BECAUSE EXCELLENT CAPACITORS ARE NOT ENOUGH

The plug’n’play power factor controllers of our PFR-series calculate the active and reactive power in the mains from the measured
current and voltage. Their intelligent control algorithm optimizes the switching sequences and guarantees for short regulation times
with a minimum number of switching cycles. At the same time, equal distribution of switchings for capacitors of equal size extends
the lifetime of the capacitors. The integrated connection control immediately detects in which phases voltage and current are
+
measured, and adapts the entire system automatically. The very low current threshold of 15 mA (PFR-M**T) / 5mA (PFR-X **R)
allows for very reliable and exact PF control. 1A as well as 5A current transformers can be used without additional manual adjust-
+
ments. The power supply of PFR-X covers a voltage range of 90...550V, the PFR-M supply is rated for a voltage range of 207-253V or
100-132V.
The rated mains voltage is the only value to be entered before commencing operation. The controller blocks operation to protect the
capacitors if the tolerance of this voltage setting is exceeded during operation. All other relevant parameters have been preset by
the manufacturer for immediate start of operation in nearly any common configuration. Individual adjustment and optimization of the
control parameters is possible at any time, even during operation of the equipment.
Once connected, the size of capacitors or reactors is detected automatically. The lifecycles of the capacitors are determined by the
degradation of capacitance, and a pre-failure alarm can be provided.
POWER FACTOR CONTROLLERS Our controllers can monitor the temperature inside the capacitor cabinet with an integrated sensor. The temperature control can
The controllers will operate correctly even if the value of the current transformer ratio has not been entered. Please note that in

case of the PRF-X , all display functions related to current measurements will be disabled.

activate a fan connected to the related output relay (PFR-X )/the digital output (PFR-M), or switch off the capacitors if necessary.
+
External thermostats may be connected in parallel to the integrated temperature sensor (PFR-X )/to the digital input (PFR-M) to
monitor the temperature in other related cabinets.
For maintenance purposes, all capacitor outputs can be switched manually.

Display
The backlit LC-Display delivers information about the equipment and the mains conditions. Additionally, it facilitates the
input of changes during commissioning and operation.
