Important notes at the end of this document.

Controlling

 Simple controlling 3-phase (3-phase capacitors), max. 15 switching outputs. For 3-phase-

measurement: controlling is done either according to the worst cos φ or average value. For single-

phase-measurement: 2 current inputs are additionally available for measured capacitor bank

currents

 Single phase controlling: max. 5 switching outputs for each phase (3 · 5 switching outputs); each

phase is controlled separately. Single phase capacitors are switched to neutral.

 Mixed controlling: e.g. 3 · 3 single phase capacitors per phase (L-N) for balancing and additional 6

outputs for normal 3-phase-capacitors.

 Separate controlling of single phase capacitors L-L (without neutral)

Error messages

 Over voltage/under voltage/no voltage

 Over current

 Over/under compensated

 Harmonics (THD exceeded)

 Over temperature

 C-defect

 Warning switching operations

 Internal alert message with time stamp

 1 alarm relay

 1 relay freely programmable

 1 relay for fan control

Inputs

 Operating voltage input: 110 … 230 V AC ±15 %

 3 measuring voltage inputs: 30 … 440 V AC (L-N) / 690 V AC (L-L)

 3 current inputs: X:1A / X:5A

 1 external input

Outputs

 3 · 5 relay outputs (contact NO) as switching outputs

 3 relay outputs (contact NO) for message/alarm/fan

 2 independent isolated interfaces RS485
