Introduction:
VArKON series reactive power controllers have been developed to
solve the power factor correction problems by suitable models for
different kind of power systems.
That controller can be started up and easy commissioning on any
kind of power factor compensation system for controlling and energy
analysis with their reach and real user friendly menu.
When first starting up the compensation system with VArKON
controllers;
- It is very easy to define the stage power according power
analysis on the system’s reactive power requirements and
gives some suggestions with reactive and active power rates.
Thus shows; necessary capacitive and/or inductive reactive
powers to connect for several steps as guidance.
- Corrects the connection errors, learns and detects
continuously the step powers, records the important events
on real time.
- Works smartly leading and lagging side in order to reach to
the requested target in intelligent timing, thus lets the
minimizing the operations and maximizing the life of the
system.
- All models meet the capacitors and reactors, but model TCR
makes inductive adjustments sensitively and let the single
phase requirements to be minimized.
The controllers which can be used
successfully with the contactors are
suitable some facilities as below:
Industrial facilities with 3-phase
Factory plants
Petrol stations
Markets
Banks
Schools
Buildings
Housing estate
Official plants
Hotels
The controllers which can be used
successfully with the thyristors, hybrits
and TCRs are suitable some facilities as
below:
Welding shops

Connection Diagramme:
Most necessary information on the
main display
-Monthly-weekly-daily-hourly rates
-Real-time clock
-Reach analyzing parameters
-Sensitive measuring as 5mA
-Measuring up to 63th harmonics
-Accuracy as 0.2%
What is the suggests about daily
requirements on the steps?
No need further power analyzing!
For example according display as above:
At first line – If you add 5kVAr 3ph unit
Inductive rate will be reduced 6.2%.
At fourth line – If you connect; 1kVAr
reactor to L3 phase, capacitive rate will
be reduced 0.7%
What is the position of the steps?
You can switching cycles and connection
time for all of the steps in one display.

Communication:
VArKON power factor controllers are equipped with
a RS485 communication port as optional or
standard. The Modbus RTU protocols are available
through the RS485 in order to interconnect the
VArKON or PLC systems. All parameters can be
followed or relay adjustments and/or commands
could be set/reset.
Easy to reach for all parameters and set/reset possibility by means of internet connection with free VArKON NET and VArKON COM soft
