3�- PRODUCT DESCRIPTION
The power factor regulators, of types computer MAX 6 and MAX 12 measure the cos φ (some -
times called Displacement Power Factor, DPF) in a supply network and control the connection
and disconnection of power capacitors in order to regulate such parameter.
The difference between the two types is the number of output relays, which determines the
number of stages that they can control.

Model Maximum Nr of output relays
computer MAX 6 6 relay outputs
computer MAX 12 12 relay outputs
Among the most important features of this PF regulator series we can stand out the following:
-
FCP regulation system,
which minimizes the number of switching operations.
- Wide choice of switching programs : 1:1:1, 1:2:2, 1:2:4 , 1:1:2:2, etc. which allows the
split up of the total power into up to 31 steps in MAX 6 or up to 79 steps in MAX 12 .
-
Four quadrants control
(see
Figure 2
), display of the connected stages, of cos φ and
active and reactive power signs (inductive or capacitive ).
- LCD display screen with three seven segments characters plus 20 icons to sign up the
different possible working conditions.
- Regulator set-up with only three keys and without disconnecting the device from the
supply.
- Multiple supply frequency range, either 50 or 60 Hz
- Main electrical parameters displayed during RUN mode
- Easy panel mounting, without the need of tools.
- Front frame size (144 x 144 mm) according to DIN 43 700 (panel hole 138
+1
x 138
+1
mm)
- Measurement and power supply in one single input.
- Four quadrant regulation (suitable for installations importing or exporting energy)
