Reactive Power Controller

Hints for installation

Mounting place

The reactive power controller Prophi is suited for mount-
ing and operation in reactive power compensation sys-
tems.
The connection is carried out on the back side via touch
proof spring power terminals.

Measurement and supply voltage

The measurement is suited for 3 phase systems with or
without neutral conductor. Measurement and supply
voltage are taken from the measurement voltage and
must be connected to the building installation via a
separation (switch or power switch) and an overcurrent
protection (2A...10A).
Attention!
m
The operating voltage for the contactors
should be taken from an outer conductor con-
nected to the reactive power controller.
The reactive power controller measures and supervises
the voltage between two outer conductors. If one of
those two fails, the reactive power controller gets no
more measurement and operating voltage, and switches
on the capacitive stages after net return according to
the programmed times.
If the third outer conductor is missing, this will not be
recognized by the reactive power controller. If the con-
tactors are supplied by this outer conductor, the contac-
tors can attract simultaneously and without considera-
tion of the discharge time after net return.
