Reactive Power Controller

Product description

Intended use

The reactive power controller Prophi together with ex-
ternal capacitor stages, serves for step by step control-
ling of the phase shift angle cos(phi) in 50/60Hz low
voltage networks. Depending on the type of the reac-
tive power controllers Prophi, contactors or semi con-
ductor switches can be controlled directly.
Additionally, the following electrical quantities are meas-
ured and indicated:
- Voltage L2-L3,
- Current in L1,
- Frequency,
- Sum real power (Consumption/supply),
- Sum reactive power (ind./cap.),
- uneven current harmonic waves 1. - 19. in %,
- uneven voltage harmonic waves 1. - 19. in %.
The harmonic contents are related to the rated voltage
or rated current.
The connection is carried out on the back side via touch
proof spring power terminals.
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 (6,3A).
The current measurement is carried out via a ../5A or
../1A current transformer in one outer conductor.
The relay outputs are suitable for contactor control, the
transistor outputs are provided for the control of fast
switching thyristor modules, switching at zero crossing.

Hints for maintenance

Before delivery the device is tested in various safety
checks and marked with a seal. If the device is opened,
these checks must be repeated.
There is no guarantee for devices, which are opened
out of the manufacturing works.

Repairing and calibration

Repairing and calibration work can be carried out in the
manufacturing works only.

Front foil

The cleaning of the front foil must be done with a soft
cloth using a common cleansing agent. Acid or acidic
agents may not be used for cleaning.

Waste management

The device can be disposed as electronical waste ac-
cording to the legal regulations and recycled.

Data protection

The data protection is carried out in a none volatile
memory (EEPROM).
Changed programming data are saved immediately.
