must be disconnected from power
supply. In case of miss operation or protection fault the equipment must be
disconnected from supply and remain out of service ensuring against any
accidental reconnection.
1.- Regulator Connection
For proper operation it’s necessary to install a current transformer, CT
(normally In / 5 A), which primary must be sized according to the
maximum expected load current in the installation.
The regulator supply (C-D terminals) must
phases and the CT should be located in the third phase. See technical
characteristics for cable sizes and required protections.
Must use an switch or automatic switch for supply the regulator
The current
transformer , CT,
must be located so that it
measures the whole load current
plus the correction capacitors

3.- Four Quadrants Operation
The Controller
/
regulators operate in 4 quadrants (suitable
for imported or exported active power). For exported power, a negative
symbol is displayed in the cosϕ indication. Check phase connection and
setup if there is no exported energy and the indication is not correct (see 4.3,
SET-UP - phase)
