1. General characteristics
−
Digital power factor regulator with output relays for the connection and the
disconnection of capacitive banks.
−
Designed to obtain an optimal power factor in the plant and an equal wear of both the
capacitors and the switching contactors.
−
Microprocessor control circuit with high performances.
Accurate measuring system also in presence of harmonics.
−
Easy installation.
−
Easy setting and monitoring through the keyboard on board.
−
Dual auxiliary voltage supply 110-127/220-240VAC.
−
Measuring voltage input: any voltage from 80 to 500VAC.
−
Measuring current input: any standard C.T. with secondary 5A (1A on request).
−
Current measurement in true RMS, also in presence of harmonics.
−
Automatic intelligent regulation.
−
Adjustable sensitivity (time integral).
−
Same step reconnection delay (adjustable).
−
Equal use of the steps (automatic registering of the switching operations and the
working time of each step).
−
Line monitoring: cower factor, current, frequency.
